The type of house insurance you hold - replacement or indemnity - determines how much you receive if your home is seriously damaged or destroyed. The gap between the two can run into hundreds of thousands of dollars. This guide explains what each means in practice, with real payout examples, so you can see exactly what's at stake.
These two terms describe how your insurer calculates the payout if your home is damaged or destroyed. They sound technical, but the core difference is straightforward - and it matters enormously when a claim happens.
Replacement value (sometimes called full replacement or sum insured cover) means your insurer will pay to repair or rebuild your home to a similar standard as it was before the damage occurred, up to the sum insured you have nominated. If your house burns down, the insurer pays what it actually costs to rebuild it - including meeting current New Zealand Building Code requirements. This is the most common type of house insurance in NZ, and what most banks require if you have a mortgage.
Indemnity value means your insurer pays based on the current market value of the building at the time of the loss, accounting for its age, wear, and overall condition. It effectively factors in depreciation. A 40-year-old weatherboard home with original fittings and an ageing roof would be valued as exactly that - not as a brand-new build. The payout reflects what the home was actually worth in its deteriorated state, not what it would cost to rebuild from scratch.
The gap between the two can be staggering. A home that costs $550,000 to rebuild might only have an indemnity value of $250,000 to $350,000, depending on its age and condition. That is a shortfall of $200,000 or more that the homeowner would need to cover themselves.
For a broader overview of house insurance cover, see our guide to what house insurance covers in NZ. The Sorted.org.nz house insurance guide also explains the fundamentals well.
The easiest way to understand the difference is through a practical example.
Imagine a three-bedroom weatherboard home in Hamilton, originally built in 1985. The owners have maintained it reasonably well, but the kitchen and bathroom are original, the roof has about five years of life left, and the wiring was last updated in the early 2000s. A fire destroys the home completely.
Under a replacement value policy, the insurer would pay the cost to rebuild the home to a similar standard - a new three-bedroom house on the same site, meeting the current Building Code. In 2026, that rebuild might cost $500,000 to $600,000 depending on the size, location, and construction costs at the time. The payout goes up to the nominated sum insured.
Under an indemnity value policy, the insurer would assess what the home was worth immediately before the fire, factoring in its 40-year-old kitchen, ageing roof, and overall wear. The payout might be $250,000 to $350,000 - reflecting the home's depreciated condition, not the cost to build a new one.
That difference - potentially $200,000 to $300,000 - is the gap between being able to rebuild your home and being left with a significant shortfall. For many homeowners, this gap only becomes apparent at claim time, which is exactly when it's too late to do anything about it.
The Consumer NZ house insurance guide highlights this distinction as one of the most important things to understand before purchasing a policy.
The table below shows indicative payout differences for a home with a current rebuild cost of $550,000. These are estimates only - actual indemnity valuations vary depending on location, construction type, maintenance history, and the insurer's assessment. But they illustrate how depreciation can dramatically reduce an indemnity payout as a home ages.

| House Age | Condition | Replacement Payout (up to sum insured) | Indemnity Payout (estimated) | Shortfall |
|---|---|---|---|---|
| 5 years | Near-new condition | Up to $550,000 | $480,000 - $520,000 | $30,000 - $70,000 |
| 15 years | Good condition, some wear | Up to $550,000 | $370,000 - $430,000 | $120,000 - $180,000 |
| 25 years | Original kitchen/bathroom, sound structure | Up to $550,000 | $280,000 - $350,000 | $200,000 - $270,000 |
| 40 years | Dated fittings, roof nearing end of life | Up to $550,000 | $200,000 - $280,000 | $270,000 - $350,000 |
| 60+ years | Character home, significant deferred maintenance | Up to $550,000 | $120,000 - $200,000 | $350,000 - $430,000 |
| 80+ years | Heritage villa, original features, some deterioration | Up to $550,000 | $80,000 - $160,000 | $390,000 - $470,000 |
Key point: The older the home, the wider the gap. For newer homes in good condition, the difference may be manageable. But for homes over 25 years old - which describes a large proportion of the NZ housing stock - the shortfall under an indemnity policy can be devastating.
