Maintaining code - dates to remember

MBIE regularly updates the Building Code compliance pathways, building regulations, acceptable solutions, verification methods, guidance and information.

In recent years MBIE has consulted on proposed changes to the Building Code documents and announced the outcomes of the consultation within the same calendar year.

The last Building Code update consultation opened in May 2022. Due to the breadth of in-depth submissions received, MBIE  announced the outcomes of the consultation in November 2022 and May 2023, and will be publishing the Building Code acceptable solutions and verification methods in November 2023.

Each change usually has a transition period of 12 months, however on occasion this may vary depending on the nature and scale of the update.

The transition period for updates to the Building Code made in November 2021 ended on 2 November 2022, with an extension for some H1 clauses to May and November 2023.
