AUDIT REPORT
TO THE READERS OF THE FINANCIAL STATEMENTS OF POWERCO LIMITED - ELECTRICITY DIVISION
We have audited the financial statements of Powerco Limited - Electricity Division. The financial statements provide information about the past financial performance of Powerco Limited - Electricity Division and its financial position as at 30 June 2006. This information is stated in accordance with the accounting policies.
Directors' Responsibilities
The Commerce Commission's Electricity Information Disclosure Requirements 2004 made under section 57T of the Commerce Act 1986 require the Directors to prepare financial statements which give a true and fair view of the financial position of Powerco Limited - Electricity Division as at 30 June 2006, and results of operations and cash flows for the year then ended.
Auditor's Responsibilities
It is our responsibility to express an independent opinion on the financial statements presented by the Directors and report our opinion to you.
Basis of Opinion
An audit includes examining, on a test basis, evidence relevant to the amounts and disclosures in the financial statements. It also includes assessing-
· the significant estimates and judgments made by the Directors in the preparation of the financial statements; and
· whether the accounting policies are appropriate to Powerco Limited - Electricity Division's circumstances, consistently applied and adequately disclosed.
We conducted our audit in accordance with generally accepted auditing standards in New Zealand. We planned and performed our audit so as to obtain all the information and explanations which we considered necessary. We obtained sufficient evidence to give reasonable assurance that the financial statements are free from material misstatements, whether caused by fraud or error. In forming our opinion we also evaluated the overall
adequacy of the presentation of information in the financial statements.
Other than in our capacity as auditor and provision of taxation and accounting advice, we have no relationship with or interests in Powerco Limited.
Qualified Opinion
Disclosure of Transition to New Zealand Equivalents to IFRS
New Zealand Equivalent to International Financial Reporting Standards 1 (NZ IFRS 1) "First-time Adoption of New Zealand Equivalents to International Financial Reporting Standards 1 requires reconciliation of the entity's equity reported under previous New Zealand Generally Accepted Accounting Practice (NZ GAAP) to its equity under New Zealand equivalents to International Financial Reporting Standards (NZ IFRS) at the date of transition to NZ IFRS. This information has not been disclosed in the financial statements.
Compliance with Section 2.8(a) of the Commission Electricity Information Disclosure Handbook
Under section 2.8(a) of the Commerce Commission Electricity Information Disclosure Handbook an entity must not restate comparative information, even where this would result in a departure from Generally Accepted Accounting Practice (GAAP). The comparative period has been restated due to the transition to NZ IFRS which was undertaken during the year.
In these respects alone we have not obtained all the information and explanations that we have required.
In our opinion, except for adjustments that would have been necessary to comply with NZ IFRS 1 and section 2.8(a) of the Commerce Commission Electricity Information Disclosure Handbook:
· proper accounting records have been maintained by Powerco Limited - Electricity Division as far as appears from our examination of those records; and
· the financial statements referred to above-
a) comply with generally accepted accounting practice in New Zealand; and
b) give a true and fair view of the financial position of Powerco Limited - Electricity Division as at 30 June 2006 and the results of its operations and cash flows for the year then ended; and
c) comply with the Electricity Information Disclosure Requirements
Our audit was completed on 6th December 2006 and our qualified opinion is expressed as at that date.

POWERCO LIMITED
POWERCO LIMITED
Electricity Division
Statement of Accounting Policies for the Financial Statements for the Year ended 30 June 2006
Reporting Entity
Powerco Limited is a company registered under the Companies Act 1993. The group consists of Powerco Limited and its subsidiaries.
The following activities were the principal activities undertaken by Powerco Limited throughout the period:
* Distribution of electricity and value added services.
* Distribution of gas and value added services.
These financial statements have been prepared to comply with the provisions of Section 44 of the Energy Companies Act 1992, the Companies Act 1993, and the Financial Reporting Act 1993.
Special purpose financial statements
These financial statements are made pursuant to Powerco's obligations under the Electricity Information Disclosure Regulations 2004.
The Lines Business is treated as the core business and corporate activities are accounted for through the Line and Other Business financial statements. Powerco has adopted the avoidable cost allocation methodology stipulated in the Electricity Information Disclosure Regulations.
