There are six Building Code clauses related to protecting people in and around buildings, limiting fire spread and helping firefighting and rescue.

Supporting them are two verification methods and three acceptable solutions, based on the occupant activity in all or part of a building.

Each clause has an objective (see C1), and there may be specific products and determinations under each clause. However, most guidance applies to all of the clauses and most requirements cross over a number of other Building Code clauses, including structure and access.

Change of use and alterations of a building can trigger the need for upgrades to the fire safety systems.

Significant high-rise fire events globally have increased our understanding of how fire spreads externally and within modern facade construction. In 2019 MBIE reviewed the existing methods used to demonstrate compliance of external wall cladding systems with building regulations' fire safety objectives. Guidance was provided on how New Zealand Building Code requirements should be interpreted and whether international alternative fire tests and evaluation methods are suitable for use here.

Based on the feedback received on the 2019 guidance and subsequent engagement with the industry stakeholders, MBIE has released this revision of guidance on fire performance of external wall cladding systems.

Clarifies what test methods can/may be used to determine fire performance of external cladding systems to demonstrate compliance with Building Code.
