Changes to the building code restricting the use of combustible cladding

bc update

Following a number of high profile fires involving combustible, polyethylene core aluminium composite panels (ACPs) that were used as external cladding, changes have now been made to the NZ Building Code Acceptable Solutions for Protection from Fire to restrict the use of combustible cladding on buildings above three storeys. 

Under Section 271 of the Building Act 2004, MBIE has suspended the following CodeMark certificates:

  • CMA-CM40035 – Alucobond Cladding Systems
  • CMA-CM40075-I01-R01 – Apolic FR ACM Panel Cladding
  • CMA-CM40100 – Larson FR
  • CMA-CM40094 – Symonite (Alubond) Cladding Systems
  • CMA-CM40111-I02-R03 – Symonite Cladding Systems (Reynobond FR)
  • CMA-CM40193-I01-R01 – Vitrabond FR Cladding System

Manufacturers now have the opportunity to rectify issues identified with their CodeMark certificates. If these issues are not rectified, MBIE may revoke the CodeMark certificates.

This process has not unearthed evidence that these products are dangerous. 

Building Consent Authorities (BCAs) can no longer rely upon these CodeMark certificates as evidence that the products comply with the requirements of the Building Code while they are in a state of suspension. 

BCAs will be required to consider product use on a case-by-case basis when assessing a building consent, including those for which a building consent application has been received but not yet issued.

Any questions regarding the use of these CodeMark certificates can be sent to

Building owners with fire safety concerns about cladding should contact their local council, and tenants should contact their landlord. 

MBIE Audit

The Ministry of Busienss, Innovation and Employment (MBIE) commissioned an audit and peer review of CodeMark certificates attached to ACP products.

It identified that there was insufficient documentation to support the products compliance with the fire performance clauses in the New Zealand Building Code.