There are various matters, which relate across the whole integrated business. These are shown specifically in the respective notes where relevant.
Adoption of new and revised International Financial Reporting Standards
In the current year, the Company had adopted all of the applicable new and revised Standards and Interpretations issued by the International Accounting Standards Board (the IASB) and the International Financial Reporting Interpretations Committee (IFRIC) of the IASB that are relevant to its operations and effective for accounting periods beginning on or after 1 January 2005. The adoption of these new and revised Standards and Interpretations has resulted in changes to the Company's accounting policies in the following areas that have affected the amounts reported for the current or prior years:
· Accounting for Income Tax
· Financial Instruments
The transition to NZ IFRS is accounted for in accordance with NZ IFRS-1.
Significant accounting policies
The financial statements have been prepared on the historical cost basis, except for certain borrowings and financial instruments. Financial derivatives are carried at fair value and borrowings which have effective fair value hedges are carried at amortised cost adjusted for the fair value of interest rate risk covered by the effective hedge. The principal accounting policies adopted are set out below.
a) Critical accounting estimates and judgements
In the process of applying the groups accounting policies management have made no judgements that have had a significant effect on the amounts recognised in the financial statements.
The key assumptions concerning the future and other key sources of estimation uncertainty at 30 June 2006, that have had a significant risk of causing a material adjustment to the carrying amount of assets and liabilities are discussed below.
b) Cash and cash equivalents
Cash and cash equivalents comprise cash in hand, cash in banks and investments in money market instruments, net of outstanding bank overdrafts. Bank overdrafts are shown within borrowings in the balance sheet.
c) Property, Plant and Equipment
All items of property, plant and equipment are initially recognised at cost in the statement of financial position. Cost includes the value of consideration exchanged, or fair value in the case of donated or subsidised assets, and those costs directly attributable to bringing the item to working condition for its intended use.
Land and buildings are revalued from time to time for insurance purposes only. Optimised Deprival Value (ODV) is obtained from an independent registered valuer. Any impairment is recognised for accounting purposes and recognised in the Statement of Financial Performance.
d) Depreciation of Property, Plant and Equipment
Depreciation is calculated on a straight-line basis for Network Systems and on diminishing value for all other assets, to write off the cost of the assets (other than land) over the life of the assets.
Depreciation rates based on remaining useful life, for major classes of asset are:
Land Not Depreciated
Buildings 50 years
Plant and Equipment 5 to 10 years
Network Systems 10 to 65 years
e) Borrowing Costs
Borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets, until such time as the assets are substantially ready for their intended use or sale.
All other borrowing costs are recognised in profit or loss in the period in which they are incurred.
f) Financial assets
Financial assets are recognised and derecognised on trade date where purchase or sale of an investment is under a contract whose terms require delivery of the investment within the timeframe established by the market concerned, are initially measured at fair value, net of transaction costs.
Subsequent to initial recognition, investments in subsidiaries are measured at cost in accordance with NZ IAS-27. Other financial assets are classified into one of four categories; financial assets at fair value through the profit or loss, held to maturity investments, available for sale financial assets or loan and receivables. At balance date the Company had the following classes of financial assets:
Loans and receivables
Trade receivables and other receivables are recorded at amortised cost less impairment.
g) Financial liabilities
Financial liabilities are recognised when the entity became party to the contractual provisions of the instrument.
h) Term Debt
All loans and borrowings are initially recognised at cost, being the fair value of the consideration received net of issue costs associated with the borrowing. Subsequent to initial recognition, loans and borrowings are carried at amortised cost. Borrowing costs are recognised as an expense when incurred, except to the extent that they are capitalised in accordance with e) above.
All interest bearing loans and borrowings are measured at amortised cost using the effective interest rate method which allocates the cost through the expected life of the borrowing. Amortised cost is calculated taking account of issue costs, and any discounts or premiums on draw down.
After initial recognition for those interest-bearing loans and borrowings where fair value hedge accounting is applied, the loan balance is adjusted for the change in the hedge risk only. The Company policy is to hedge the interest/foreign currency risk associated with term debt with financial instruments on matched terms.
