New Zealand replaced its decades-old earthquake insurance legislation in 2023. The Natural Hazards Insurance Act brought a higher building cap, new land cover arrangements, and a clearer claims process. Here is what it all means in plain English.
The Natural Hazards Insurance Act 2023 (NHI Act) is the legislation that now governs how natural disaster insurance works for residential property in New Zealand. It replaced the Earthquake Commission Act 1993, which had been the framework for over 30 years.
The new Act came into force on 1 July 2024, following a comprehensive review of how NZ's natural disaster insurance system performed - particularly in the wake of the Canterbury earthquakes and subsequent events. The review found that while the system was fundamentally sound, significant improvements were needed to the building cap, land cover provisions, and how claims were handled.
Under the NHI Act, the government entity formerly known as the Earthquake Commission (EQC) was formally renamed Toka Tu Ake. While many New Zealanders still use the name EQC, the official name reflects the organisation's broader role and its bicultural identity. Toka Tu Ake continues to administer the Natural Hazards Fund, which pays for residential natural disaster claims.
The core principle remains the same - if you have private house insurance, you automatically get natural hazard cover through Toka Tu Ake for earthquakes, natural landslips, volcanic eruptions, hydrothermal activity, and tsunami damage. But the details of how that cover works, how much it pays, and how claims are managed all changed under the new Act.
The shift from the Earthquake Commission Act 1993 to the Natural Hazards Insurance Act 2023 brought several significant changes. Here is how the two pieces of legislation compare on the things that matter most to homeowners.
How the old and new legislation compare for homeowners
The table below summarises the most significant changes the NHI Act introduced. Each of these is covered in more detail in the sections that follow.
| Area | Under the Old EQC Act | Under the New NHI Act |
|---|---|---|
| Building cap | $150,000 + GST per dwelling | $300,000 + GST per dwelling |
| Land cover | Separate land cover assessed through its own process | Land cover redesigned with clearer criteria for residential land damage |
| Claims management | EQC managed claims directly (dual-handling with insurers) | Private insurers manage all claims on behalf of Toka Tu Ake |
| Excess | Separate EQC and private insurer excess could apply | Single excess set by your private insurer |
| Entity name | Earthquake Commission (EQC) | Toka Tu Ake (Natural Hazards Commission) |
| Apartments/unit titles | Complex arrangements; bodies corporate dealt with EQC separately | Simplified provisions with clearer body corporate processes |
| On-sold properties | Limited clarity on transferring claim rights | Clearer rules about obligations when properties change hands with open claims |
| Contents cover | $20,000 + GST | No change - remains $20,000 + GST |

One of the most significant changes under the NHI Act is the doubling of the building cap from $150,000 + GST to $300,000 + GST per dwelling. This was a long-awaited increase that reflected the reality of rising building costs in New Zealand.
Under the old EQC Act, the $150,000 cap had not kept pace with construction costs. After the Canterbury earthquakes, many homeowners found that the EQC cap covered only a fraction of their damage, leaving their private insurer - and in some cases the homeowner themselves - to cover a much larger portion. The gap between the EQC cap and actual repair costs was a major source of frustration.
The new $300,000 + GST cap means Toka Tu Ake covers a significantly larger share of natural disaster building damage before your private insurer needs to step in. For a claim costing $350,000 to repair, Toka Tu Ake would cover the first $300,000 (plus GST), and your private insurer would cover the remaining $50,000 up to your sum insured.
That said, the $300,000 cap still may not cover the full cost of major damage for many New Zealand homes. Average rebuild costs in cities like Auckland, Wellington, and Queenstown can easily exceed this amount. This is why adequate private house insurance remains essential - the Toka Tu Ake cover is a first layer, not a complete safety net.
The cap applies per dwelling. If you own a property with two separate dwellings (for example, a main house and a minor dwelling or granny flat), each dwelling may have its own $300,000 + GST cap, provided each meets the criteria under the Act.

