Every question, every answer, every source

The best house insurance policy isn’t necessarily the cheapest one — it’s the one that would leave you in the best position to repair or rebuild your home after a major loss, without unexpected gaps in cover.

In New Zealand, two policies can have similar premiums but differ significantly in what they pay for, how they calculate rebuild costs, and which events or expenses they exclude.

My recommendation is to compare the policy wording, not just the quote summaries. Here’s how to do that.

1. Compare the cover that matters most

Use this checklist to compare your two quotes side by side.

What to compare	What makes cover better?
Rebuild cover	A suitable sum insured or rebuild arrangement that accounts for demolition, professional fees, materials and current building costs.
Natural hazards	Clear cover for events such as earthquakes, landslips, floods and storms, subject to policy terms and statutory arrangements.
Temporary accommodation	Enough cover, for long enough, if your home becomes unliveable. Check dollar limits and time limits.
Hidden costs after a claim	Cover for debris removal, demolition, architects, engineers, council requirements and building-code upgrades where applicable.
Excesses	Lower or more manageable excesses, especially for different types of claims such as earthquakes or natural hazards.
Accidental damage	Whether sudden accidental damage is covered, and which exclusions or limits apply.
Water damage	Whether gradual leaks, hidden water damage, burst pipes and resulting damage are treated differently.
Retaining walls, driveways and outbuildings	Appropriate limits for garages, fences, sheds, paths, swimming pools and retaining walls.
Special features	Specific cover for solar panels, heat pumps, decks, renovations or other expensive features, where relevant.
Claims settlement	Clear rules on whether the insurer repairs, rebuilds or pays cash, and how underinsurance is handled.

A policy with a higher headline limit isn’t automatically better. The definition of what is insured and the exclusions can matter just as much.

2. Check the rebuild amount carefully

This is one of the most important comparisons in New Zealand.

Most policies use a sum insured — the maximum amount available under the policy, subject to its terms. Don't confuse this with the market value of your property, which includes the land.

Your rebuild estimate should account for:

• The cost of rebuilding the house to a similar size and standard.
• Demolition and debris removal.
• Architects, engineers and other professional fees.
• Council consents and current building-code requirements.
• Driveways, retaining walls and other structures, where covered.
• GST and potential increases in building costs.

These costs can add up significantly after a major loss. Check whether either policy provides additional cover above the sum insured and whether that extra cover applies to natural hazards as well as other events.

3. Understand New Zealand's natural hazard cover

New Zealand's Natural Hazards Commission Toka Tū Ake (NHC) provides statutory natural hazard cover for eligible insured homes, with private insurance generally providing cover above the applicable statutory limit.

For eligible claims under the current scheme, the building cover cap is generally $300,000 plus GST per dwelling per event, subject to the rules and limits that apply. Your private policy's terms and sum insured remain important.

For both quotes, check:

• How the insurer covers damage above the NHC limit.
• What happens if the damage is caused by flooding, landslip or another event with different coverage rules.
• Whether there are special excesses for earthquakes or other natural hazards.
• What cover applies to retaining walls and land-related damage.

Don't assume that two policies offer identical protection simply because both mention earthquake cover.

4. Compare the excesses, not just the premiums

Your excess is what you pay towards an accepted claim. A cheaper policy might have a substantially higher excess for a particular type of damage.

For example, imagine these hypothetical quotes:

	Quote A	Quote B
Annual premium	$2,000	$1,800
Standard excess	$500	$1,500
Temporary accommodation	$50,000	$20,000
Hidden gradual water damage	$5,000 limit	Not covered

Quote B saves $200 a year, but you could pay an extra $1,000 on a standard claim and have much less protection for accommodation and hidden water damage.

The better option depends on your property and what you could afford to pay yourself. Also check whether excesses are different for different claim types, rather than assuming the standard excess applies to everything.

5. Read the exclusions and special conditions

This is where seemingly similar policies can differ most.

Look for the following terms in each insurer's policy wording:

• Gradual damage: Is hidden damage from a slow leak covered? What about rot, mould or deterioration?
• Maintenance: What happens if damage results from poor maintenance or an existing defect?
• Flooding and water: Are surface water, groundwater, stormwater and water entering through the building treated differently?
• Unoccupied homes: How long can the house be empty before restrictions apply?
• Renovations: Must you notify the insurer before substantial building work?
• Settlement: Can the insurer choose to repair, rebuild or pay a cash settlement? Under what conditions?

A key distinction is between damage caused by a sudden event and damage that develops over time. The latter is often restricted or excluded, although some policies provide limited cover for particular types of hidden gradual damage.

For the most reliable comparison, read the actual wording that applies to each quote, including any endorsements or optional extras.

6. Score your two quotes side by side

Here's a simple comparison worksheet you can use. Give each policy a score from 1 to 5 for each category, based on how well it meets your needs.

For independent New Zealand guidance, Consumer NZ has a house insurance buying guide and the Insurance Council of New Zealand explains house insurance and sums insured.

Want me to compare your actual quotes?

The most useful next step is to share the two quotes, or upload their summaries and policy wording documents. You can remove your name, address, policy numbers and other personal details first.

I'll compare them on:

• Which policy provides stronger protection for a major loss.
• Differences in exclusions, excesses and additional benefits.
• Whether either rebuild limit looks potentially inadequate.
• Any important gaps or trade-offs that aren't obvious from the premiums.
• Which one offers the better overall value for your home.

You don't need to interpret all the insurance jargon yourself — I can work through the differences with you.
