Changes to Acceptable Solution B1/AS1, preventing it from being used on liquefaction-prone ground, come into effect on 29 November 2021.
The change was initially made in November 2019, following the experience of the Canterbury earthquakes, and subsequent recommendations made by the Royal Commission of Inquiry.
It means the rules that are currently in place in Canterbury, to ensure new buildings are being built safely and strong enough to withstand liquefaction risks, will apply to the rest of New Zealand after 28 November 2021.
This change provides more clarity to local councils, Building Consent Authorities, engineers and developers and will result in safer and more resilient buildings.
More information is available on the MBIE website.
