House insurance, what it actually covers

House insurance covers the building and the things around it, like fences and the garage. Nearly every claim that goes wrong in New Zealand comes down to one of three things. The sum insured was too low. Something was not told to the insurer. Or the damage happened slowly instead of all at once. This page covers all three.

What kind of home is it?

The short version

Five things that decide how a house policy behaves

  • The sum insured is a rebuild cost, not a value. It is what it would cost to rebuild your house as it is now. That includes knocking down what is left, clearing the site, and paying architects and engineers. It is not what the house would sell for. It is not the council rating value. It is not your mortgage. Those are four different numbers. Only one of them pays a claim.
  • The homeowner sets it, not the insurer. New Zealand switched to sum insured policies after the Canterbury earthquakes. Insurers give you a calculator and will accept a valuation. But the number on your policy is yours, and it is the most the policy will pay.
  • Natural hazard damage has two layers. The Natural Hazards Commission Toka Tลซ Ake pays the first chunk of natural hazard damage to your home, and some damage to the land. Your own policy sits on top of that. Your insurer collects the levy and handles the claim, so from the outside it looks like one policy.
  • Sudden is covered, gradual usually is not. A pipe that bursts is a sudden event. A pipe that has dripped behind a wall for two years is not. Most policies have a small exception for hidden leaks from water pipes. It is narrower than people expect.
  • What was not disclosed can undo the rest. Past claims. Building work. Consents that were never signed off. Times the house sat empty. Insurers want to know all of it. A claim can be cut back or turned down because of an answer you gave when you took the policy out.

Ratings are curated from a number of sources, including Google, Feefo and Trustpilot. They may not be completely up to date. They measure what reviewers said about dealing with a company, which is not the same thing as what its policy covers, and a brand shown as not rated is one we hold no reviews for rather than one that scored badly.

Highly rated rows appear first and are marked. Every other brand is listed alphabetically. Nothing in this table is ordered by how good the cover is, and no figure here is our assessment of any insurer.

House insurance in New Zealand, on a weatherboard home with its roof, walls and fences insured as one building.

What you are insuring

The building, and everything fixed to it

House insurance covers the structure. That is the roof, the walls, the floors and the fittings attached to them, along with the fences, decks, driveways and paths around it.

What it does not cover is anything you would take with you. Furniture, appliances and clothing belong on a contents policy, which is a separate product and outside what this site covers.

What is insured

The building, and the things attached to it

A house policy covers the house itself and everything fixed to it. The roof, the walls and floors, the wiring and pipes inside them. The kitchen and bathroom fittings that are attached rather than free-standing. It usually covers the built things around the house too. Fences, decks, garages, carports, sheds, driveways, paths, retaining walls and in-ground pools. A lot of value hides in that list.

Those outside structures matter more than they look. They are the part people forget when working out a sum insured. A long driveway on a slope. Retaining walls. A full boundary of fencing. Together they can be a big share of what it costs to put a property back. None of it comes to mind when you are picturing the house.

The other thing people miss is the cost of the rebuild itself, not the building. Clearing the damaged site. Getting rid of the rubble. Paying architects, engineers and consent fees. Those are real costs, and they come out of the same sum insured as the house.

The events

What a house policy generally responds to

Policies cover sudden, accidental damage from a set list of events. Below is what New Zealand house policies usually include. Every policy is a bit different, and the document you are given is the one that pays your claim.

Fire, smoke and explosion

The oldest risk there is, and still the one that destroys whole houses. Smoke damage without flames is usually covered too, though not always to the same extent.

Storm, wind and flood

Sudden weather. If a property has flooded before, or sits in a known flood zone, the cover on offer can narrow a lot. That is why you get asked at quote time.

Earthquake and natural hazards

Shared with the Natural Hazards Commission. Your insurer collects the levy, takes the claim and runs it, so you only deal with one company.

Burst pipes and sudden water escape

Water bursting out is covered. Water slowly seeping is not, though most policies have a small hidden leak benefit with its own limit.

Impact and vandalism

Cars, falling trees, aircraft and vandalism. Vandalism cover is one of the first things to shrink once a home is rented out or empty.

