New Zealand Building Code updates to G12/AS1 (Amendment 14), effective from 2 May 2026, introduce strengthened requirements for plumbing products used in contact with potable water.

These updates focus on material safety, water quality, and long-term product durability.

The new requirements

The updated Acceptable Solution requires:

  • A maximum lead content of 0.25% in copper alloy plumbing products used with drinking water

  • Dezincification resistant (DZR) copper alloys for components subject to water pressure

  • Compliance verified through recognised testing and certification standards

Why this matters

These changes are intended to:

  • Reduce potential lead exposure from plumbing materials

  • Improve the durability of fittings installed behind walls and in concealed spaces

  • Ensure plumbing systems maintain performance over time

  • Provide clearer compliance standards for designers, plumbers, and building consent authorities
