Buying house insurance is one of the biggest financial decisions you will make as a homeowner - but the process can feel overwhelming. This guide walks you through everything you need to know, from understanding sum insured and natural disaster cover to comparing policies, avoiding common mistakes, and making sure you are properly covered before settlement day.
House insurance policies in New Zealand are not all the same. While they share a common purpose - covering the cost of repairing or rebuilding your home after damage - the details vary significantly between insurers. Understanding what to look for before you start comparing is the first step toward getting the right cover.
The most important thing to understand is what the policy actually covers. Most NZ house insurance policies cover damage from fire, storm, flood, earthquake, theft, vandalism, and accidental damage. But the specific events covered, the limits that apply, and the exclusions can differ. For a detailed breakdown, see our guide to what house insurance covers in NZ.
Exclusions are just as important as inclusions. Common exclusions across NZ house insurance policies include gradual damage (such as slow leaks, rot, or rust), damage from lack of maintenance, damage caused intentionally, and damage from pre-existing defects you knew about. Some policies also exclude certain types of retaining walls, fences, or outbuildings unless specifically listed. Always read the exclusions section before committing.
Check the excess structure carefully. Most policies have a standard excess (the amount you pay per claim), plus a separate natural disaster excess that is often significantly higher. Some insurers also apply different excesses for specific claim types such as water damage or theft. Our guide to insurance excess explains how the different types work and what to watch for.
Finally, look at how claims are handled. Does the insurer manage claims in-house or outsource them? Can you choose your own builder, or must you use the insurer's approved repairers? What is the process for emergency repairs? The Insurance Council of New Zealand (ICNZ) has consumer-friendly guidance on what to expect from the claims process.
One of the most important decisions when buying house insurance in NZ is whether your policy uses a sum insured model or full replacement cover. This determines how much the insurer will pay if your home needs to be rebuilt, and getting it wrong can be extremely costly.
Sum insured means you nominate a maximum amount - the most the insurer will pay to rebuild your home. If the actual cost of rebuilding exceeds your sum insured, you pay the difference out of your own pocket. Most NZ insurers have moved to a sum insured model in recent years, largely in response to the Canterbury earthquakes which exposed the financial risks of open-ended replacement cover.
Full replacement cover means the insurer pays whatever it costs to rebuild your home to the same standard, without a dollar cap. Very few NZ insurers still offer full replacement policies for standard residential homes, though some policies marketed as "sum insured" include a buffer of 10% to 20% above the nominated amount.
If your policy uses sum insured, it is critical to get the amount right. Setting it too low means you are underinsured and may not receive enough to rebuild. Setting it too high means you are paying more in premiums than necessary. The ICNZ sum insured information page explains the concept and the risks of getting it wrong.
To estimate your rebuild cost, you can use online calculators provided by some NZ insurers, or engage a registered quantity surveyor for a more precise figure. The rebuild cost is not the same as the market value of your home - it is the cost of physically rebuilding the dwelling from scratch, including demolition, site clearance, consents, and professional fees. Settled.govt.nz has useful guidance on understanding rebuild costs for NZ homes.
Review your sum insured at every renewal. Building costs in New Zealand have increased significantly in recent years due to materials shortages, labour costs, and regulatory changes. A sum insured figure that was adequate three years ago may be well short of what it would actually cost to rebuild today.
New Zealand sits on the Pacific Ring of Fire, making natural disaster cover a critical part of any house insurance policy. The government provides a base layer of natural disaster cover through what was formerly known as EQC (Earthquake Commission) and is now Toka Tu Ake, transitioning to the Natural Hazards Commission (NHC) framework.
If you have house insurance with a private insurer, you are automatically covered by this government natural disaster scheme. The levy is collected by your insurer and passed on. You do not need to arrange it separately. The cover applies to specific natural disasters - earthquake, natural landslip, volcanic eruption, hydrothermal activity, and tsunami.
The government scheme covers the first $300,000 plus GST of dwelling damage from these events. Any damage above this cap is covered by your private insurer (up to your policy's sum insured or cover limit). This means your private house insurance is essential for full protection - the government scheme alone is not enough for most NZ homes.
It is worth understanding what the government scheme does not cover. Flood, storm, and fire damage are not covered - even if they occur during or alongside a natural disaster. These are covered by your private insurer. This is a common point of confusion. For a full breakdown, see our guide to EQC and natural disaster cover.
Since 2022, most natural disaster claims are managed by your private insurer on behalf of the government scheme. This means you deal with one point of contact rather than separate agencies - a significant improvement on the process experienced by Canterbury earthquake claimants.
When buying house insurance, check the natural disaster excess on each policy. This is typically much higher than the standard excess - often $2,500 or more - and varies between insurers. The Natural Hazards Commission website has detailed information about the current scheme and how it works alongside private insurance.
Buying house insurance in NZ is straightforward once you know what you need. Whether you are a first-home buyer arranging cover before settlement or an existing homeowner switching providers, the process follows the same basic steps.
Step 1: Gather your property details. You will need the property address, the year it was built, the construction type (timber, brick, concrete block, etc.), the roof material, the number of storeys and approximate floor area, any recent renovations, and your estimated sum insured (rebuild cost). If you are buying a property, much of this information will be in the building report or the listing details.
Step 2: Estimate your rebuild cost. If your policy is sum insured (most NZ policies are), you need to nominate a maximum rebuild amount. Use an online calculator from an NZ insurer, or for more accuracy, get a rebuild cost estimate from a registered quantity surveyor. Remember that rebuild cost is not the same as market value - it is what it would cost to physically rebuild the dwelling.