Borrowings are classified as current liabilities (either advances and deposits or current portion of term debt) unless the group has an unconditional right to defer settlement of the liability for at least 12 months after the balance sheet date.
i) Trade and other payables
Trade payables and other accounts payable are recognised when the consolidated entity becomes obliged to make future payments resulting from the purchase of goods and services. Subsequent to initial recognition, trade payables and other accounts payable are recorded at amortised cost. Given the nature of these liabilities amortised cost equals their notional principal.
j) Derivative Financial Instruments
Financial derivatives are initially recognised in the balance sheet at fair value on the date a derivative contract is entered into and are subsequently measured at their fair value on each balance sheet date, though the method of recognising the resulting gains and losses is dependent on whether hedge accounting is applied. When derivative contracts are entered into, the group designates them as either;
· Hedges of the fair value of recognised assets or liabilities (fair value hedge); or
· Hedges of forecast transactions or firm commitments (cash flow hedge) which hedge exposures to variability in cash flows; or
· Hedges of net investments in foreign entities; or
· Other derivative financial instruments not meeting hedge accounting criteria.
The fair values of financial derivatives are determined by reference to the market quoted rates input into valuation models for interest and currency swaps, forwards and options. Changes in fair value of derivatives are recognised:
· For fair value hedges which are highly effective, the movements are recorded in the income statement alongside any changes in the fair value of the hedged items;
· For cash flow hedges that are determined to be highly effective to the extent the hedges are effective, the movements are recognised in equity with the ineffective portion recognised in the income statement; and for those that are ineffective the movements are recognised in the income statement;
· For hedges of net investments in foreign entities that are highly effective, the effective portion of the movements is recorded in equity (currency translation reserve) and the ineffective portion is recognised in the income statement.
· All other movements in the fair value of derivative financial instruments are recorded in the income statement.
Hedge accounting is discontinued prospectively when the hedging instrument expires or is sold, terminated or exercised, or no longer qualifies for hedge accounting. At that point in time, if the forecast transaction is still expected to occur, any cumulative gain or loss on the hedging instrument is recognised in equity until the forecasted transaction occurs. If a hedged transaction is no longer expected to occur, the net cumulative gain or loss recognised in equity is transferred to the income statement for the period.
k) Employee Entitlements
Provision is made for benefits accruing to employees in respect of wages and salaries, annual leave, long service leave and sick leave when it is probable that settlement will be required and they are capable of being measured reliably.
Provisions made in respect of employee benefits expected to be settled within 12 months, are measured at their nominal values using the remuneration rate expected to apply at the time of settlement.
Provisions made in respect of employee benefits which are not expected to be settled within 12 months are measured as the present value of the estimated future cash outflows to be made by the consolidated entity in respect of services provided by employees up to reporting date.
l) Defined Superannuation Plans
For Defined Contribution Superannuation Plans, the Group recognises and expenses the obligation during the period they arise.
There are a small number of employees that are part of a state Defined Benefit Superannuation plan. The Group has no legal or constructive obligation to pay future benefits, the Crown guarantees these benefits, as a result the plans are accounted for as a defined contribution plan.
m) Impairment
Intangible assets that have indefinite useful lives are not subject to amortisation and are assessed for impairment at each reporting date. If the estimated recoverable amount of an asset is less than its carrying amount, the asset is written down to its estimated recoverable amount and an impairment loss is recognised in the statement of financial performance.
A cash generating unit is the lowest group of assets for which there are separately identified cash flows.
At each reporting date, the consolidated entity reviews the carrying amounts of its tangible and intangible assets to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any). Where the asset does not generate cash flows that are independent from other assets, the consolidated entity estimates the recoverable amount of the cash-generating unit to which the asset belongs.
Goodwill, intangible assets with indefinite useful lives and intangible assets not yet available for use are tested for impairment annually and whenever there is an indication that the asset may be impaired. An impairment of goodwill is not subsequently reversed.
Recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than its carrying amount, the carrying amount of the asset (cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognised in profit or loss immediately, unless the relevant asset is carried at fair value, in which case the impairment loss is treated as a revaluation decrease.
