How to read your first house insurance policy in New Zealand

When you buy your first home, your house insurance policy can be confusing. The key thing to understand is that the policy wording explains what your insurer will pay for, what it won't pay for, and what you must do to stay covered.

Don't just look at the premium (the price you pay). Two policies can cost similar amounts but protect you differently.

Here are the main things I'd check before accepting your policy or relying on it to protect your new home.

1. The most important things to check

1. Is the house insured for enough?

Check the sum insured — the maximum amount available to rebuild your home under the policy.

• Does it reflect the cost of rebuilding, not the property's market value?
• Does it include demolition, removing debris, professional fees and applicable building costs?
• Is it enough for your home's size, construction, slope and access?

A house worth $800,000 might cost more or less than that to rebuild. Land value is not the same as rebuild cost.

2. What damage is actually covered?

Look for the section called What we cover, Insured events or similar.

Check how the policy treats:

• Fire, storms, flooding and accidental damage.
• Earthquakes and other natural hazards.
• Landslips, subsidence and retaining walls.
• Water leaks, burst pipes and gradual water damage.

Important: Sudden damage may be covered while damage that develops slowly is excluded. Flooding, groundwater, landslips and retaining walls can have specific limitations.

3. What are the excesses?

An excess is the amount you pay towards a claim.

• Check the standard excess.
• Check whether earthquakes, storms, water damage or other events have separate excesses.
• Find out whether multiple excesses can apply to one incident.

For example, with a $1,500 excess on a covered $10,000 claim, you would generally pay $1,500 and the insurer would pay the remaining $8,500, subject to the policy terms and limits.

4. What is excluded?

Find the Exclusions section. This is one of the most important parts of the wording.

Common areas to investigate include:

• Wear and tear, rot, mould and gradual deterioration.
• Existing damage or known defects.
• Faulty construction, poor workmanship or non-compliant building work.
• Unconsented alterations, where relevant.
• Damage caused by a lack of maintenance.

An exclusion does not necessarily mean every related claim is rejected. Read the exact wording and any exceptions.

5. What counts as part of the house?

Check whether cover includes:

• Garages, sheds, fences, driveways and retaining walls.
• Decks, patios, paths and swimming pools.
• Solar panels, heat pumps and other permanently installed equipment.
• Underground pipes, drains and service connections.

Some items may be covered only up to a limit, or not at all. Don't assume everything on your property is automatically included.

6. Where would you live if the house became uninhabitable?

Look for temporary accommodation, alternative accommodation or additional living expenses.

Check:

• The maximum dollar amount.
• How long the insurer will pay.
• Whether cover applies only when the home is damaged by an insured event.
• Whether extra costs such as moving or storage are included.

Rebuilding can take a long time, so this benefit can matter enormously.

2. New Zealand-specific things you shouldn't overlook

These are particularly important when buying your first home in NZ.

Natural disaster cover: understand NHCover

New Zealand has a government-backed natural hazards insurance scheme called Natural Hazards Commission Toka Tū Ake (NHC). If your private house insurance includes fire cover, you generally receive NHCover automatically.

However, NHCover is not a guarantee that your whole house and section will be fully repaired after a disaster.

• Your house: NHCover generally provides the first layer of building cover, up to $300,000 plus GST per dwelling for applicable claims. Your private insurer's policy determines the cover above that limit.
• Your land: Cover is limited to specified areas under and around the home, and certain retaining walls, bridges and culverts.
• Your private policy: Check how it responds to earthquakes, landslides, floods and storms, including any excesses and exclusions.

Read the official NHC guide to natural hazards cover. About natural hazards cover :: Natural Hazards Commission Toka Tū AkeCover for storm, flood, and landslide damage :: Natural Hazards Commission Toka Tū Ake

Check whether your particular property has special risks

Consider whether the house has:

• A steep section, retaining walls or a history of slips.
• A flood risk or a nearby stream.
• A concrete tile, long-run metal or older roof that may have specific conditions.
• A monolithic plaster exterior, an older timber house or known weathertightness issues.
• A shared driveway, private access bridge or unusual outbuildings.

These features do not automatically make a house uninsurable. But they can affect the availability, cost or conditions of cover. Ask the insurer about the actual property rather than assuming a standard policy covers every risk.

The NHC also recommends checking natural hazard risks and understanding the property's insurance position when buying a home.

3. The other clauses worth reading carefully

Policy section	What to look for in plain English
Replacement or rebuild cover	Will the insurer rebuild the house, pay a settlement, or offer different options? What conditions and limits apply?
Liability cover	Are you covered if you accidentally cause injury or property damage to someone else? What is the limit?
Temporary accommodation	Is there a dollar cap, time limit or approval requirement?
Hidden gradual damage	Is there limited cover for hidden water leaks? What must you prove, and what are the limits?
Unoccupied home	How long can the home be empty before you need to notify the insurer or meet extra conditions?
Renovations and building work	Do you need approval before renovating, extending or undertaking structural repairs?
Claim conditions	How quickly must you report damage? Must you get approval before arranging repairs?
Policy cancellation and renewal	Can the premium, excess or terms change at renewal, and how will you be notified?

Also check the policy schedule — the document listing your particular cover, insured address, sum insured, excesses and any special conditions. It can be just as important as the general policy wording.

I understand how earthquakes, flooding and landslides are covered.

I know whether my retaining walls, garage, fences, driveway and other structures are covered.

I understand the temporary accommodation limit.

I have disclosed relevant property risks and known issues honestly.

I know what to do before making a claim or arranging urgent repairs.

My lender's insurance requirements are met, if I have a mortgage.

I have checked any special conditions attached to my policy.

5. Questions to ask your insurer

If anything in the wording is unclear, ask for an answer in writing. These are good questions to start with:

• “Is my sum insured enough to rebuild this particular house, including demolition and professional fees?”
• “What would happen if an earthquake or landslide damaged both the house and the land?”
• “What damage from a leaking shower, roof or pipe would be excluded?”
• “Are any parts of my property excluded or subject to special limits?”
• “What are the circumstances in which you could decline a claim?”
• “Are there any conditions I must meet before the cover starts?”

Don't rely on a verbal assurance if the written wording appears to say something different. Ask the insurer to explain the relevant clause and confirm any agreed change in writing.

My recommendation

If you do only three things, check the rebuild sum insured, the exclusions and the natural disaster cover first. Those are the areas where an apparently good policy can leave you with a significant unexpected bill.
