5 November 2020
MBIE have published updated Acceptable Solutions and Verification Methods as part of the November 2020 Building Code update programme.
Disposal of rainwater from external surfaces and confirmation surface water cannot enter the building.
This clause requires buildings and site work to be constructed to protect people and other property from the adverse effects of surface water.
It sets out performance requirements to ensure drainage systems are in place for the disposal of surface water using gravity where possible, and to avoid blockages and leakage.
Record of amendments is a record of changes to the acceptable solutions, verification methods and handbooks.
The Building Code is published in Schedule 1 of the Building Regulations 1992.
The Building Code clauses include objectives, functional requirements and performance criteria. These are mandatory provisions that all new building work must comply with.
The acceptable solutions and verification methods provided on this page are deemed to comply with Building Code clause E1.
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.
See the free standards relating to Code Clause E1.
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.
