Why Life Insurance Premiums Increase Every Year in NZ

New Zealand life premiums rise every year mainly because most policies are stepped, so the rate per $1,000 of cover is recalculated at each birthday; on the QuoteHub Premium Index, a non-smoking man's cheapest stepped rate for $1,000,000 of life cover runs about $50 to $60 a month at 30 to about $550 to $575 at 60, indicative standard rates from insurers' published rate cards as at 8 September 2026 (see, for example, Fidelity Life's published rates). CPI indexation adds a further rise, and insurers periodically reprice their whole rate card when claims run ahead of what was priced in. A level premium locks the rate for a fixed term instead, starting higher but removing the age step. A licensed adviser can work out which force produced a specific renewal notice.

In short

A renewal letter usually blends two or three of these forces into one figure. Working out which one did it decides whether to accept the rise, decline part of it, or restructure the cover.

Why do life insurance premiums go up every year in NZ?

Most New Zealand life policies are sold stepped, so the rate per $1,000 of cover is recalculated at each anniversary against your current age. Fidelity Life explains that insurers use population, industry claims and their own data to work out the likelihood of a claim at each age, and that likelihood rises every year, so the rate does too. Three mechanisms can show up in one notice: the age step, a CPI-driven increase, and a rate-card repricing, covered below.

How much do stepped premiums rise with age? The Index at 30, 40, 50 and 60

Across four ages in the QuoteHub Premium Index, the cheapest quoted stepped premium for $1,000,000 of standard, non-smoker life cover runs as follows.

Age Female non-smoker Male non-smoker
30 $35 to $40 $50 to $60
40 $50 to $60 $70 to $80
50 $140 to $150 $170 to $180
60 $400 to $425 $550 to $575

Cheapest monthly premium at each age, rounded to a range, QuoteHub Premium Index: indicative standard rates from insurers' published rate cards as at 8 September 2026, stepped, occupation class 1, subject to underwriting (see, for example, Fidelity Life's published rates).

From 30 to 60 the cheapest male rate rises roughly ten-fold and the female rate roughly eleven-fold, on cover that has not changed. None of that is CPI or repricing; it is the pure effect of age.

What is CPI indexation and why does it add to the increase?

CPI indexation, usually on by default, lifts your sum insured each year with the Consumers Price Index, and the extra cover is charged at your current age. Stats NZ recorded annual inflation of 4.1% to June 2026, above the Reserve Bank's 1% to 3% target band, so a CPI-linked renewal can move by roughly that much on top of the age step. Fidelity Life confirms the increase is priced as ordinary extra cover at your current age, so it compounds with the stepped rate rather than replacing it. Our CPI guide covers when keeping it on is worth the cost.

Why do insurers reprice the whole rate card, not just your age band?

Age and CPI explain a gradual rise. They do not explain the sharper jumps that appear when an insurer decides its rates no longer cover its claims. Fidelity Life increased rates across life, trauma, TPD and income protection covers by 5% to 7.5% from 1 April 2025, and Partners Life applied three rises to its Private Medical Cover through 2025, including 23% for existing customers from October, citing rising claims costs. This is why the Index carries a snapshot date: rate cards are versioned documents.

Level premiums: the alternative that avoids the yearly step

A level premium locks the rate at the age you buy, for a term such as level to 65 or level to 80, removing the age step while the term runs. KiwiCover's published rate card for one insurer shows a 30-year-old male non-smoker on $500,000 of cover paying about $15 to $20 a fortnight rate-for-age against about $50 to $60 locked level to age 80: indicative standard rates, nearly three times as much to start. It is not immune to the other forces: CPI still applies if selected, insurers can still reprice the level rate, and cover reverts to rate-for-age once the term ends. Our stepped vs level guide works out when the extra cost pays off.

Can a premium jump suddenly rather than gradually?

Yes, most sharply when a level term expires and the policy converts to rate-for-age. IFSO reviewed a complaint from a policyholder whose life premium rose from about $45 to $50 a month to about $180 to $200 a month, roughly a threefold increase, the month he turned 80 and his level-to-80 policy converted to rate for age. The complaint was not upheld: IFSO found insufficient evidence the adviser had misled the couple, and that the policyholder would have paid more overall had he kept his original stepped policy. The lesson is in the schedule, not the letter: check what your cover converts to, and when.

What should you do when the renewal letter arrives?

Start by identifying which force produced the number, since the response differs for each. IFSO recommends checking your policy at every renewal and telling your insurer early if the new premium is a genuine hardship, which can unlock payment support rather than a lapse. On a CPI-driven rise, decline that year's increase and keep the sum insured. On an age-based or repriced rise, Fidelity Life's own advice is to talk to an adviser about adjusting cover rather than cancelling outright, since trimming cover to match a shrinking mortgage usually beats re-underwriting elsewhere. Our guides to reviewing cover and changing a policy safely cover the mechanics.

Frequently Asked Questions

Will my premium keep increasing every year?

On a fully stepped policy, yes, accelerating from the mid-40s, as the table above shows. Moving to a level structure is the main way to stop it, though CPI and repricing can still apply.

Is an increase bigger than the CPI figure unusual?

No. CPI only explains the sum-insured part. Fidelity Life's 5% to 7.5% rise and Partners Life's 23% rise are each larger than the 4.1% CPI figure for the year to June 2026.

Can I decline the CPI increase and keep everything else the same?

Yes, usually for that year only. Fidelity Life's Chief Commercial Officer says customers can speak with their adviser about declining the increase or adjusting cover.

Does switching insurers fix a large increase?

Not automatically. New underwriting applies, and any condition since could be loaded or excluded. A licensed adviser can compare the price against the panel first.

What if I genuinely cannot afford the new premium?

Tell your insurer before you miss a payment. IFSO's guidance is to raise hardship directly with the insurer, which will confirm what support is available, rather than letting cover lapse.
