What coverage and timing risks should I check before switching house insurance providers?
Switching house insurance providers in New Zealand is mainly about avoiding gaps in cover, unexpected exclusions, lower-than-expected claim payouts, and timing problems between policies. The cheapest premium isn't necessarily the best deal if the new policy covers less or applies different conditions.
Here’s a practical checklist to work through before cancelling your current policy.
1. Coverage risks to check
Sum insured and rebuild costs
Check that the new sum insured would cover rebuilding your home, including demolition, debris removal, professional fees, consent costs and current construction prices. Don't assume your property's market value is the right figure; land value and rebuild cost are different.
- Check whether the policy has a fixed sum insured or any additional rebuild-cost protection.
- Review special features such as retaining walls, decks, garages and outbuildings.
Natural hazards and disaster cover
Compare cover for earthquakes, landslides, flooding, storms, coastal erosion and other natural hazards. Check both the insurer's policy wording and the role of the Natural Hazards Commission Toka Tū Ake (NHC).
- Understand the excesses for earthquakes and other events, which may differ substantially.
- Check exclusions for gradual damage, land movement, sea-level-related risks and previously damaged property.
- Confirm whether retaining walls, driveways, paths and other land improvements are covered, and to what extent.
Water damage, leaks and gradual damage
Pay particular attention to hidden leaks, leaking pipes, rot, mould, faulty workmanship and water entering through roofs or foundations.
- Compare cover for sudden and accidental damage with any limited cover for gradual damage.
- Check how long a leak can have been occurring before cover is restricted, and what the maximum payout is.
- Ask how pre-existing damage or a known maintenance issue would be treated.
Special property features and exclusions
Check that the new insurer knows about any features that could affect eligibility or premiums, including older construction, unusual materials, unconsented alterations, a long-term vacant property, home-based business use or a rented portion of the house.
Compare cover for matching materials, temporary accommodation, demolition, code upgrades, alternative accommodation limits and emergency repairs.
Excesses, limits and settlement rules
A lower premium may come with a higher excess or tighter sub-limits. Compare the excess for each major event, not just the standard excess.
Also check whether the insurer pays to repair or rebuild, how partial damage is settled, and whether special limits apply to fences, sheds, retaining walls and other structures.
2. Timing risks when you change insurers
The most important rule is to get the new cover confirmed before cancelling the old policy.
- A gap between policies
Confirm the new policy's exact start date and time in writing. Don't rely on an online quote, an application submission or a verbal indication that you are eligible.
- Damage just before or during the switch
If a storm, leak, earthquake or other damaging event occurs before the new policy starts, the old policy may be the relevant policy, even if you discover the damage later. Notify the insurer promptly and keep photos, dates and repair records.
- Existing damage or an unresolved claim
If you have a current claim, known damage, a leaking roof or unrepaired earthquake damage, ask both insurers how the situation will be handled before switching. The new insurer generally won't cover damage that already occurred before its cover began.
- Acceptance conditions and waiting periods
Check whether the new insurer has accepted the risk unconditionally or requires inspections, repairs, further information or other conditions. Ask whether any waiting period or special exclusion applies to your particular cover.
- Mortgage and payment administration
If your home has a mortgage, check that the new policy meets your lender's insurance requirements and that any interested-party details are correct. Confirm the old policy's cancellation date, refund arrangements and any outstanding premium.
One important New Zealand-specific point: if your home has fire insurance, it will generally have access to government natural hazards cover through the Natural Hazards Commission Toka Tū Ake (NHC). However, that is not comprehensive cover for every building, land feature or disaster-related expense. The applicable legislation also depends on when the damage first occurred.

3. New Zealand-specific checks
Before making the change, pay particular attention to these issues:
- NHC and private cover: Check how the new policy coordinates with NHCover and what it covers above the government building cap. The NHC's official guide to natural hazards cover explains the distinction.
- Land and retaining walls: Don't assume the home sum insured covers your entire section. Government land cover is limited, and private policies may have separate limits for retaining walls, driveways and landscaping.

- Property risk information: Disclose known damage, previous losses, relevant hazard information and any material property details accurately. Incorrect or incomplete answers can jeopardise a claim or, in some circumstances, the policy itself. See Consumer Protection NZ's insurance guidance. Insurance
- Current or past natural-hazard damage: If the property has had a major claim or repairs remain incomplete, check whether any title notices or restrictions affect cover. Ask the insurer and, where relevant, the NHC to clarify the implications. Section notices :: Natural Hazards Commission Toka Tū Ake
4. A final comparison checklist
Use this before you accept the new policy.

My recommendation: Don't cancel the existing policy until the replacement cover is confirmed, the important exclusions have been compared, and any existing damage or claims have been addressed. A short period of overlap may be preferable to a gap, but confirm the cost and terms first.
