House & Contents Insurance NZ 2026

What House & Contents Insurance Actually Is

Two separate covers, usually sold together on one policy and one bill.

"House and contents insurance" is not a third product. It is house insurance and contents insurance bought together. House cover protects the building: the structure, fixtures, fittings, and usually outbuildings like a garage or shed. Contents cover protects what you would take with you if you moved: furniture, appliances, clothing, and electronics.

Buying them together changes three practical things. You generally get a multi-policy discount on both premiums. Several insurers charge you only one excess when a single event damages both the building and its contents. And you deal with one insurer, one renewal date, and one claim when something goes wrong.

What bundling does not do is merge your cover into one pot of money. You still set two separate sums insured: a rebuild figure for the building and a replacement figure for the contents. Getting either one wrong has the same consequences as it would on a standalone policy.

One thing to know before you start: the Natural Hazards Commission Toka Tū Ake (NHC, formerly EQC) covers the building portion only, up to $300,000 + GST. It has not covered contents since 1 July 2019, so your contents are protected entirely by the private policy. See our guide to NHC cover.

Bundling is a pricing and admin decision, not a cover decision. The cover you get is the same as buying the two policies separately from the same insurer. What changes is the price, the excess treatment, and how many phone calls you make at claim time.

One Event, One Excess: The Benefit Most People Miss

If a flood damages your floors and ruins your furniture, that is one event hitting two policies. Several NZ insurers charge a single excess in that situation rather than two.

AA Insurance

AA Insurance lists "One event, one excess" as a standard benefit of being an AA Insurance customer, applying across eligible policies.

Tower

Tower's wording is "pay only the highest excess if one event means claims on multiple eligible policies". You pay the larger of the two excesses, not both.

Vero

Vero applies one excess if you claim on more than one of your Vero car, house and contents policies at the same time and location. Available on both Maxi and Flexi cover.

Initio

Initio states plainly that if both your house and contents are damaged in the same event, such as a flood, you will only pay one excess.

What it is worth

With typical excesses of $400 to $1,000 on each policy, this benefit is worth several hundred dollars on a single claim. It only applies when both policies are with the same insurer, which is a genuine argument for bundling rather than splitting across two providers.

Check before you assume

Not every insurer offers this, and the conditions differ. Some require the same event, others the same time and location. Confirm the exact wording with your insurer rather than assuming a single excess will apply.

Multi-Policy Discounts Compared

What each insurer publishes about bundling discounts. Most describe them as "up to" a maximum, so the figure you are quoted depends on which policies you hold and the insurer's minimum premium rules.

Provider	Underwriter	Published discount	One event, one excess	How to buy
Tower	Tower Ltd	Up to 10% with two policies, up to 20% with three or more	✓ Pay the highest excess only	Online
AA Insurance	AA Insurance Ltd	AA Member multi-policy discount	✓ Standard benefit	Online
Vero	Vero Insurance NZ Ltd	Check with broker	✓ Same time and location	Broker
Initio	IAG New Zealand Ltd	Check at quote	✓ Same event	Online
AMI	IAG New Zealand Ltd	Multi-policy discount available	Check with AMI	Online

Trade Me Insurance	Tower Ltd	Check at quote	Check with insurer	Online

Disclaimer: Discount figures are those published by each insurer and were checked on 22 July 2026. Tower's tiers are taken from its published multi-policy discount terms. Discounts are applied to the insurer's premium before taxes and levies, are expressed as a maximum, and can be affected by minimum premium rules. They are not a quote. Confirm what you will actually be charged directly with the insurer. Spotted an error?

Setting Two Sums Insured

The single biggest mistake on a bundled policy is treating one number as if it covered both.

Building: your rebuild cost

This is not your property's market value and not its rating valuation. It is what it would cost to demolish and rebuild the same house on the same site, including demolition, professional fees, council consents, and compliance with current building codes. AMI and State both point customers at the Cotality Sum Sure calculator; Vero uses a Cordell calculator. See our sum insured guide.

Contents: your replacement cost

This is what it would cost to replace everything you own at today's prices, not what you originally paid. Most NZ households significantly underestimate it. A typical three-bedroom home holds $80,000 to $150,000 of contents. Do a room-by-room inventory rather than guessing. See how much contents cover you need.

