Updates to the Building Code will make it easier to comply
27 June 2019
Updates to the Building Code will be published on 27 June 2019 following MBIE’s public consultation and analysis of submissions.
External roof, wall claddings and external openings will prevent external moisture from causing undue dampness or damage.
This clause requires buildings to be constructed to provide adequate resistance to penetration by, and the accumulation of, moisture from the outside.
It contains requirements for roofs, wall claddings and external openings to:
The clause applies to most buildings, as set out in the limit on application in E2.2.
The Acceptable Solution to E2 External Moisture, E2/AS1, is widely used for weathertight design. About E2/AS1 provides a general overview.
Record of amendments is a record of changes to the Acceptable Solutions, Verification Methods and handbooks.
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 email@example.com.
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.
Industry groups can create their own codes of practice for the use of their products. We provide examples to help you.
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 concerns the authority's decision to refuse to issue a code compliance certificate for construction of an outbuilding that was later converted to a sleepout. The determination considers the compliance of the building work identified by the authority in its reasons for refusing to issue the code compliance certificate.
This determination considers whether the changes to a decking system to an existing building in a retirement village constitute a minor variation to the building consent issued for remedial work to the building. The determination considers whether the as-built decking system is compliant and examines the variation against the guidance issued by the Ministry on minor variations.
All products, systems and construction methods that have achieved CodeMark status will be listed here with their most up to date certificate.