Alternative accommodation

Somewhere else to live while your home cannot be lived in. There is a dollar limit and a time limit.

The number this site will not give you

Where a sum insured comes from

This site publishes no rebuild costs and no sum insured figures, and it does not guess at one. A number produced without seeing your house is just a guess. Acting on a guess is how people end up underinsured. Every big New Zealand insurer has a free rebuild calculator, and most use the same cost data. For anything out of the ordinary, get a valuation instead. That means older homes, unusual construction, hard access, heritage features, or a lot of retaining. A registered valuer or a quantity surveyor gives you a figure you can stand behind.

Two layers

How the Natural Hazards Commission fits underneath

What the Commission covers

Natural hazard cover in New Zealand runs through the Natural Hazards Commission Toka Tลซ Ake. It used to be called EQC. Cover applies automatically to any house with private fire insurance. Your insurer collects the levy inside your premium, so there is no separate bill.

The Commission pays the first chunk of natural hazard damage to the house. It also covers some damage to the land right around it. Land matters, because your own policy usually does not cover it at all.

What the insurer covers

Damage above the Commissionโ€™s cap is your insurerโ€™s to pay, up to your sum insured. You only make one claim. Your insurer sorts out both parts, so the split is their paperwork rather than yours.

The caps, the land rules and the levy are set by law and they change. That is why they are not listed here. The Commission publishes the current ones at nhc.govt.nz.

What happens

How a house insurance quote is put together

  1. 01

    The property is identified

    Address, year built, floor area, number of storeys, and what the walls and roof are made of. Insurers can look a lot of this up and often fill it in for you. The answers you confirm are the ones that count.

  2. 02

    The risk is assessed against underwriting rules

    Behind the form is a set of rules. Flood and earthquake risk. How close to the coast. What it is built of. How easy it is to reach. How old it is and what condition it is in. Those rules decide whether you get a price straight away, get sent to a person, or get turned down.

  3. 03

    History is disclosed

    Past claims at the address. Any cover that has been turned down or cancelled. Building work, and whether it was consented. Damage that is already there. This is the part where later claim arguments usually start.

  4. 04

    A sum insured is set

    You give them the figure, usually after running their rebuild calculator or getting a valuation. It caps what the building claim can pay. It is worth another look at every renewal.

  5. 05

    Excess and options are chosen

    A bigger excess usually means a lower premium. Natural hazard claims often have their own separate excess. Optional extras differ between insurers and are priced one by one.

Where it goes wrong

Three ways a house claim gets reduced

These are the recurring patterns rather than an exhaustive list, and how any individual insurer responds depends on their wording and the facts.

The sum insured was set once and never revisited

A figure that was fine when you took the policy out can fall a long way behind. Building costs rise. You renovate. You add a deck and a garage and never update the number. The sum insured is a ceiling, so the gap only shows up when the house is destroyed. That is the worst possible moment to find out.

What happens:The policy pays to its limit and the shortfall sits with the homeowner.

The damage turned out to be gradual

Rot behind a shower. A slow leak inside a wall. Corrosion that built up over years. None of that is a sudden event. Most policies have a small hidden leak benefit for water pipes. It has its own low limit and its own conditions.

What happens:Cover is limited to the gradual damage benefit, where the policy has one at all.

Something material was not disclosed

Building work without consent. A past claim. A stretch where the house sat empty. A drainage problem you knew about. The Contracts of Insurance Act 2024 changed how this duty works for everyday policies. The basic point has not changed. An insurer prices what it was told.

What happens:A claim can be reduced, or the policy treated as if it had never been on risk.

None of this is a prediction about your policy. What an insurer can actually do is set out in the policy document. For everyday policies it is also limited by the Contracts of Insurance Act 2024 and the Fair Insurance Code.

Who writes it

Insurers writing house cover in New Zealand

Listed A to Z. The order means nothing and we do not rank insurers. Cove is the brand we refer people to, and we say so on every page.

Cover and limits differ between these insurers, and they change. Nothing here says any of them is better or cheaper than another.

