What should I compare before switching contents insurer after a renewal increase?
If your contents insurance premium has gone up at renewal, it’s worth comparing other insurers before accepting the increase. In New Zealand, the key is to compare what you would actually be covered for after a loss, not just the annual premium.
A cheaper policy can have a lower contents limit, higher excesses, more exclusions or less cover for belongings outside your home. Here’s what I’d check before switching.
1. The most important things to compare
| What to compare | What to look for |
|---|---|
| Annual premium | The full yearly cost, including fees and any discounts that expire after the first year. |
| Contents sum insured | Enough to replace everything you own at today's prices, not its second-hand value. |
| Excess | The amount you pay towards a claim. Check standard, accidental-damage and special excesses. |
| Replacement cover | Whether damaged or stolen items are replaced new-for-old, or paid out at an assessed value. |
| Accidental damage | Whether spills, breakages and other mishaps are covered, and whether this is optional. |
| Theft and burglary | Whether forced entry is required and whether theft from unlocked premises is excluded. |
| Items away from home | Cover for phones, laptops, jewellery, bicycles and other belongings taken outside your home. |
| High-value items | Per-item limits and whether jewellery, watches, art or collectibles must be individually listed. |
| Natural disasters and water damage | How the policy treats flooding, storm damage, leaks and other events, including relevant exclusions. |
| Temporary accommodation | Whether the policy helps with additional living costs if your home becomes uninhabitable following an insured event. |
2. Check why your renewal increased
Before switching, ask your current insurer for a breakdown of the increase. Your premium may have risen because of changes to the sum insured, insurer pricing, your claims history or broader risk factors.
Try these steps:
- Ask whether they can offer a better renewal price or a retention discount.
- Check whether your contents sum insured has increased and whether it still reflects the value of your belongings.
- Ask whether a higher excess would reduce the premium enough to be worthwhile.
- Check for multi-policy discounts if you also insure your car or home with them.
- Compare the final annual cost, including any fees and levies.

3. Check these New Zealand-specific details
- Natural hazards: Read the exclusions for flooding, storm damage, landslips and other events. Cover depends on the specific policy and circumstances.
- Liability cover: Check whether you're covered if you accidentally damage someone else's property, and the maximum benefit.
- If you rent: Confirm whether your belongings are covered at your rental property, in storage or while moving. Contents insurance doesn't normally insure the building itself.
- Claims service: Compare customer satisfaction, communication and how claims are assessed, not just premiums. How to get the best house and contents insuranceWhat Home, Contents & Car Insurance Don't Cover (NZ)

4. Compare the real cost of switching
Here is a simple example of why the cheapest premium isn't always the best deal.
| Current policy | Alternative policy | |
|---|---|---|
| Annual premium | $480 | $360 |
| Standard excess | $250 | $750 |
| Annual saving | — | $120 |
| Extra excess per claim | — | $500 |
In this example, you'd save $120 per year, but pay an extra $500 if you made a claim subject to that excess. If you needed to claim within the next few years, the higher excess could outweigh the premium savings.
These figures are illustrative, not market quotes.
5. Don't cancel until the replacement policy is confirmed
Once you've chosen a new insurer:
- Confirm the new policy has been accepted, including any special conditions.
- Check the start date and make sure it begins before your existing policy ends.
- Disclose relevant information accurately, including previous claims and anything the insurer asks about your circumstances.
- Save the policy wording, schedule, premium quote and confirmation of cover.
- Cancel the old policy at the appropriate time and check whether any refund or cancellation fee applies.
My recommendation
Get at least two competing quotes using the same contents sum insured, comparable excesses and equivalent cover options. Then ask your current insurer to match the best suitable quote.
To help you narrow down the comparison, one question: which insurer are you currently with, and what is your new annual premium? I can help you work out whether the increase looks worth challenging and what to compare next.
