New Zealand Overhauls Earthquake-Prone Building Regulations

Major Changes to Earthquake-Prone Building System
The New Zealand Government has announced significant reforms to its earthquake-prone building (EPB) system, aiming to alleviate the financial burden on building owners while enhancing community safety. Building and Construction Minister Chris Penk stated that the current system has imposed overwhelming costs, with strengthening requirements often reaching hundreds of thousands to millions of dollars. As a result, many buildings have been left abandoned, posing increased risks during earthquakes. The new regulations will eliminate the New Building Standard (NBS) ratings, which have been criticized for being overly broad and inconsistent. Instead, the focus will shift to buildings that genuinely threaten human life in medium and high seismic zones, specifically targeting concrete structures over three storeys and unreinforced masonry buildings.
Key Features of the New System
The restructured EPB system will exempt Auckland, Northland, and the Chatham Islands from earthquake-prone classifications due to their low seismic risk. Additionally, buildings under three storeys in small towns with populations below 10,000 will no longer require full remediation, provided their façades are secured. The Government estimates that these changes will save over $8.2 billion in remediation and demolition costs, allowing communities to reinvest in local infrastructure and businesses.
Local councils will also have the authority to grant extensions of up to 15 years for remediation deadlines, providing building owners with additional time to secure funding and plan necessary work. Furthermore, the requirement for owners to upgrade fire safety and disability access simultaneously with seismic strengthening will be removed, addressing concerns that this added significantly to costs.
Perspectives on the Reforms
The Property Council of New Zealand welcomed the changes, with Chief Executive Leonie Freeman describing the previous NBS system as confusing and damaging. She emphasized that the new approach is smarter and focuses on genuine life-safety risks. ACT Party leader David Seymour also praised the overhaul, asserting that it vindicated his party's opposition to the previous regulations, which he deemed an expensive mistake.
However, the New Zealand Institute of Building Surveyors (NZIBS) expressed caution, emphasizing that while cost savings are essential, public safety must remain the top priority. NZIBS President Darryl August highlighted the need to ensure that reforms do not overlook critical building code requirements, such as fire safety and disability access.
Conflicting Reports & Gaps
While the Government anticipates that approximately 2,900 buildings will be removed from the earthquake-prone register, some experts warn that the effectiveness of these reforms in practice remains to be seen. Concerns persist regarding the potential for unintended consequences that could arise from the new regulations, particularly in relation to public safety.
