Understand sum insured in New Zealand contents insurance. Learn how to calculate it correctly and avoid being underinsured for your belongings.
Understanding Sum Insured
Sum insured is the maximum amount your insurance company will pay if you need to make a claim. It's not the amount you pay for insurance—it's the limit of their liability.
Choosing the right sum insured is one of the most important decisions when buying contents insurance in New Zealand.
Calculating Your Sum Insured
The best way to determine your sum insured is to conduct a detailed home inventory. Walk through each room and list everything:
- Living room: sofa, TV, coffee table, rugs, ornaments
- Bedroom: bed, wardrobe, clothes, jewelry, electronics
- Kitchen: appliances, cookware, glassware, utensils
- Bathroom: mirrors, storage units, toiletries
- Garage/shed: tools, sports equipment, seasonal items
Estimate replacement costs for each item (what it would cost to replace at today's prices), then total the figure.
The Danger of Underinsurance
Underinsurance happens when your sum insured is less than the actual value of your belongings. If you claim and your insurer discovers you were underinsured, they can reduce your payout proportionally.
For example: If your contents are worth $50,000 but you only insured for $40,000, and you have a $10,000 claim, you might only receive $8,000.
Building in a Safety Margin
It's wise to add 10-15% to your calculated total to account for items you might have forgotten and future purchases. Prices also increase over time, so regular reviews ensure you stay properly covered.
Annual Reviews
Review your sum insured yearly, especially after major purchases like furniture or electronics. Many Kiwis find they've accumulated significant value over time without adjusting their coverage.
Get It Right
Proper sum insured means proper protection. Take time to calculate it correctly, and you'll have genuine peace of mind.
