Maintaining the Building Code

To ensure the Building Code remains fit for purpose, MBIE updates selected Acceptable Solutions and Verification Methods annually.

Building Code update programme

The annual Building Code update is a maintenance programme to ensure effective management of Building Code documents. Updating the Building Code regularly helps ensure it keeps pace with modern construction methods.

Once a year, MBIE consults on the Building Code and selected Acceptable Solution and Verification Method documents and provides an opportunity for the public and sector to make submissions on the proposed changes.

Once the consultation closes and submissions are analysed, the final updates to the selected Acceptable Solutions and Verification Methods are published.

The next Building Code update consultation will open in April 2021 with changes published in November 2021 and changes taking effect the following November.

To be notified about the consultation opening and keep up to date with building sector news, sign up to our Building Controls Updates.

Outside of the consultation process, you can let us know about changes you'd like to see to Acceptable Solutions and Verification Methods by emailing us at
