Acceptable Solutions Proposed to be Amended

Pursuant to section 29(2) of the Building Act 2004 (“Act”), I give notice of proposed amendments to the following acceptable solutions:

• G12 Water Supplies Acceptable Solution G12/AS1; and
• G12 Water Supplies Acceptable Solution G12/AS3.

The proposed changes include:

• extending the transition period end date for the new limit for lead content in copper alloy drinking water supply products in G12/AS1 to come into effect by eight-months, to 1 May 2026 (from 1 September 2025).
• extending the transition period end date for the new dezincification resistant copper alloy provision in G12/AS1 to align with the proposed extended transition period end date for the new limit for lead content in copper alloy drinking water supply products, 1 May 2026 (from 1 November 2024).
• providing a definition for lead free within G12/AS1 which supports with the new lead in plumbing product provision and aligns with equivalent definitions used in Australia and the United States of America.
• editorial changes within G12/AS1 and G12/AS3.
