Earthquake-prone buildings

Earthquake-prone buildings have a higher chance of causing damage or injury in an earthquake. The Building Act requires owners of earthquake-prone buildings to do strengthening work within a determined time frame.

EPB notice extension

The Building (Earthquake-prone Building Deadlines and Other Matters) Amendment Act 2024 extended remediation deadlines for all eligible earthquake-prone building (EPB) notices by 4 years. Updated notices and letters have now been issued to affected building owners and interested parties. Building owners are encouraged to continue with planned remediation work despite the extended timeframe.

For more detailed information about these changes, please visit the Ministry of Business, Innovation and Employment website.
