We're looking at a cheaper house policy that seems to cover only certain types of damage. How do we know what we'd be giving up?
The key is to compare what the cheaper policy would actually pay for when something goes wrong, rather than just comparing the premiums.
In New Zealand, a cheaper house insurance policy may cover only specified types of damage, such as fire, storm or flood. Another policy may offer broader cover for sudden, accidental damage, subject to exclusions and conditions. The difference can matter a lot if your home is damaged in a way you hadn't anticipated.
I'd look at three things: what is no longer covered, how much you'd have to pay yourself, and whether the policy leaves you exposed to a large repair or rebuilding bill.
1. What you might be giving up
Consumer NZ explains that basic policies may cover specified major events, while comprehensive policies can also cover accidental damage caused by you or your family. Limits for extra benefits can differ, too. How to get the best house and contents insurance
Here is a practical checklist to use when comparing your two policies.
| Type of damage or cost | What to check in the cheaper policy |
|---|---|
| Fire and explosion | Are these covered, and are there any special conditions? |
| Storm, flood and water damage | Which events are included? Is water entering through a roof or window covered? |
| Accidental damage | If you accidentally damage a wall, floor or fixed fitting, will it pay? |
| Leaking pipes | Is resulting damage covered? What about hidden, gradual leaks? |
| Wear, rot and mould | Usually excluded, but check how the policy treats resulting damage from another event. |
| Retaining walls, fences and driveways | Are they included, and what are the dollar limits? |
| Temporary accommodation | How much will the insurer pay if you cannot live at home? |
| Demolition and rebuilding | Are demolition, debris removal, professional fees and consent costs covered within the rebuild limit? |
These are common areas to investigate, not a list of benefits that every comprehensive policy includes. See the Insurance Council of New Zealand guide to common insurance exclusions. What Home, Contents & Car Insurance Don't Cover (NZ)
2. Pay special attention to these three risks
Water damage
Ask what happens if a pipe bursts, a shower leaks, or rain enters through a damaged roof. The cause of the damage and whether it developed gradually can determine whether a claim is accepted.
Everyday accidents
If someone puts a hole in a wall, damages a fixed fitting or accidentally breaks something structural, check whether the policy covers the resulting damage. A specified-events policy may leave you paying for some accidents yourself.
A major loss
Check the maximum payout and whether it would cover rebuilding the house, demolition, professional fees and other necessary costs. A policy with a lower premium is not a bargain if its payout limit is inadequate.

3. Compare the actual policy documents, not just the summaries
Get the full policy wording and the policy schedule for both options. Then compare:
- Insured events: Is the policy limited to named events, or does it cover accidental damage more broadly?
- Exclusions: Which causes of damage are specifically excluded?
- Excesses: How much must you pay per claim, including any separate excesses for particular events?
- Limits and sublimits: Are there caps on temporary accommodation, retaining walls or other property features?
- Rebuild cover: Is it replacement cover or a capped amount, and is the sum insured realistic?
The Consumer Protection insurance guide explains why exclusions, policy conditions and disclosure obligations matter. Insurance'Sum Insured' cover for household insurance - what are the risks?
4. Is the saving worth the risk?
For example, suppose the cheaper policy saves you NZ$400 a year. Over five years, that is NZ$2,000 in premiums saved, before allowing for premium changes.
That saving may be worthwhile if the lost benefits are minor and you could comfortably afford the repairs they leave uncovered. It may not be worthwhile if you could be left paying tens of thousands of dollars for a major repair.
I can help you compare your two options
The most useful next step is to look at the actual policies side by side.
Can you tell me the names of the two insurers and the policy types you're comparing? If you have the policy summaries or wording, you can also paste them here or upload the documents. I'll identify the specific cover you'd lose, the important exclusions and limits, and which differences are most financially significant for your home.
