Building CodeHub resources update - Recognition notices

54 new Recognition notices of the Approved Products Certified Overseas were added to BCH.

As part of the implementation of approved products certified overseas, Ministry of Business, Innovation and Employment (MBIE) published the second set of 54 recognition notices on 9 February 2026.

These notices confirm that selected plumbing and drainage products certified under the Australian WaterMark scheme meet specific clauses of the New Zealand Building Code.

The following resources have been added to Building CodeHub:
