Proposed changes to the earthquake-prone building (EPB) system

The changes are designed to target buildings that pose the greatest risk to life safety, while reducing unnecessary costs and disruption, particularly in regional communities.

By enabling more cost-effective approaches to seismic strengthening, remediation will be more accessible for building owners than under the previous regime.

The proposed changes include:

• removing low risk buildings and buildings in low seismic zones (Auckland, Northland and the Chatham Islands) from the EPB system
• introducing tiered risk mitigation requirements, making use of new engineering methodologies, based on location and building type
• allowing building owners to apply for deadline extensions, to encourage incremental progress
• reducing barriers to seismic strengthening by removing the requirement for concurrent fire and accessibility upgrades.

These changes mean that:

• around 55% of EPBs (around 2,900 buildings) will be removed from the EPB system
• around 1,440 will have more affordable remediation requirements
• 840 EPBs will have no mandatory requirement for remedial work, and 
• only around 80 buildings will require a full retrofit due to the risk they pose.
