Earthquake engineering – including working stress design

Limit state design – including serviceability limit state and ultimate limit state

Capacity design

Codified seismic design

The Building Act

The Building Code – including Building Code Requirements, classified uses and seismic resilience of structures

Building control mechanisms – including building consents, compliance schedules and exempt building work

Compliance with the Building Code – including Verification Methods, Acceptable Solutions, alternative methods and Alternative Solutions

Verification Method B1/VM1 – including AS/NZS 1170 Structural design actions and NZS 4219:2009 Seismic performance of engineering systems in buildings

Acceptable Solution B1/AS1

Level of importance

Building upgrades – including change of use and earthquake-prone buildings

National Seismic Hazard Model - the National Seismic Hazard Model provides an estimate of the likelihood and strength of an earthquake at any given site. An update of the Model was released in 2022. MBIE says the updated results will be used to inform the risk settings in building regulations.