According to Stats NZ data, a significant share of New Zealand's housing stock was built before 1990, meaning many Kiwi homeowners are living in properties where the gap between replacement and indemnity value is substantial.
Both cover types have legitimate uses, but the trade-offs are significant. Here's how they compare across the factors that matter most to NZ homeowners.
How the two house insurance cover types compare in New Zealand
Despite its drawbacks, indemnity cover does have a place. There are specific situations where it may be a practical choice - or in some cases, the only option available.
Older homes that are difficult to insure on a replacement basis. Some insurers will not offer replacement cover for very old homes - particularly pre-1940s villas, heritage properties, or homes with significant deferred maintenance. The cost of rebuilding these homes to their original standard (or even to modern code) is often extremely high and difficult to estimate accurately. In these cases, indemnity may be the only cover available from some insurers.
Character homes and heritage properties. New Zealand has thousands of character homes - Victorian and Edwardian villas, Arts and Crafts bungalows, and other period homes. Rebuilding these with traditional materials and methods (native timber framing, lead-light windows, ornate plasterwork) can cost significantly more than a standard modern build. Some owners opt for indemnity cover because the replacement cost would be prohibitively high, or because they don't intend to rebuild a replica if the home is destroyed.
Properties where the land value dominates. In some parts of Auckland, Wellington, and other high-value areas, the land may be worth $800,000 or more while the building itself is a modest older home. If the home were destroyed, the owner might choose to build something new rather than replicate the existing structure. Indemnity cover may be seen as adequate because the building is not the primary asset.
Investment properties near the end of their useful life. Landlords with older rental properties that are approaching the end of their economic life sometimes choose indemnity cover to keep costs down. The calculation is that the property is likely to be demolished and redeveloped within the next few years anyway.
Homes with known issues. Properties with pre-existing problems - such as those affected by weathertightness issues (leaky building syndrome), unconsented work, or non-compliant construction - may only be offered indemnity cover by some insurers. The risks associated with replacement are too uncertain for the insurer to commit to a full rebuild.
The Insurance Council of New Zealand (ICNZ) has consumer resources explaining the different types of house insurance available, including situations where cover options may be limited.
Indemnity cover is cheaper for a reason. It transfers more risk to the homeowner, and that risk can be significant. Here are the main dangers to be aware of.
The depreciation gap can be enormous. As the payout table above shows, the shortfall between an indemnity payout and the actual cost to rebuild can be $200,000 to $400,000 or more for older homes. Most homeowners do not have that kind of money sitting in reserve. Without it, they may be unable to rebuild.
Building Code compliance costs are not covered. When a home is rebuilt in New Zealand, it must comply with the current Building Code - not the code that applied when the original home was built. This often means upgraded insulation, modern wiring, seismic bracing, and other improvements that add significant cost. Under a replacement policy, these costs are typically covered. Under an indemnity policy, they are not - because the payout is based on the value of the old home, not the cost of building a compliant new one.
You may not be able to rebuild at all. If the indemnity payout is not enough to cover the rebuild cost, and you don't have savings to bridge the gap, you could be left with a cleared section and not enough money to build on it. This was a real outcome for some Christchurch homeowners after the 2010-2011 earthquakes.
The valuation process can be contentious. Indemnity payouts require the insurer to assess the home's value at the time of the loss - a process that involves judgement calls about condition, remaining life, and depreciation. Homeowners frequently disagree with their insurer's assessment, and disputes can take months or years to resolve through the Insurance and Financial Services Ombudsman (IFSO) or the courts.
Mortgage complications. Most mortgage lenders require replacement cover. If you switch to indemnity without telling your bank, or if your insurer shifts you to indemnity at renewal (which can happen), you may be in breach of your loan agreement. This gives the bank the right to require you to take out replacement cover or, in extreme cases, call in the loan.
The Christchurch earthquakes provided a stark illustration of these risks. The interest.co.nz insurance section covered many cases where the difference between replacement and indemnity cover had life-changing consequences for homeowners.
