Transition period has ended for 2023 Building Code updates

Posted: 5 November 2024

In November 2023 MBIE published updated acceptable solutions and verification methods which support plumbing and drainage work, and protection from fire. A transition period of one year was provided when both the previous and new versions of the documents could be used.

The transition period for these updates ended on 1 November 2024 and the previous versions of these documents can now no longer be used.

The protection from fire updates included amendments to Acceptable Solutions C/AS1, C/AS2, F7/AS1 and Verification Method C/VM2.

The plumbing and drainage updates included amendments to the acceptable solutions and verification methods for G12 Water Supplies, G13 Foul Water and E1 Surface Water.

MBIE publishes regular updates to Building Code documents to support Aotearoa New Zealand to deliver safe, healthy and durable buildings. These updates to the building code are published with transition periods which allow the continued use of the existing documents while the sector becomes familiar with the new versions. This provides time to ensure that the changes are implemented smoothly.

You can check the date that a document became effective in the document status section of the relevant acceptable solution or verification method. This section sets out the dates that the most recent version became effective on, and the date that a previous version can be used until. The previous version can be used up to and including the transition end date. After the transition period has ended only the current version can be used as a deemed to comply solution.

The transition period for the 2023 Building Code updates ended on 1 November 2024. This means that building consent applications submitted on or after 2 November 2024 that use one of the updated acceptable solutions or verification methods as a means of compliance should now use the most recent versions of the documents.