Where an impairment loss subsequently reverses, the carrying amount of the asset (cash-generating unit) is increased to the revised estimate of its recoverable amount, but only to the extent that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognised for the asset (cash-generating unit) in prior years. A reversal of an impairment loss is recognised in profit or loss immediately, unless the relevant asset is carried at fair value, in which case the reversal of the impairment loss is treated as a revaluation increase.
n) Share Capital
Ordinary shares are classified as equity.
Costs directly attributable to the issue of new shares are shown in equity as a deduction from the proceeds.
p) Dividend distribution
Dividend distribution to the company's shareholders is recognised as a liability in the group's financial statements in the period in which the dividends are declared.
p) Leases
Operating lease payments, where the lessors effectively retain substantially all the risks and rewards of ownership of the leased items, are included in the determination of profit before taxation in equal instalments over the lease term, except where another systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed.
q) Revenue Recognition
Revenue is recognised at the fair value of sales of goods and services, net of GST, rebates, discounts and capital contributions.
Revenue is recognised as follows:
(a) Rendering of Services
Revenue from services is recognised in the accounting period in which the services are rendered based upon useage or volume throughput during that period.
r) Taxation
The amount recognised for current tax is based on the net profit for the period as adjusted for non-assessable and non-deductible items. It is calculated using tax rates that have been enacted or substantively enacted by the reporting date.
Deferred income tax is provided, using the comprehensive balance sheet liability method, on all temporary differences at the balance sheet date between the tax base of the assets and liabilities and their carrying amounts in the consolidated financial statements.
The following temporary differences are not provided for: goodwill, the initial recognition of assets or liabilities that affect neither accounting nor taxable profit, and the temporary differences relating to investments in subsidiaries, where the consolidated entity is able to control the reversal of the temporary differences and it is probable that the temporary differences will not reverse in the foreseeable future.
The carrying amount of deferred income tax assets is reviewed at each balance sheet date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred income tax to be utilised.
Deferred income tax assets and liabilities are measured at tax rates that are expected to apply to the year when the asset is realised or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at balance sheet date.
The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow the manner in which the consolidated entity expects, at the reporting date, to recover or settle the carrying amount of its assets and liabilities.
Deferred tax assets and liabilities are offset when they relate to income taxes levied by the same taxation authority and the company/consolidated entity intends to settle its current tax assets and liabilities on a net basis.
Current and deferred tax is recognised as an expense or income in the income statement, except when it relates to items credited or debited directly to equity, in which case the deferred tax or current tax is also recognised directly in equity, or where it arises from the initial accounting for a business combination, in which case it is taken into account in the determination of goodwill or excess.
Income tax relating to items recognised directly in equity is recognised in equity and not in the income statement.
s) Statement of Cash Flows
The statement of cash flows is prepared exclusive of GST, which is consistent with the method used in the statement of financial performance. For the purposes of the Statement of Cash Flows, cash and cash equivalents includes cash on hand, cash in banks and investments in money market instruments, net of outstanding bank overdrafts.
Operating activities include all transactions and other events that are not investing or financing activities.
Investing activities are those activities relating to the acquisition and disposal of current and non-current investments and any other non-current assets.
Financing activities are those activities relating to changes in the equity and debt capital structure of the company and group and those activities relating to the cost of servicing the company's equity capital.
t) Comparative information - financial instruments
The Company has elected not to restate comparative information for financial instruments within the scope of NZ IAS -32 'Financial Instruments: Disclosure and Presentation' and NZ IAS -39 'Financial Instruments: Recognition and Measurement', as permitted on the first time adoption of NZ IFRS.
The accounting policies applied to accounting for financial instruments in the current financial yare are detailed in notes 1 a) to s). The following accounting policies were applied to accounting for financial instruments in the comparative financial year.
Receivables
Accounts receivable are valued at expected realisable value, after providing for doubtful debts. All known bad debts have been written off during the period under review.
Financial Instruments
The company has various financial instruments with off-balance sheet risk for the primary purpose of reducing its exposure to fluctuations in interest rates. Financial instruments as at 30 June 2005 consisted of interest rate swaps and cross currency swaps. While these financial instruments are subject to risk that market rates may change subsequent to acquisition, such changes would generally be offset by opposite effects on the items being hedged.
