Statement of Reasons

This notice exempts three separate classes of ship from compliance with certain specified requirements in Maritime Rules Parts 40A, 40C and 40E made under the Maritime Transport Act 1994 (see section 40AA(1)(b) of the MTA).

The exemptions in clauses 4, 5 and 6 of this notice relate to rules 40A.35(6)(a), 40C.32(6)(a), 40E.32(7)(b) respectively. Those rules set minimum requirements for piping used for carrying seawater. The piping must be of marine quality metal unless the ship is of less than 24 metres in length and constructed of non-metallic materials (such as wood or fibreglass).

In respect of the requirements under rules 40A.35(6)(a), 40C.32(6)(a), and 40E.32(7)(b), the exemptions will apply to the classes of ship described in clauses 4(2), 5(2) and 6(2) of this notice. The exemptions permit non-metallic pipes to be used to carry seawater in the specified classes of ships of metallic construction, subject to the conditions set out in clause 7.

Director may grant exemptions from maritime rules

The Director of Maritime New Zealand, being satisfied as to the matters set out in section 40AA of the Act, thinks it appropriate to grant these class exemptions because:

  • there have been improvements in technology for non-metallic piping that are not reflected in the rules. Maritime New Zealand is currently reviewing these rules. Provided that the non-metallic piping concerned meets the standards set out in the conditions, it is as effective in meeting desired objectives as the metallic piping required by the rules.

The Director is further satisfied that the exemptions meet the criteria in section 40AA(2) of the Act and conditions are appropriate as:

  • International convention requirements: the relevant rules requirements in 40A.35(6)(a), 40C.32(6)(a), and 40E.32(7)(b) do not implement any international conventions. Therefore granting the exemptions will not breach New Zealand’s obligations under any convention (section 40AA(2)(a)).
  • One of the criteria in section 40AA(2)(b) applies:
    • (ii) the manner in which the requirement has been, or is sought to be, fulfilled is as effective as or more effective than actual compliance with the requirement.
    • the alternative approaches (and conditions) provided for non-metallic piping in these exemptions meet standards published by other regulatory/ standardisation bodies, and therefore will be as effective as compliance with the existing rule-based requirements for metallic piping (section 40AA(2)(b)(ii)).
  • Risk of harm to the marine environment and safety: the alternative approach (and conditions) are considered to be as effective as compliance with the existing rule-based requirements. Accordingly, the risk of harm to the marine environment and safety will not be significantly increased by granting the exemptions (section 40AA(2)(c) and (d)).
