The 5 insurance types most NZ households weigh up
Life insurance pays a lump sum to your family if you die, typically used to clear debts and replace lost income. Income protection replaces part of your income if illness or injury stops you working. Health insurance helps you skip public hospital waitlists for non-urgent treatment. House and contents insurance covers your home and belongings, and car insurance covers your vehicle and liability to others.
Not every household needs all five at once — a single renter with no dependants has a very different risk profile to a homeowner with a mortgage and young children. The right mix is personal, but understanding what each one actually does is the first step.
"Insurance isn't about covering everything — it's about covering the losses you couldn't absorb yourself."
How to prioritise when you can't afford everything
A useful way to think about it: insure the losses that would be financially catastrophic first, and the smaller, more manageable ones last. Losing your income for months, or leaving your family with a mortgage and no income earner, tends to rank above protecting the resale value of a five-year-old car.
Common mistakes: over-insuring vs under-insuring
Under-insuring — setting your house sum insured too low, or skipping income protection because "it won't happen to me" — is the more common and often more costly mistake, since it only becomes visible at the worst possible time: when you need to claim. Over-insuring (e.g. stacking multiple overlapping policies) wastes money every month but is easier to fix once spotted.
Quick check: renting or own a home?
As a renter, house insurance isn't your responsibility — that's on your landlord. Contents insurance for your own belongings, plus income protection if anyone relies on your pay, tend to matter most. Check the income protection calculator to start.
What you can do now
- Start with income and life cover. These usually protect against the biggest financial shocks — try the life insurance cover calculator and income protection calculator.
- Check your house isn't underinsured. Use the house & contents calculator to see a realistic premium range for your rebuild cost.
- Compare your car cover options. See how comprehensive vs third party changes the numbers in the car insurance cost calculator.
- See if a higher excess makes sense. The insurance excess calculator shows the trade-off between premium and out-of-pocket risk.

Generally, the cover that protects against the losses you couldn't absorb yourself — for most people that means income protection and life cover if others depend on you, since losing your income or leaving debts behind tends to be more financially catastrophic than losing a possession.
Yes — overlapping cover (e.g. life cover through both a standalone policy and a KiwiSaver or super scheme without realising it) or cover for risks you could easily self-insure against wastes money every month. It's worth reviewing your policies periodically rather than just adding new ones.
Significantly. A single renter with no dependants and no debt has a much smaller insurance need than a homeowner with a mortgage, a partner and young children — revisit your cover whenever your circumstances change (a new mortgage, a new baby, a new job).
