Buildings with aluminium composite panels (ACP)

Aluminium composite panels (ACP) are used as a cladding material on buildings. Over the last 12 months we have carried out an investigation into buildings with ACP cladding. None of the buildings assessed so far qualify as unsafe or dangerous.

​Issues with ACP cladding

Some aluminium composite panels with a polyethylene or plastic core have been linked to fire risks in tall buildings.

ACP is a common material used for many purposes, including building signage, architectural features and full building facades.

There are many types of ACP, and most are:

  • Polyethylene (PE core) panels that are combustible
  • Fire rated (FR) panels with a modified less combustible core
  • Non-combustible panels.

Buildings in Auckland with ACP cladding

Our investigation of more than 300 buildings in Auckland found 147 that appear to have ACP cladding.

There are more than 5000 residential apartments and hundreds of commercial offices in these buildings.

The findings of our investigation on ACP cladding are almost complete.

Due to the high level of public interest and the advanced state of our investigation, we think it is appropriate to release the results to date.

Safety risk of buildings with ACP cladding in Auckland

None of the buildings we have assessed during our investigation qualify as unsafe or dangerous.

We take building safety extremely seriously and will issue a formal warning for buildings that pose a significant risk.

If you are buying a property in a building with ACP cladding

Our intention is to put information about the cladding on individual property files of residential apartments. We are currently working out how this will be documented.

Before purchasing a property, we strongly encourage potential buyers to get copies of the property file and the Land Information Memorandum report (LIM).

If you own a property in a building with ACP cladding

Building owners have the option to replace all or any of the cladding.

For many buildings with ACP, coverage is limited and the likelihood of it being involved in a fire will be very small. For buildings with a large amount of ACP, full removal of the cladding may be an option.

However, there are typically many safety features present within the buildings and whilst full or partial removal of any cladding will reduce any potential risk, there are many options available that could mitigate the risk.

We advise seeking advice from your insurers and ensuring all fire safety features are in good working order.

If you are a tenant living in a building with ACP cladding

None of the buildings assessed are unsafe, but you should insist that your landlord provides the following fire safety measures:

  • Fire safety systems are maintained and are in good working order.
  • Working smoke alarms or detectors (compulsory in all rental homes).
  • Informs you about their building's evacuation procedures and escape routes.
