B1/AS2 is no longer an Acceptable Solution from February 1, 2012
The Acceptable Solution B1/AS2 covers only timber barriers and is being withdrawn. This means B1/AS2 will no longer apply as an Acceptable Solution from 1 February 2012. B1/AS2 is based on loadings specified in the superseded NZS 4203:1992.

The DBH Guidance on barrier designs is now accepted as a means of compliance  can be found at the link below:

It addresses a range of areas including barrier geometry, loadings, deflection limits, and testing procedures to prove a design’s performance. It provides information for barriers constructed of timber, glass, concrete and metals, and includes a useful checklist for building consent application checking at the end of the document.

E2/AS1 Amendment 5 released 1 August 2011
Amendment 5 of Acceptable Solution E2/AS1 has been released and is in a transition period until the 31st of January, 2011. Both E2/AS1 amendments 4 and 5 can now be cited as a means of compliance until February 1, 2012.

B1/AS1 Amendment 11 released 1 August 2011
 Amendment 11 of Acceptable Solutions to B1 (AS/1 and VM/1) have been released and can now be cited as a means of compliance on your Building Consent application. Changes include new design standards referenced, including NZS 3604-2011, more stringent requirements for earthquake design and inclusion of the NASH standard for light gauge steel framing. Both Amendments 10 and 11 can be used during the transition period until the 31st of January, 2011.  This means that a designer can use either NZS 3604-1999 or NZS 3604-2011 until the end of the transition period.

PLEASE NOTE: NZS 3604 is a referenced standard in E2/AS1 and as such the two documents need to work hand in hand. This means that if you use NZS 3604-2011 for structure you must use E2/AS1 amendment 5 for weather tightness, and vice-versa.