FAQ

House insurance questions

Is the sum insured the same as what the house is worth?

No, and they are commonly a long way apart. The sum insured is the cost of rebuilding the house as it stands, including demolition, site clearance and professional fees. Market value includes the land and reflects what a buyer would pay, which is driven by location as much as by the building. A rating valuation is a third number again, produced for council rating purposes on a mass-appraisal basis. Only the rebuild cost is relevant to a building claim.

Who decides the sum insured on a New Zealand house policy?

The homeowner does. New Zealand moved away from open-ended replacement cover after the Canterbury earthquakes, and policies are now written to a stated sum insured. Insurers make rebuild calculators available and will accept a valuation from a registered valuer or a quantity surveyor, but the figure that appears on the policy schedule is the policyholderโ€™s, and it is the maximum the building side of the policy will pay.

Does house insurance cover the contents of the house?

No. A house policy covers the building and the structures fixed to the property. Furniture, appliances, clothing, electronics and other belongings are covered by a separate contents policy, which is a different product with its own sum insured. Many insurers sell the two together and bundle the administration, but they remain two policies with two limits.

What does the Natural Hazards Commission cover that a private insurer does not?

The Commission covers a first portion of natural hazard damage to a home, and it also covers some of the land around it, which private house policies generally exclude entirely. Cover is automatic for any home carrying private fire insurance, and the levy is collected by the insurer within the premium. Above the Commissionโ€™s cap, the private policy responds up to the sum insured. Current caps and land cover rules are set by legislation and published at nhc.govt.nz.

Is a leak that has been happening for years covered?

Usually not as ordinary damage, because insurance responds to sudden and accidental events rather than to deterioration. Many New Zealand wordings do include a limited hidden gradual damage benefit for water escaping from pipes inside the building, typically with its own limit and conditions such as a requirement that the leak was not reasonably detectable. Whether a particular leak falls inside that benefit turns on the wording and the facts.

Does unconsented building work affect a house policy?

It can. Unconsented or uncertified work is something a prudent insurer would generally want to know about, so it falls within the disclosure duty, and some wordings exclude or limit cover for damage arising out of the non-compliant work itself. Insurers vary in how they treat it, and a great deal depends on the nature of the work. Disclosing it at quote time is what preserves the position either way.

What happens to house insurance between selling and settlement?

Cover through the period between signing and settlement is a question the sale and purchase agreement addresses, and the standard agreement used in New Zealand allocates risk between the parties. In practice both a seller and a buyer commonly hold cover across that window. It is a point worth confirming with the solicitor handling the conveyance rather than assuming, because the answer depends on the terms of the particular agreement.

Does the excess apply once, or once per event?

Excesses generally apply per claim event rather than per policy period, so two unrelated events in a year usually attract two excesses. Many policies also apply a separate, and often larger, excess to natural hazard claims, and some apply specific excesses to particular perils or to properties with certain characteristics. The schedule issued with a policy lists the excesses that apply to it.

Disclaimer

General information only. Not personalised financial advice.

Home insurance is one of the few contracts most households hold for decades and read once. What a policy covers, what it excludes, and what has to be disclosed before it starts all vary between insurers and between versions of the same product, and the wording is what settles a claim. This site explains how the cover generally works so those conversations start from a better place. It is not a substitute for the policy document.

What this site is

An information site about insuring a home in New Zealand. Not an insurer, not a broker, not a registered financial adviser. Nothing here is personalised financial advice or a recommendation about any particular property.

What this site does not do

It publishes no premiums, no rebuild costs and no sum-insured figures, and nothing here estimates one. Those numbers come from an insurer's own calculator or a registered valuer, and getting them wrong is what underinsurance is made of.

What the insurer decides

Whether cover is offered, on what terms, at what price and with what exclusions is decided by the insurer, on the information given to them about the specific property.

Our relationship with Cove

This site refers people to three insurance brands. Cove for most homes, FMG for farms and lifestyle blocks, and AA Insurance for apartments. We receive no commission, fee or payment for any of those referrals, and nothing on this site is sold. No brand can buy a position, a badge or a mention. We are not an insurer, not a broker, and not a registered financial adviser. Nothing here is a recommendation that any brand is right for any particular home. Full disclosure on the partner page.

