Fire performance of external wall cladding systems - Revision 2: 2020

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 (NZBC) 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.
