The government's changes to earthquake strengthening laws have passed their first reading.

The legislation takes a new 'risk-based' approach which removes strengthening requirements from Auckland, Northland and the Chatham Islands.

The system will move away from earthquake ratings, instead focusing on specific building features that pose a risk.

Buildings under three storeys and in towns with under 10,000 people would not need strengthening, remediation or warning notices.

Coastal Otago and part of Stewart Island will move from 'low-risk' to 'medium risk' based on updated hazard assessments.

The government expects this to save building owners $8.2 billion, by removing about 2900 buildings from the register and making remediation cheaper or unneeded for more than 2300.

The opposition said Auckland was still a seismic risk from volcanic eruptions.