Step 3: Get estimates from multiple providers. Use Compare.org.nz to see estimated premiums from a range of NZ insurers side by side. This gives you a starting point for understanding the market. From there, visit individual insurers' websites to request actual quotes with precise pricing for your property.
Step 4: Compare the details. Look beyond the headline premium. Compare the excess (both standard and natural disaster), the sum insured or cover limit, what is included and excluded, any optional extras (such as glass cover or temporary accommodation), and how the insurer handles claims.
Step 5: Read the policy wording. Download the full policy document for your shortlisted options. Check the exclusions, the conditions you must meet, and the claims process. If anything is unclear, contact the insurer directly.
Step 6: Purchase and confirm cover. Buy your policy online, over the phone, or through a broker. Make sure you receive written confirmation of cover, including your policy number, start date, and the full policy wording. Keep these documents somewhere accessible.
From gathering your details to confirming cover in six steps
Comparing house insurance purely on premium is one of the most common mistakes NZ homeowners make. Two policies at the same price can offer very different levels of protection. Here is what to focus on when you are evaluating your options side by side.
Excess levels. Check both the standard excess and the natural disaster excess. A policy with a $500 standard excess and a $2,500 natural disaster excess will cost you significantly more out of pocket in a claim than one with $250 and $1,000 respectively. Factor in the excess when comparing the true cost of each policy.
Sum insured and any buffer. Some policies include a buffer above your nominated sum insured - typically 10% to 20% - to account for cost overruns during a rebuild. Others pay strictly up to the nominated amount with no additional margin. If building costs spike after a widespread event (as happened after the Canterbury earthquakes), that buffer could make a significant difference.
Included extras. Some NZ house insurance policies include temporary accommodation, emergency repairs, professional fees (architects, engineers), demolition and site clearance, and gradual damage cover (limited) as standard. Others charge extra for these or do not offer them at all. Check what is included before you compare headline prices.
Optional add-ons. Common add-ons for NZ house insurance include cover for swimming pools, retaining walls, fences, driveways, and landscaping. If your property has these features, check whether they are covered under the base policy or require separate additions.

Two policies at the same premium can offer very different protection
Buying your first home is exciting - and there is a lot to juggle. House insurance often gets left until the last minute, which is when mistakes happen. These are the most common ones first-home buyers in NZ make, and all of them are avoidable.
Leaving insurance until the last minute. In New Zealand, you typically need house insurance in place before settlement day. Your bank or mortgage provider will almost certainly require it as a condition of lending. Leaving it until the day before settlement creates unnecessary stress and limits your ability to compare options. Start the process as soon as your offer is accepted.
Confusing market value with rebuild cost. The price you pay for a house is not the same as what it would cost to rebuild. The market value includes the land, while the rebuild cost is purely the physical construction. First-home buyers often set their sum insured based on the purchase price, which can lead to either underinsurance or overinsurance. Use a rebuild cost calculator or get a professional estimate.
Not understanding EQC/natural disaster cover. Many first-home buyers assume they are automatically covered for everything, or do not realise that the government natural disaster scheme has a cap of $300,000 plus GST for the dwelling. If your rebuild cost exceeds this, the balance is covered by your private insurer - which is why getting your sum insured right is so important. See our EQC guide for the full picture.
Choosing the cheapest policy without reading the details. When you are already stretching your budget for a deposit, it is tempting to go for the lowest premium. But a cheaper policy often means higher excesses, fewer inclusions, or more restrictive conditions. A few hundred dollars saved on premiums can cost tens of thousands if the cover falls short when you need it.
Not disclosing known issues. If you know about pre-existing damage, a leaky roof, or a property that has had previous insurance claims, you must disclose this. Non-disclosure is a common reason claims are declined. The Financial Markets Authority (FMA) has guidance on your duty of disclosure as a policyholder.
Forgetting about contents insurance. House insurance covers the dwelling - the physical structure. Your belongings inside the house are covered by contents insurance, which is a separate policy. Many first-home buyers focus on the house and forget to arrange contents cover, leaving their furniture, electronics, and personal items unprotected.
The Settled.govt.nz insurance guide for home buyers walks through the insurance steps in the context of the overall home-buying process and is a useful resource for anyone purchasing their first property.
If you are buying an apartment, townhouse, or unit title property in New Zealand, the insurance situation is different from a standalone house. In most cases, the body corporate (also called the owners' corporation) arranges insurance for the building structure as a whole. Individual unit owners are then responsible for insuring their own contents and any fixtures or fittings that are not part of the common property.
Under the Unit Titles Act 2010, the body corporate is required to insure the building for its full replacement value. This means you do not need to arrange your own house insurance for the structure. However, you should check exactly what the body corporate policy covers and what it does not.
Common gaps in body corporate insurance include fixtures and improvements you have made to your unit (such as a new kitchen or bathroom), contents (your personal belongings), and liability cover for damage you cause to common property. You may need a separate unit owner's policy - sometimes called a unit title policy or owner's contents policy - to fill these gaps.
Before buying an apartment, ask to see the body corporate's insurance policy, including the sum insured, the excess, and any exclusions. Check whether the levy you pay to the body corporate includes the insurance cost. The Settled.govt.nz guide to buying an apartment has practical information on what to check.
Body corporate insurance premiums can vary significantly depending on the building's age, construction type, location, and claims history. In some cases - particularly for older buildings in high-risk earthquake zones - the cost of body corporate insurance has increased substantially, and this flows through to the levies unit owners pay. This is worth factoring into your budget when considering an apartment purchase.