For interest rate swap agreements entered into in connection with the management of interest rate exposure, the differential to be paid or received is accrued as interest rates change and is recognised as a component of interest income/expense over the life of the agreement.

The $4.938 million adjustment shown above in equity represents the recognition of interest rate swaps and cross currency swaps at 30 June 2005 ($33.161m), deferred tax on interest rate swaps ($2.432m) and the adjustment to the carrying value of loans covered by fair value hedges (adjustment for the fair value of interest rate risk on loans hedges by fair value hedges $25.791 m). This adjustment has been made to the hedging reserve as the hedges were effective hedges under the superseded accounting policies.
The $33.161m adjustment above represents the fair value of hedges at 30 June 2005. This adjustment was done to record the derivatives as a separate class of liability. The $25.791m adjustment represents the fair value adjustment to hedged loans. The $2.432m relates to deferred tax on the hedges.
The following transitional provisions have an effect on future profits:
· The effectiveness of hedging relationships are assessed from 1 July 2005, no adjustment is made in relation to hedges under the superseded policies which were not highly effective before 1 July 2005.
The main adjustments necessary that would make the comparative financial statements comply with NZ IAS -32 and NZ IAS -39 are listed below. Similar adjustments were made at 1 July 2005 to restate the opening financial position of the company and consolidated entity to a position consistent with the accounting policies specified in note 1a) to s):
· The recognition and measurement of all derivatives (including any embedded derivatives) at fair value;
· The recognition in profit or loss of the movement in the fair value of derivatives which did not qualify for hedge accounting or were not designated as hedging instruments;
· The transfer of deferred hedging gains and losses recognised as assets and liabilities arising from a cash flow hedge of a forecast transaction to the hedging reserve;
· The deferral in equity of the effective portion of the movement in fair value of derivatives accounted for as a cash flow hedge;
· The recognition in profit or loss of the movement in fair value of derivatives accounted for as a fair value hedge and the fair valuing of hedge items;
· The adjustment to the carrying amount of items that would qualify as a fair value hedge under NZ IFRS and were designated as a hedge under previous GAAP for the lower of the cumulative change in fair value of the hedge item for the designated risk and the cumulative change in fair value of the hedging instrument;
· The recognition of any current or deferred taxes in relation to the adjustments described above.
It is not practicable for the company to detail the amounts of the adjustments to profit and loss and to opening retained earnings for the comparative period had the new accounting policies been applied from the beginning of the comparative period. In addition, it is not practicable for the company to detail for the current period, the amounts of the adjustments resulting to each financial statement line item as a consequence of applying the accounting policies specified elsewhere in note 1.

The fair value of financial assets and financial liabilities are determined as follows:
- For floating rate debt carrying value approximates fair value due to continuing interest rate reset.
- For fixed rate debt opposing floating rate derivative instruments matching tenor and term are used in offset position to calculate fair values. The movements in these derivatives approximate movements in market values.
- For derivative instruments fair value is based on quoted prices.

ELECTRICITY DIVISION
2 DERIVATIVE FINANCIAL INSTRUMENTS
a) Powerco Limited enters into NZD floating to fixed interest rate swap agreements to reduce the impact of changes in floating interest rates on its borrowings and thus reduce variability in cash flows. Fixed to floating instruments are entered into in order to hedge the changes in fair value of fixed rate NZD debt. Powerco Limited also utilises Cross Currency interest swaps to hedge against the variations in interest costs and fair value of the USD Private placement debt.
Derivative instruments are initially recognised at fair value on the contract date and subsequently measured at their fair value on each balance sheet. The method of recognising the resulting gain or loss depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged. The Group designates certain derivatives as either (i) hedges of highly probable forecast transactions (cash flow hedges), or (ii) hedges of the fair value of recognised assets or liabilitites or a firm commitment (fair value hedges).
The Group documents, at the inception of the hedge transaction, the relationship between hedging instruments and hedged items, as well as its risk management objective and hedging strategy. The Group also documents its assessment, both at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items.
