AMI house insurance review

AMI Home Plus can settle a fire claim without applying your sum insured at all, and a flood claim with it. Which one you get is printed on your policy schedule. This page explains how the wording works, and what it shares with State.

What kind of home is it?

Who AMI is, and who carries the risk

AMI is one of the oldest household insurance names in New Zealand. It is owned by IAG, the largest general insurer in the country, which also owns State and NZI and underwrites house policies sold under several bank brands.

That ownership is not a detail. It means the company that actually pays an AMI claim is the same company that pays a State claim, and it means the two wordings come out of the same place. The section further down sets out how similar they turn out to be.

This page describes the home half of the Home Plus wording. Home Plus is the more complete of the AMI house products, so the limits below are the higher ones AMI publishes, not the entry level. Contents is a separate policy and this site does not cover it.

Two settlement bases, and the one that ignores your sum insured

Your policy schedule, the page that lists your address and your cover, shows a basis of settlement. In the AMI wording it is either Sum insured replacement or Replacement, and the difference between them is large.

Under Sum insured replacement, the most AMI pays for a loss is your total sum insured. That is the ordinary New Zealand arrangement. You give the insurer a number and the number is the ceiling.

Under Replacement, that ceiling is lifted in one specific situation. Where the loss comes from fire or explosion, the fire is not caused by a natural hazard, and you repair or rebuild, the wording says the limit of your home sum insured does not apply. What applies instead is the replacement cost of the house up to the floor area shown on your schedule.

So on a Replacement policy the number that protects you against a house fire is not your sum insured. It is the floor area, in square metres, printed on your schedule. That is a far easier figure to check and a far easier figure to keep right, and it is one most people have never looked at.

The limits do not lift for anything else. A flood, an earthquake, a storm or a landslip is still capped by the sum insured on either basis, and so is a fire that a natural hazard started. The wording is precise about that, and the distinction matters, because the fires people worry about and the fires that follow an earthquake are treated differently.

Three sums insured, and what sits inside each

The AMI wording uses three separate figures and they are easy to confuse.

The home sum insured is the cost to rebuild the house. Sitting inside it, not on top of it, are three capped items. All retaining walls come to fifty thousand dollars. A permanently fixed swimming pool and its equipment comes to fifty thousand dollars. A bridge, culvert, permanent ford or dam comes to fifteen thousand dollars.

A special feature sum insured is what you get when one of those items is listed separately on your schedule with its own figure. Retaining walls over fifty thousand dollars, a pool over fifty thousand, a crossing over fifteen thousand, a wharf, pier, landing or jetty, and a cable car all have to be handled this way. If they are not on the schedule as special features, the caps above are what applies.

The total sum insured is the home sum insured, plus every special feature sum insured, plus all the automatic and optional benefits, unless a particular benefit says otherwise. It is the ceiling on the whole of the home part of the policy for one event.

This site publishes no rebuild figures and does not estimate one, because a wrong number is how people end up underinsured and a web page cannot see your house. Every large New Zealand insurer runs a free rebuild calculator, and a registered valuer will do the same job in person for a fee.

What is included as standard

These are the automatic benefits in the Home Plus wording, which means they are in the policy without being bought separately. The limit column gives the figure at this product level.

A larger limit is not the same as better cover. The clause behind the limit decides what the money can be spent on, and several of the clauses below are much narrower than their figures suggest.

AMIHome Plus Insurance, AMI1713-1 08/24: automatic benefits, what each covers, and the limit that applies
BenefitWhat it coversLimit
Natural hazard damageSudden accidental loss to the house from earthquake, flood, landslip and the other natural hazards.The gap above your Commission entitlementAMI pays the difference between what the Natural Hazards Commission owes and what the policy would pay. The Commission’s own excess is not covered.
Temporary accommodationSomewhere of a similar standard to live, for you, your partner, family living with you, and your pets.$30,000 per event, per dwellingMain residence only. It also pays when an authority orders you out because damage is coming, even before anything has happened.

Retaining wallsWalls holding back earth on the property.$50,000, inside the home sum insuredThis is a cap within your sum insured, not extra money. Listing the wall as a special feature with its own sum insured is what lifts it.
Swimming poolA permanently fixed pool and the equipment it needs, such as pumps.$50,000, inside the home sum insuredSame structure as retaining walls. A more expensive pool needs to be a special feature.

AMIHome Plus Insurance, AMI1713-1 08/24. Read from the AMI Home Plus and Contents Plus policy wording, AMI1713-1 08/24 on 1 September 2026. Limits are one part of a policy: a larger figure can sit beside a narrower trigger or a tighter exclusion, and the wording issued with a policy is what settles a claim.

How the excess comes off, which is not how most people assume

An excess is the first part of a claim you pay yourself. On most policies it simply comes off what you are paid, and on the AMI wording that is true right up to the point where a benefit limit is involved.

The wording gives two worked examples of its own. Where a benefit has a five thousand dollar limit and your claim is two thousand five hundred, a seven hundred and fifty dollar excess comes off your claim and you are paid one thousand seven hundred and fifty. Where a benefit has a two thousand dollar limit and your claim is two thousand five hundred, the excess comes off the limit instead, and you are paid one thousand two hundred and fifty.

Read the second one again. Where the claim is bigger than the benefit limit, the excess is deducted from the limit rather than from the claim, so the benefit never pays its full stated figure. Any capped benefit in the table above is worth less than its number by the amount of your excess.

There is one piece of good news in the same section. Where several policies you hold with AMI at the same address are involved in one claim, only the highest single excess is deducted rather than one per policy.

Your cover shrinks after a claim until the work is done

This clause is unusual enough to be worth its own section, and it is not obvious from a summary or a comparison table.