The policy wording decides

Every description of cover on this site describes what that type of cover generally does, not what any particular policy does. Limits, excesses, exclusions and conditions differ between insurers and change between versions, and the wording issued with a policy is the document that settles a claim.

Important information

About this site, what it does not do, and your protections.

Last reviewed 1 September 2026.

1. What this site is

Homeinsurance.org.nz is an information site about insuring a home in New Zealand. We are not an insurer, not a broker, and not a financial adviser. We do not arrange, sell or underwrite insurance. We do not hold your money. We do not give regulated financial advice, as defined by the Financial Markets Conduct Act 2013 Part 6 and the Financial Services Legislation Amendment Act 2019. Nothing here is advice about your situation.

2. No premiums, no rebuild costs, no sum insured

This site publishes no prices, no rebuild costs and no sum insured figures, and nothing here guesses at one. A sum insured is what it would cost to rebuild one particular house. That number comes from an insurerโ€™s calculator, or from a valuer who has seen the building. Where we explain what a sum insured is, we are explaining the idea. We are not giving you a figure.

3. The quote starter

The tool names a cover type based on how a home is used. It is not a quote. It is not an application. It does not mean cover is available or will be offered. Your answers stay in your browser and are not sent anywhere.

4. General information, not advice

Everything here is general information. It does not take account of your situation, your goals or your property. For a decision about cover, a licensed financial adviser or an insurance broker is the safer place to go. That is especially true if a property has past claims, a flood or earthquake risk, or building work that never got consent.

5. What the policy wording decides

When we describe cover, we describe what that kind of cover usually does. Limits, excesses, exclusions and conditions differ between insurers, and between versions of the same product. The document issued with your policy is the one that settles your claim. Where this site and that document disagree, the document wins.

6. Our relationship with Cove

Cove is the one brand we refer people to. We get no commission, fee or payment for it. No insurer pays us for a mention, a position or a write-up anywhere here. We do not claim Cove is the cheapest or the best cover for any home. Other insurers are described on their merits. This site is not independent, because it has one named partner, and we do not call ourselves independent. The full story is on our partner page. Cove is a brand, not an insurer. Its own documents name the company that carries the risk.

7. Privacy and personal information

Under the Privacy Act 2020, we run no forms and collect nothing about you. Your quote starter answers stay in your browser. They are never sent to a server we control. We use Google Analytics 4 to count visits, which tells us nothing about you personally. Click through to an insurer and you leave our site. From that point their privacy policy applies.

8. Duty of disclosure

New Zealand law says you have to tell an insurer the things they would want to know. The Contracts of Insurance Act 2024 changed how that works for everyday policies. A claim can be cut back or turned down over something you did not mention at the start. Building work, past claims, and stretches where the house sat empty are the usual ones. What any particular insurer needs is a question for them.

9. Fair dealing posture

This site follows the fair dealing rules in the Financial Markets Conduct Act 2013 Part 2 and the Fair Trading Act 1986. We also follow the Fair Insurance Code. We do not mislead, make things up, or state claims we cannot back. Facts and figures are either hedged or linked to the source. Those sources are the Natural Hazards Commission Toka Tลซ Ake, MBIE, Stats NZ, the Reserve Bank of New Zealand, the Insurance Council of New Zealand, Tenancy Services, the Commerce Commission and the Financial Markets Authority.

10. Complaints

We do not sell insurance, so we cannot deal with a complaint about a policy. Take it to your insurer first. If they do not fix it, take it to their complaints scheme. Most New Zealand insurers belong to the Insurance & Financial Services Ombudsman, which is free and independent.

11. Limitation of liability and governing law

As far as New Zealand law allows, Homeinsurance.org.nz and the people who run it are not liable for any loss or damage from using this site, or from relying on anything on it or linked from it. That covers direct and indirect loss. These terms are governed by New Zealand law, and any dispute goes to a New Zealand court.

Long form: terms, privacy, footer disclaimer.
