Confirming the use of materials that will remain functional for the minimum periods specified (5, 15 or ≥50 years).
B2 Durability must always be considered when demonstrating compliance with each of the clauses of the Building Code. In other words, it ensures that a building will continue to satisfy the performance of the Building Code throughout its specified intended life.
Under the clause, building materials, components and construction methods are required to be sufficiently durable. They must ensure that the building, without reconstruction or major renovation, continues to satisfy the other functional requirements of the Building Code throughout its life. B2 specifies minimum durability periods building elements must meet with only normal maintenance, being not less than 50, 15 or 5 years.
Under Section 67 of the Building Act 2004, councils may consider a waiver or modification to the durability period of a building element.

The Building performance team has started work to digitise the Building Code due to growing demands from building professionals who want vital information in a format that is portable, dynamic, feature-rich and digital. We have delivered the first of our Building Code PDF documents (B1, C/AS2, D1 and E2) into our digital reader.
MBIE has historical versions of the code clause documents which can be located under 'Previous Versions' and 'Version History'. Alternatively if you cannot find the document you are looking for, you can send an email with the year and code clause you are after to firstname.lastname@example.org.
Acceptable Solutions and Verification Methods (AS and VMs) were called compliance documents. Some still have the “compliance document” title but the AS or VMs they contain are valid and unaffected by the name change.
Standards are frequently referred to in Acceptable Solutions and Verification Methods. They provide practical information and guidelines for building solutions.
Over 120 building standards used for Building Code compliance are now available for free download.
All standards, including the funded ones, can be accessed through the Standards New Zealand website.
These documents are provided for assistance. They are not intended as a means of establishing compliance with the Building Act or Building Code, and they do not have the same status accorded to Acceptable Solutions and Verification Methods under the Act.

Determinations are made by MBIE on matters of doubt or dispute to do with building work. Rulings are legally binding in relation to each case. Circumstances in one case may differ to others.
This determination considers whether two items of proposed building work comply with the relevant Acceptable Solutions. Item 1 concerns reinforcing bars to reinforce a concrete floor slab and whether the proposal complies with Acceptable Solution B1/AS1 for Building Code Clause B1 Structure. Item 2 concerns the use of a damp-proof membrane as waterproofing for a 1060mm high retaining wall and whether the proposal complies with Acceptable Solution E2/AS3 for Building Code Clause E2 External Moisture.
This determination considers whether pine vertical timber shiplap weatherboards, painted black, comply with the Building Code Clause B2 Durability, as it relates to Clause E2 External Moisture. The determination considers a number of factors that contribute to Building Code compliance.
