How much life insurance do I need in NZ?
The honest answer: enough to discharge your debts and replace your income through your family's dependent years. The right number for you depends on your specific debts, income, and dependents — not a national average. This page walks through the methodology; plug your own numbers in.
The four-component method
Most NZ advisers size life cover as the sum of four components:
- Mortgage discharge. Your outstanding mortgage balance — what's left to pay if you died today. The number is on your latest mortgage statement.
- Income replacement. Net household income × years of dependency. A common rule of thumb is 10-15 years for households with school-age kids. Adjust upward if your kids are very young; downward if your surviving partner has strong independent earning capacity.
- Outstanding personal debt. Credit cards, personal loans, BNPL. Student loans are wiped on death in NZ but still useful to know.
- Funeral + transition costs. Your family needs cash immediately — before any life payout lands. A buffer for funeral plus a few months of basic living expenses is sensible.
What to NOT count
- Existing life cover. If you already have group cover via employer or KiwiSaver-attached policy, that figure comes off the top.
- Spousal income. If your partner earns enough independently to cover living costs, you can size cover smaller.
- Substantial assets. Investment accounts, KiwiSaver balance, second property — these soften the household's reliance on life cover.
Worksheet — plug your own numbers
We don't publish worked examples with specific figures — every household's numbers are different and stale ranges mislead. Use a spreadsheet or our calculator:
- Mortgage outstanding
- Other debts (credit cards, BNPL, personal loans)
- Annual net household income × years of dependency
- Funeral + transition buffer
- Less existing cover
- = Sum-insured target
How premium scales with sum-insured
Higher sum-insured = higher premium, but not always linearly — many NZ insurers band-price in tiers, and the premium-per-thousand-of-cover often decreases as sum-insured grows. Always quote at multiple sum-insured levels to see the actual shape.
Stepped vs level — the bigger lever
Choice of premium structure has more impact on lifetime cost than minor sum-insured differences. Stepped is cheaper at signup but compounds; level is flatter. See our topic comparison for verbatim wording across NZ insurers.