The distinction between replacement and indemnity value has been tested in New Zealand courts multiple times, particularly in the wake of the Canterbury earthquakes. Several key principles have emerged.
The principle of indemnity is foundational. Under New Zealand insurance law, insurance is a contract of indemnity - meaning the purpose is to put the policyholder back in the same position they were in before the loss, not to leave them better off. However, replacement value policies modify this principle by promising to pay the cost of reinstatement, which may be higher than the home's depreciated value. Courts have upheld that replacement policies genuinely do pay more than strict indemnity.
Policy wording is paramount. NZ courts have consistently held that the specific wording of the policy determines the cover provided. If the policy says "indemnity value" but doesn't clearly define how depreciation is calculated, disputes arise. The Courts of New Zealand have dealt with numerous cases where vague wording led to disagreements over payout calculations.
The Christchurch earthquake cases. The Canterbury earthquake sequence generated a large volume of insurance litigation. Key disputes included whether replacement policies should cover the cost of meeting updated Building Code requirements, whether "as new" meant literally new construction or just functional equivalence, and how to value homes that were damaged but not destroyed. The Settled.govt.nz website (now part of the Greater Christchurch Claims Resolution Service) provides background on how many of these claims were resolved.
Betterment and the new-for-old question. One recurring legal issue is whether a replacement payout that results in a better home than the one that was lost constitutes "betterment" - meaning the homeowner has been put in a better position than before. Courts have generally held that meeting current Building Code requirements is not betterment, because the homeowner has no choice but to comply with the code. However, upgrades beyond code compliance may be treated differently.
The Fair Insurance Code. The Fair Insurance Code, administered by ICNZ, sets out standards of practice for insurers. It requires clear communication of policy terms and fair claims handling. If an insurer has not clearly explained the difference between replacement and indemnity cover, this can be relevant in a dispute. For more on how insurance disputes work, see our guide to complaining about an insurer.
These legal cases reinforce a consistent message: read and understand your policy wording before you need to make a claim. The time to discover you have indemnity cover is not after your home has been destroyed.
Not all replacement policies are created equal, and the specific wording in your policy document (the Product Disclosure Statement, or PDS) determines exactly what you're entitled to. Here are the key things to check.
Check whether your policy is replacement or indemnity. This sounds obvious, but some homeowners don't actually know which type of cover they have. The PDS should state clearly whether the basis of settlement is replacement/reinstatement or indemnity. If it's not obvious, contact your insurer and ask directly.
Look for the sum insured cap. Most replacement policies in NZ are "sum insured" policies, meaning the insurer will pay up to the amount you have nominated. If your sum insured is $450,000 but the actual rebuild costs $600,000, you bear the $150,000 shortfall. Getting your sum insured right is critical - see our guide to calculating your sum insured for help with this.
Understand the reinstatement wording. Some policies say they will rebuild "to a condition substantially the same as when new." Others say "to a similar condition as immediately before the loss." These phrases mean different things. The first is closer to full replacement; the second may factor in the home's pre-loss condition.
Check for Building Code compliance cover. A good replacement policy explicitly covers the cost of complying with the current Building Code when rebuilding. Some policies include this as standard; others treat it as an add-on or cap it at a percentage of the sum insured. This can add tens of thousands of dollars to a rebuild cost.
Look for the indemnity settlement option. Some replacement policies include a clause allowing the insurer to settle on an indemnity basis in certain circumstances - for example, if you choose not to rebuild. If you take a cash settlement instead of rebuilding, the insurer may pay indemnity value rather than full replacement cost. This is common and legal, but it's worth knowing before it happens.
Watch for policy changes at renewal. Insurers can change the terms of your policy at renewal. In rare cases, a home that was previously on replacement cover may be moved to indemnity - particularly if the insurer has reassessed the risk or the home has deteriorated. Always read your renewal documents carefully.
Understand excess and Natural Hazards Commission (NHC) interactions. Your excess applies to your private insurance claim, while NHC (formerly EQC) cover has its own excess for natural disaster claims. The two interact in ways that can affect your total out-of-pocket cost. See our guide to EQC for details on how this works.