(i) Cash flow hedges
The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges are recognised in equity. The gain or loss relating to the ineffective portion is recognised immediately in the Income Statement. Amounts accumulated in equity are transferred to the Income Statement in the same period in which the hedged item affects the Income Statement.
When a hedging instrument expires or is sold, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss existing in equity at that time remains in equity and is recognised when the forecast transaction is ultimately recognised in the Income Statement. When a forecast transaction is no longer expected to occur, the cumulative gain or loss reported in equity is immediately transferred to the Income Statement.
(ii) Fair value hedges
Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in the Income Statement, together with any changes in the fair value of the hedged risk.
(iii) Derivatives that do not qualify for hedge accounting
Certain derivative instruments are undertaken as hedges of economic exposures but do not qualify for hedge accounting. Changes in the fair value of any derivative instruments that do not qualify for hedge accounting are recognised immediately in the Income Statement.
The fair value of financial instruments are determined by reference to the market quoted rates.
All derivative instruments are carried on balance sheet at their fair values. Movements on the hedging reserve are shown in the Statement of Shareholders' Equity.
The Group holds the following financial instruments:
1 Interest rate swaps
The Group receives New Zealand fixed interest rates and pays New Zealand dollar floating interest rates. The hedge is a fair value hedge and was entered into on terms matched to the underlying obligation.
The nominal value of the hedge is $252,000,000 (2005: $252,000,000)
The fair value of the hedge is -$6,426.693 (2005: -$4,528,454)
2 US Cross Currency Interest rate swaps
The Group receives US dollar fixed interest and pays NZ dollar floating interest. The hedge is both a fair value hedge and hedges the movements in currency that would affect interest payments and final repayment at maturity, these were entered into at terms to match the underlying obligation.
The nominal value of the hedge is $211,871,532 (2005: $211,871,532)
The fair value of the hedge is -$21,075,924 (2005: -$28,966,452)
3 Interest rate swaps
The Group receives NZ dollar floating interest rates and pays NZ dollar fixed interest. The hedge is to fix the variable floating obligations efficiently as per the hedge policy and the treasury policy and is on matched terms. The hedge is a cash flow hedge.
The nominal value of the hedge is $162,000,000 (2005: $180,000,000)
The fair value of the hedge is -$2,004,023 (2005: -$4,503,380)
4 Interest rate swap
To swap back fixed New Zealand dollar debt converted to floating back to fixed debt. The swap is used to match the interest rate profile in accordance with the Board strategy and is on matched terms. Hedge accounting is not applied to these swaps.
The nominal value of the hedge is $357,840,000 (2005: $451,440,000)
The fair value of the hedge is $926,822 (2005: -$3,624,895)
5 Interest rate swap
To convert floating New Zealand debt from US dollar fixed debt to fixed New Zealand dollar debt. The swap is used to modify the debt profile in accordance with the Board strategy and is on matched terms. Hedge accounting is not applied to these swaps.
The nominal value of the hedge is $399,600,000 (2005: $66,960,000)
The fair value of the hedge is -$188,886 (2005: $233,618)
6 Interest rate swaps
To unwind floating to fixed swaps which existed when the hedging policy was changed. These are to cancel previous interest rate swaps and match the terms of those including termination date and rolls. Hedge accounting is not applied to these swaps.
The nominal value of the swap is $57,600,000 (2005: $169,200,000)
The fair value of the swap is -$633,376 (2005: $1,431,150)

7 Interest rate swaps
Historical swaps floating to fixed swaps which are cancelled by number six above on match term and rolls basis. Hedge accounting is not applied to these swaps.
The nominal value of the swap is $57,600,000 (2005: $169,200,000)
The fair value of the swap is $168,371 (2005: -$3,108,446)
Total notional principal of instruments recognised $1,498,511,532 (2005: 1,500,671,532)
Total fair value of instruments recognised -$29,233,710 (2005: -$43,066,859)
All cash flow hedges above are on matched terms. The maturities are the same as the financial liabilities recorded in note 12. The Group's policy is to refloat any fixed rate debt, thus giving a totally floating portfolio, then re hedge as per parameters in the treasury policy. This has the effect that some fixed rate hedges are applied against floating rate hedges. In line with NZ IAS39 these are not hedge accountable and thus movements in the mark to market value of these is passed through to the Income Statement.
