NZS 3604:2011 and E2/AS1 – are you current?

Most designers and builders involved in residential building work should have a copy of at least E2/AS1 and NZS 3604:2011 Timber-framed buildings, but are they the latest versions? All Acceptable Solutions, standards, and BRANZ publications undergo revision and amendment, and you do need to be working from the current or latest version.

  • For NZS 3604, it should have 2011 on the front cover and include Amendments 11 and 12, which are given in B1/AS1.
  • For E2/AS1, it should be the Third Edition including Amendment 6.
  • The BRANZ House Building Guide should be the 3rd edition.


Find out more about the BRANZ House Building Guide(external link), which includes all the new NZS 3604 and E2/AS1 changes.