High-value items need listing

Items above a per-item limit, typically $2,000 to $5,000, have to be specified individually. Jewellery, art, instruments, cameras and high-end electronics are the usual culprits. Tower, for example, caps unspecified jewellery at $30,000 in total. Anything above the per-item limit that you have not declared may not be fully covered.

Underinsurance hits both sides

Because the two sums insured are independent, you can be correctly insured on the building and badly underinsured on the contents at the same time. Review both figures at every renewal, especially after renovations, a large purchase, or a period of high building cost inflation.

What to check before you buy

Recalculate your rebuild figure at least every two years
Redo your contents inventory after any major purchase
List high-value items individually rather than assuming they are covered
Check whether your excess applies once or twice when one event hits both
Confirm the multi-policy discount actually appears on your renewal notice

How we rate: Ratings are Compare.org.nz editorial scores, assessed separately for each type of cover, so the same brand can score differently for house, landlord or contents insurance. Scores reflect published policy benefits, cover breadth, price positioning and how easy the insurer is to buy from and claim with. They are our opinion, not advice, not a guarantee of service, and not a measure of financial strength. Benefit limits were checked against each insurer's own product pages on 22 July 2026.

When Splitting Across Two Insurers Makes Sense

Bundling is usually cheaper, but not always the right answer.

Unusual building risk

If your home has a characteristic that one insurer prices harshly, such as a coastal or flood-zone location, an older build, or a difficult land classification, the building premium can dominate the bundle. A specialist on the building side may beat the bundled discount.

High-value contents

Large jewellery, art or instrument collections push you past standard unspecified limits. An insurer that handles specified items well may be worth splitting for, even though you lose the multi-policy discount and the single-excess benefit.

MAS eligibility

MAS only accepts medical, dental and veterinary professionals. If one person in a household qualifies and the other does not, how the policies are structured affects what you can bundle.

Do the arithmetic

Compare the bundled total against the two cheapest standalone premiums, then subtract the value of one avoided excess in a claim year. A 10% discount on a $2,500 combined premium is $250. If splitting saves more than that, splitting wins on price.

House & Contents Insurance FAQs

Common questions about bundling building and contents cover in New Zealand.

Is house and contents insurance cheaper than buying them separately?

Usually, yes. Insurers apply a multi-policy discount when you hold more than one policy with them. Tower publishes its tiers as up to 10% off each eligible policy with two policies and up to 20% with three or more. On top of the discount, several insurers charge only one excess when a single event damages both your building and your contents, which can be worth several hundred dollars at claim time.

Do I set one sum insured or two?

Two. You set a rebuild figure for the building and a separate replacement figure for the contents. They are not interchangeable and one does not top up the other. This is the most common mistake on bundled policies, because people assume a single combined figure covers everything.

If a flood damages my house and my furniture, do I pay two excesses?

It depends on the insurer. AA Insurance, Tower, Vero and Initio all publish a single-excess benefit for one event affecting multiple policies, though the conditions differ. Tower charges the higher of the two excesses. Vero requires the claims to be at the same time and location. Confirm the exact wording with your insurer rather than assuming.

Does NHC cover my contents in a bundled policy?

No. The Natural Hazards Commission Toka Tū Ake covers residential buildings and some land, up to $300,000 + GST, with a $500 excess on claims from 1 July 2024. Contents cover was removed on 1 July 2019, so your contents are protected entirely by the private portion of your policy, including for natural disasters.

Can I bundle if I rent?

Not in the usual sense, because the building is your landlord's responsibility. What you need is renters insurance, which is contents cover for tenants. You can still bundle contents with other policies such as car insurance to earn a multi-policy discount.

Is house and contents insurance compulsory in New Zealand?

No, it is not legally compulsory. However, if you have a mortgage, your lender will almost certainly require building insurance as a condition of the loan. Contents cover is optional in every case, though it is what protects the belongings a mortgage does not care about.

Do both policies have to renew on the same date?

Not necessarily, but insurers usually align them when you bundle, which is part of the administrative benefit. Aligned renewal dates make it easier to review both sums insured at the same time, which is worth doing at least annually.