The Group's New Zealand Dollar (NZD) and foreign currency fixed rate debt is converted to floating NZD debt through the use of derivatives, with these exactly matching the term and nominal value of the debt. At the point of issue the nominal value of the bonds was equivalent to the fair value, and the fair value of the derivative was zero. The marking to market of the derivatives outlines movements in interest rates or currency rates.
Powerco bonds are able to be traded on the NZDX and an active secondary market exists. This valuation method assumes a constant credit rating.

(f) Financial Instruments
Risk Management
The Group engages in business in Australia and New Zealand and has currency expenses relating to the Australian dollar and US dollar. In the normal course of events the Group is exposed to loss through
(a) Market risk
(b) Credit risk
(c) Liquidity risk.
The Group's risk programme recognises the unpredictibility of financial markets and seeks to minimise the potential adverse effects of market movements. The Group uses derivative financial instruments for this purpose, but does not engage in holding instruments for trading or speculation.
Management of this risk is performed in accordance with the policies approved by the Board of Directors. These cover both detailed policies and specific areas such as foreign exchange risk, interest rate risk, credit risk and liquidity risk as well as the use of derivatives and appropriateness of counter parties.
(a) Market Risk
(i) Foreign Exchange Exposures
The Group operates in New Zealand and Australia and has foreign exchange exposures arising from US dollar denominated debt and investments in Australian operations. This exposes the Group to potential gains and losses arising from currency movements.
The Group policy relating to US dollar denominated debt is to minimise the exchange rate exposure by use of matching hedges taken out at the time the loans were drawn down. With regards to the independent foreign subsidiary, Powerco Austalian Group Pty Limited, there is no net investment hedging.
(ii) Interest Rate Exposures
Interest rate risk is the risk that interest rates will change, increasing or decreasing the cost of borrowing or lending. The Company's short-term borrowings are on a floating daily interest rate. Non-current debt is funded by the fixed coupon bonds and Powerco's commercial paper program based on 90 day Bank Bills.
Powerco has entered into interest rate swap agreements to reduce the impact of the changes in interest rates on its borrowings. As at 30 June 2006, Powerco Limited had interest rate swap agreements with registered banks. The weighted average of the interest rate swap agreements (excluding the reverse swap agreements) produce an interest rate of 6.68% p.a.
(b) Credit Risk
Financial instruments which potentially subject the Company to credit risk principally consist of bank balances and accounts receivable. There are no significant concentrations of credit risk. These accounts are subject to a Board Prudential Supervision Policy which is used to manage the exposure to credit risk. As part of this policy, limits on exposures have been set and are monitored on a regular basis. Cash deposits are only made with registered banks. The maximum credit risk is the carrying value.
(c) Liquidity Risk
Liquidity risk is the risk that the Group may be unable to meet its financial obligations as they fall due. This risk is managed by maintaining sufficient cash and deposits together with access to committed credit facilties.
3 WORKING CAPITAL ADVANCES FACILITY
Powerco Limited operates a wholesale capital advance facility with the Commonwealth Bank of Australia for up to $30 million. The facility, dated 22 March 2005, replaced a similar facility held with Bank of New Zealand for up to $15 million. As at 30 June 2006, funds to the amount of $28.5 million were drawn down on the facility, offset by unrealised deposits of $475,643 (2005: funds drawn of $26.2 million, offset by unrealised deposits of $410,894). The facility is based on a revolving credit arrangement and as such does not have set repayment dates. The facility expires on 22 March 2008 but is subject to automatic renewal for a further period. The facility has the benefit of the Security Trust Deed, as a Senior Secured Debt Facility. This facility had interest rates ranging from 6.90% to 7.40%.
At year end the amount of the bank overdraft allocated to the electricity division was $15.89 million.
There is no right of set-off between any of the facilities.

7 CONTINGENT LIABILITIES AND COMMITMENTS
As Powerco is an integrated business, this disclosure relates to the business as a whole.