When AMI pays a claim for damage to the house or to a special feature, the relevant sum insured and the total sum insured are both reduced by the amount needed to repair that loss. The reduction applies from the start of the period of insurance, not from the date of the claim.

The wording works an example. A retaining wall claim costing sixty thousand dollars against a special feature sum insured of one hundred thousand leaves forty thousand on that wall, and reduces a total sum insured of seven hundred thousand to six hundred and forty thousand.

The cover comes back when the repair is done. Until then, a second event during the same year is working against a smaller ceiling. On a property that has already had one claim and is waiting on a builder, that is a real exposure, and it is a good reason to keep the claim moving.

Slow leaks, and the three thousand dollar limit

House insurance covers sudden accidental damage, not the slow kind. A pipe weeping behind a wall for two years is the most common way a New Zealand house is damaged without anyone noticing, and every insurer writes a narrow exception for it.

AMI covers accidental hidden gradual damage that both first happens and is discovered while the house is insured with AMI. The most it pays in a period of insurance is three thousand dollars.

Two details change how that reads. The cost to repair the cause is not covered, so the pipe or the failed seal is yours to fix. But other parts of the house that are not themselves damaged, and have to be opened up to find or reach the cause, are covered, provided AMI approves the work first.

Three thousand dollars does not go far into a wet wall, and the approval step is a condition rather than a formality. The practical reading is that this benefit helps with a small, early find, and does not rescue a house where the leak has been running for years.

Holiday homes and houses left empty

An empty house is a different risk, because nobody notices a leak, a break-in or a small fire. The AMI wording restricts cover once a house has been unoccupied, and it can change the terms of the policy at that point.

There is a way to keep full cover on a house that is regularly empty, and it is a list of conditions rather than a single tick box. Where AMI has recorded the house as a holiday home, the restriction does not bite provided all of the following are true. The house and grounds are inspected inside and out at least every sixty days by you or someone you nominate. The house, grounds and contents are adequately maintained. Mail is cleared regularly. The water supply is turned off. All doors are locked and all windows are secured.

Turning the water supply off is the one people forget, and it is the one most likely to matter. A burst pipe in an empty house is a large claim, and the condition is written to prevent exactly that.

The restriction ends as soon as you or someone you authorise is living in the house again.

The AMI and State wordings are the same document

AMI Home Plus and State Home Comprehensive are both IAG products, and reading them side by side shows how close they are. Setting the brand and product names aside, the two documents measure 99.89% identical.

That is not a family resemblance. It is the same wording, with AMI written where State appears and Home Plus written where Home Comprehensive appears. The benefits are the same benefits, the limits are the same limits, and the exclusions are the same exclusions.

The practical consequence is worth being blunt about. If you get a quote from AMI and a quote from State and treat that as comparing two policies, you are comparing one policy at two prices. The cover is not the variable. Price, service and how each brand handles a claim are.

It also means a comparison that puts both brands in a table is padding the table. Two of the columns carry the same document, and a reader who does not know that will read the agreement between them as confirmation.

Nothing here says either brand is worse for it. Shared wordings across brands owned by one insurer are ordinary, and it is cheaper to maintain one document than two. The problem is only that two brand names suggest a choice that, in cover terms, is not there.

What costs extra

Four benefits in the Home Plus wording are optional, which means they apply only if your policy schedule shows you bought them.

Additional costs for heritage homes covers the extra expense of rebuilding a house with heritage features to the standard required. Excess-free glass and bathroom fixtures removes the excess on those claims. Lifestyle block fencing extends fencing cover on a larger property. Matching floor coverings pays to replace undamaged floor covering so that a repaired room matches.

That last one is worth understanding, because the gap it fills is the single most common surprise in a house claim. Without it, an insurer pays to replace what was damaged, and not to replace the undamaged half of the same floor so that the two halves match.

What to check before you buy

None of these has a right answer that applies to every house. They are the points where the AMI wording gives a different result depending on something only you know.

Worth having in front of you:

  • Which basis of settlement your schedule shows, and if it is Replacement, whether the floor area printed on it is right.
  • Whether your retaining walls, pool or crossings are worth more than the caps inside the home sum insured, and whether they are listed as special features.
  • Where your sum insured came from and when it was last worked out.
  • If the house is ever empty for long, whether you can meet every one of the holiday home conditions, including turning the water off.
  • Whether you also hold a State quote, and whether you realise it is the same wording.
  • Whether matching floor coverings is worth buying for the rooms you actually have.

Common questions

Who underwrites AMI house insurance?
IAG New Zealand. IAG also owns State and NZI, and underwrites house policies sold under several bank brands, so an AMI claim and a State claim are paid by the same company.
Is AMI Home Plus the same as State Home Comprehensive?
The wordings are, to the extent that matters. Setting brand and product names aside, the two documents measure 99.89% identical. The benefits, limits and exclusions match. What differs between the brands is price, service and claims handling, not the cover.
What does the Replacement basis of settlement actually change?
Where the loss comes from fire or explosion that a natural hazard did not cause, and you repair or rebuild, the limit of your home sum insured does not apply. The cap is the replacement cost up to the floor area shown on your schedule instead. For every other cause, including any natural hazard, the sum insured still applies.
Are retaining walls covered by AMI?
Up to fifty thousand dollars for all retaining walls together, and that figure sits inside your home sum insured rather than on top of it. A wall worth more than that has to be listed on your policy schedule as a special feature with its own sum insured.
How much does AMI pay for temporary accommodation?
Up to thirty thousand dollars for each event, for each residential dwelling on the schedule, where the house is your main residence. It also pays where a government or local authority orders you to leave because damage is coming, even before the damage happens.

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 insurer’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 TΕ« 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.
