NZ Listed Property Firms Cautiously Embrace Earthquake-Prone Building Reforms

Oct 09, 2025

Highlights:

  • New Zealand’s listed property firms have expressed support for the government’s proposed overhaul of the earthquake-prone building (EPB) system, a reform expected to deliver as much as NZ$8.2 billion in savings on remediation and demolition expenses.
  • The reforms propose removing the New Building Standards (NBS) rating, excluding Auckland from the EPB regime, and giving councils greater discretion in enforcement.
  • While the sector sees relief ahead, analysts warn that cost savings will differ across buildings depending on location, structure, and council interpretation of the new rules.

Optimism with Caveats in the Property Sector

A range of New Zealand’s listed property companies have responded positively to the Government’s proposed reform of earthquake-prone building (EPB) laws. The changes, introduced via a new bill announced in late September, aim to refocus the EPB regime and could deliver up to NZ$8.2 billion in savings for remediation and demolition. At the time of writing, property firms see opportunity—though with varied expectations on actual costs.

Key Reform Features & Sector Reactions

The proposed system would remove the New Building Standards (NBS) rating scale, exclude Auckland from the EPB regime, and give councils increased discretion in applying the rules. Many existing buildings would be reclassified or fall outside the regime entirely. These shifts are generally welcomed by property owners and developers, who say the previous framework imposed heavy financial burdens—especially for older structures in lower-risk areas. That said, analysts caution that the cost relief will not be uniform. Savings depend heavily on individual building conditions, location, structural design, and council interpretations during rollout. Some firms estimate relief might be moderate rather than transformative, particularly for high-risk assets.

Implementation Challenges & Risks

While the proposals signal a lighter regulatory footprint, the transitional details will matter greatly. Property stakeholders are watching closely how legacy contracts, financing clauses tied to seismic ratings, and insurance obligations will be treated under the new regime. Some commentators note that removing the NBS metric may introduce legal ambiguity in existing lease or mortgage terms.

Overall, the proposed reforms mark a major transformation in New Zealand’s seismic safety regulations. For many listed property companies, success will hinge not just on headline savings but on how smoothly the new regime is implemented in practice—and how predictably councils apply it at ground level.