Legal claim
Powerco Limited has been named as a second defendant in a claim issued by Todd Energy Limited against Transpower Limited. The plaintiffs allege various breaches of the Commerce Act 1986 and claim various declarations and injunctions together with damages. The damages amount is presently unquantified. The claim is being defended by Powerco, which contends that it is not in breach of any of its obligations. No provision for the claim has been included in the financial statements.
Powerco Energy Services Pty Limited is the respondent in an arbitration commenced by KT Pty Limited, a sub-contractor who was performing work on the Gas Distribution Network in Tasmania. The plaintiffs allege variations to the contract, delay costs and claim damages. The claim is currently being defended by Powerco Energy Services Pty Limited, which contends that it is not in breach of the contract and has brought a counter claim against the plaintiffs for the cost of defective work. The damages amount is presently unquantified and no provision for the claim has been included in the financial statements.
Contracts
Powerco Limited has a contract with Tenix Alliance New Zealand Limited (Tenix) , who provide electricity and gas field services. There is a condition in the contract that states that a payment is made to Tenix for performing better than budgeted and a payment is made to Powerco if performance does not meet budget. The amount of the payment is determined by a predetermined calculation in the contract. At this time, any payment to or from Powerco cannot be quantified.
Contribution from Tasmanian government
In January 2004, prior to the acquisition, Powerco received a contribution from the State Government of Tasmania amounting to AUD $8 million, for the building of a gas distribution network in Tasmania. This payment, known as an establishment contribution, is consideration for taking all necessary steps to incorporate a gas distribution entity and procuring that the gas distribution entity is established with access to the necessary expertise, assets and financial capability to undertake the Stage 1 Development Agreement with the Crown in Right of the State Government of Tasmania dated 30 April 2003. There is a refund mechanism on sale of assets or the shares in the gas distribution entity whereby Powerco must repay the State an amount equal to the lesser of the establishment contribution and the asset/equity profit.
In May 2005, Powerco Limited received a contribution from the State Government of Tasmania amounting to NZD $20.6 million (AUD $18.4 million), as an advance on the commencement of stage II of the gas distribution network built in Tasmania. An amount of NZD $72,000 (AUD $64,000) has been recognised as revenue in this financial period, based on calculating a set percentage of the depreciation charge of the capitalised project costs. There is a refund mechanism whereby Powerco Limited must repay the State if Powerco fails to perform certain obligations under the agreeement. If this occurs Powerco is required to refund a pro rata amount based on uncompleted construction at the time of termination. Refer to notes 11 and 15 for income in advance.

10 RECONCILIATION OF NZ IFRS WITH AMOUNTS PREVIOUSLY RECORDED UNDER NZ GAAP
Powerco Limited changed its accounting policies on 1 April 2004 to comply with New Zealand equivalents to International Financial Reporting Standards (NZ IFRS). The transition to NZ IFRS is accounted for in accordance with NZ IFRS 1 First time Adoption of New Zealand equivalents to International Financial Reporting Standards (NZ IFRS 1).
An explanation of how the transition from superseded policiies to NZ IFRS has affected the company and consolidated entity's financial position, financial performance and cash flows is set out in the following tables and the notes that accompany the tables.
(a) Reconciliation of Net Profit/(Loss) after Tax 12 months

measure network assets on transition to NZ IFRS at fair value and has used that fair value as the item's deemed cost at that date. The effect of the revalution is to increase the carrying value by $136.9 million (parent $128.4 million).
(c) Under superseded policies deferred funding costs were recognised as non current assets. Under NZ IFRS deferred funding costs are included in borrowing to which they relate.
(d) The deferred tax asset under superseded policies has been reclassified to liabilities as a result of the change in the balance due to reclassification of deferred tax using the balance sheet approach.
(e) Under superseded policies cash balances were netted with the bank overdraft. Netting is not allowed under NZ IFRS unless it meets specific criteria. This criteria has not been met and as a result the cash and bank overdraft have been reported gross.
(f) Under the superceded policies the government grant funding was recognised on a milestone basis, whereas under NZ IFRS it is being recognised over the life of the asset to which the funding relates to.
Effect of NZ IFRS on the Cash Flow Statement
There are no material differences between the cash flow statement presented under NZ IFRS and the cash flow statement presented under the superseded policies.
