Description
As part of the 2022 Building Code update, Acceptable Solution G12/AS1 Water Supplies was amended to limit the maximum allowable lead content and set out corrosion resistance properties in certain plumbing products.
In April 2024, MBIE consulted on extending the transition period end dates for both the lead and dezincification plumbing product provisions in New Zealand. Due to the positive response to the proposed changes, MBIE has announced the decision to proceed with the extension of the transition period end dates, to 1 May 2026.
