We have lots of small things but can't afford a huge contents policy. How do we avoid insuring them for too little?
If you have lots of small possessions, the trick is to insure the total value of what you own without paying to insure every item individually. In New Zealand, there are a few practical ways to reduce the risk of being underinsured without automatically buying a huge contents policy.
1. Work out what everything would cost to replace
It is easy to underestimate the value of everyday belongings because each item seems inexpensive on its own. But clothes, shoes, kitchenware, bedding, books, tools, electronics and small appliances can add up to thousands of dollars.
- Think replacement cost, not second-hand value. What would it cost to buy equivalent items new?
- Estimate by category. You don't need to list every spoon, T-shirt or towel individually.
- Include the things you might forget. Items stored in cupboards, the garage, the shed and under the bed all count.
- Don't forget the little extras. Chargers, cables, accessories, cookware and cleaning equipment can be surprisingly costly to replace.
2. Use a contents calculator rather than itemising everything
A free online calculator can estimate the cost of replacing the contents of your home based on the rooms and types of possessions you have.
Try the NZI contents sum insured calculator or the ASB contents calculator. Use the result as a starting point, then adjust it for things you own that the estimate might miss. Contents CalculatorContents insurance calculator - Find your sum insured
3. Insure the total, but check limits on individual items
In New Zealand, a contents policy generally has a sum insured covering your belongings collectively. You don't normally need to list every low-value item separately.
However, some categories have individual or combined payout limits. Jewellery, watches, bicycles, cameras and collections are common examples. If something exceeds the policy's limit, you may need to list it separately as a specified item.

4. Keep the premium affordable without guessing too low
- Compare several insurers using the same estimated replacement value.
- Ask whether a higher excess would reduce your premium enough to be worthwhile, provided you could afford that excess after a loss.
- Check whether the policy covers replacement with new equivalents or pays present-day value for certain older belongings.
- Review your sum insured at renewal and after significant purchases.
These checks help you avoid paying for unsuitable cover or discovering after a major loss that your policy won't cover enough. House & Contents Insurance: Sum Insured ExplainedUnderstanding your contents sum insured
My recommendation: Don't try to solve the premium problem by deliberately choosing a low contents value. First calculate the realistic replacement cost, then compare policies and excesses to find affordable cover.
One important question: When you say you have lots of small things, do you mean ordinary household belongings (clothes, kitchenware, books, etc.), or lots of small valuable items (such as jewellery, collectibles, tools or hobby equipment)? The best way to avoid underinsurance differs between those two situations.