Land cover was one of the most contentious and complex areas under the old EQC Act, particularly after the Canterbury earthquakes. Thousands of claims involved land damage - such as liquefaction, lateral spread, and land subsidence - and the assessment process was slow, confusing, and often disputed.
Under the old Act, land cover was assessed separately from building damage. There was a defined area of residential land that EQC covered, but the criteria were unclear in many situations. This led to lengthy disputes, particularly in Canterbury where entire suburbs experienced land damage that was difficult to categorise.
The NHI Act 2023 redesigned land cover to provide clearer criteria for what types of residential land damage are covered and how they are assessed. The Act defines the land that Toka Tu Ake covers in relation to the dwelling - essentially the land under and immediately surrounding the residential building, plus land necessary for access and essential services.
The new provisions aim to reduce the ambiguity that caused so many problems in Canterbury. However, land damage claims remain inherently complex because every property is different. If your land is damaged in a natural disaster, the assessment will consider the specific characteristics of your property and the nature of the damage.
For more detail on how land cover works under the new Act, the Toka Tu Ake website provides guidance on what land is covered and how assessments are carried out. The Settled.govt.nz website also has useful information on land-related property issues.
The NHI Act formalised the insurer-managed claims model that had been progressively introduced since 2022. Under this model, your private insurer is the single point of contact for all natural hazard claims - you no longer deal with Toka Tu Ake (EQC) directly.
This was a direct response to the problems experienced after the Canterbury earthquakes, where homeowners often had to navigate separate claims with both EQC and their private insurer. The dual process created confusion, delays, and inconsistent outcomes. Under the new system, your insurer handles everything.

How claims are handled from start to finish
An earthquake, volcanic eruption, natural landslip, hydrothermal event, or tsunami damages your residential property. Ensure everyone is safe and follow Civil Defence instructions.
Call your insurer's claims line. Do not contact Toka Tu Ake directly. Your insurer will lodge your claim and begin the process. Document all damage with photos and videos before any clean-up.
Your insurer arranges assessments, which may include engineers, building assessors, or geotechnical specialists depending on the nature and scale of the damage.
Your insurer determines whether the damage falls within the Toka Tu Ake cap ($300,000 + GST) or exceeds it. Claims within the cap are settled by your insurer on behalf of Toka Tu Ake.
For claims within the cap, your insurer manages repairs or pays the settlement using Toka Tu Ake funds. For claims exceeding the cap, your insurer covers the portion above $300,000 + GST under your private policy.
You pay one excess as set by your private insurer's policy. There is no separate Toka Tu Ake excess. This simplifies what you pay out of pocket compared to the old dual-excess system.
If you are unhappy with how your claim is handled, you can escalate it through your insurer's internal complaints process. If that does not resolve the issue, the Insurance and Financial Services Ombudsman (IFSO) can investigate disputes. For general guidance on your insurance rights, see our guide on EQC (Toka Tu Ake) explained.
Apartments and unit title properties presented unique challenges under the old EQC Act - and the Canterbury earthquakes exposed many of them. Bodies corporate had to deal with EQC separately from individual unit owners' private insurers, creating a complicated and often adversarial process.
The NHI Act 2023 introduced clearer provisions for how natural hazard cover applies to unit title properties. Key changes include:
The body corporate's insurer now manages the natural hazard claim for the building as a whole. Individual unit owners do not need to lodge separate building claims with Toka Tu Ake. This streamlines the process significantly, particularly for larger apartment complexes.
The $300,000 + GST cap applies per unit (dwelling) within the building, not per building. This means a 20-unit apartment building has up to $6 million + GST in Toka Tu Ake building cover (20 x $300,000), managed through the body corporate's insurer.
The Act also clarifies how common property (shared areas like lobbies, stairwells, and car parks) is treated under natural hazard cover. This was a grey area under the old legislation that caused significant disputes in Canterbury.
If you own an apartment or unit title property, it is worth checking with your body corporate to understand how your building's insurance is structured and how a natural hazard claim would be managed. The Consumer NZ website has useful information on body corporate insurance obligations.
Not everything changed under the NHI Act. Several core aspects of New Zealand's natural disaster insurance system remained the same:
The automatic cover principle is unchanged. If you have private house insurance, you automatically have natural hazard cover through Toka Tu Ake. You do not need to buy it separately or opt in.
The natural hazards covered remain the same - earthquakes, natural landslips, volcanic eruptions, hydrothermal activity, and tsunamis. The Act did not expand coverage to include floods or storms, which continue to be covered by your private insurer only.
The contents cap remains at $20,000 + GST for personal belongings damaged by natural hazards. This has not changed since the old EQC Act.
The levy system continues to operate in the same way. Your private insurer collects the natural hazard levy as part of your premium and passes it on to Toka Tu Ake. The levy funds the Natural Hazards Fund, which pays for claims.
The fundamental two-layer structure - Toka Tu Ake provides the first layer of cover, your private insurer covers costs above the cap - remains in place. The NHI Act improved the mechanics of how this works, but the basic architecture is the same.
