The Cost of Waiting to Buy Life Insurance in NZ, Honestly Calculated
A New Zealand man who takes out $500,000 of stepped life cover at 25 and holds it to 65 pays about $64,181 in total, and one who waits until 45 pays about $53,950, on the price points published by Canstar New Zealand (published 3 September 2024, last updated 19 August 2026). Waiting twenty years lowers the total bill by $10,231. It also removes twenty years of protection. The usual claim that waiting costs you more in premiums is not what the published figures show.
That is worth saying clearly because the industry says the opposite constantly, and the correction matters. There is a real and serious cost to waiting. It is just not the one in the headline.
Does waiting really cost more in premiums?
No. On every published New Zealand grid we could find, the later you start, the less you pay in total, because you are buying fewer years of cover. The chart below runs Canstar's own price points from each starting age through to 65.
Chart: total premiums to age 65 for $500,000 of stepped cover, calculated by QuoteHub from the age points published by Canstar New Zealand. Published illustration only, not a quote.
| Starting age | Years of cover to 65 | Male non-smoker, total | Female non-smoker, total | Cost per year of cover, male |
|---|---|---|---|---|
| 25 | 40 | $64,181 | $48,605 | $1,605 |
| 35 | 30 | $59,500 | $45,446 | $1,983 |
| 45 | 20 | $53,950 | $40,828 | $2,698 |
| 55 | 10 | $41,361 | $30,264 | $4,136 |
QuoteHub calculation. Each year's cost is interpolated at a constant compounding rate between the five age points published by Canstar New Zealand for $500,000 of stepped cover, then summed to age 64. No allowance is made for inflation or insurer rate reviews. Published illustration only, not a quote.
The last column is where the real answer lives. Starting at 25 buys a year of protection for about $1,605. Starting at 55 buys a year of protection for about $4,136, which is 2.6 times as much. The total is lower because you bought less, in the same way that a shorter holiday is cheaper than a longer one.
Look at it from the other direction and the case for starting young gets stronger, not weaker. Adding the decade from 25 to 34 to a policy that would otherwise start at 35 costs a man an extra $4,681 across his whole life, or about $468 for each of those ten years, against an average of $1,983 a year on the 35-start policy. For a woman it is $3,159, or about $316 a year. Those are the cheapest years of cover anyone in New Zealand can buy.
The finding nobody explains: cheaper at 35 than at 25
On Canstar's grid a male non-smoker is quoted $39 to $46 a month for $500,000 of cover at 25, and $33 to $37 at 35. The price falls. Canstar publishes the grid and offers no explanation for it, and the pattern is not confined to that source: KiwiCover states that life cover premium rates typically decrease each year from about age 20 to age 30, and the AIA rate card on the same page runs $25.37 a fortnight at 20, down to $18.20 at 30, before climbing to $21.48 at 40 and $50.89 at 50.
| Age at issue | Male non-smoker, rate for age | Female non-smoker, rate for age |
|---|---|---|
| 20 | $25.37 | $16.67 |
| 30 | $18.20 | $13.00 |
| 40 | $21.48 | $18.52 |
| 50 | $50.89 | $42.09 |
| 60 | $159.18 | $118.20 |
| 70 | $602.10 | $383.10 |
Fortnightly AIA standard rates as at 20 March 2025 for $500,000 of life cover, non-smoker, including AIA's standard policy fee and excluding discounts, as published by KiwiCover. Published illustration only, not a quote.
Both sexes fall from 20 to 30 on that card. The AIA male rate drops 28 percent across the twenties and the female rate drops 22 percent. Whatever is happening, it is deliberate and it is priced into the rate table.
Why the price falls when the risk does not
Here is where most explanations reach for folklore, so we went to the mortality data instead. The Stats NZ national period life table for 2022 to 2024 gives the probability of dying within a year at every single year of age. For New Zealand men it is essentially flat from 24 to 31, at 75 to 77 deaths per 100,000, and it does not begin climbing properly until the mid thirties.

|---|---|---|
| 20 | 65 | 37 |
| 25 | 76 | 42 |

That flat stretch explains why the price does not rise through the late twenties. It does not explain why the price falls, and it is worth being honest that it points the other way: population mortality for a New Zealand man is lower at 20, at 65 per 100,000, than it is at 30, at 77 per 100,000. On population numbers alone, a 20-year-old should be cheaper than a 30-year-old, and on the rate card he is dearer.
No New Zealand insurer publishes the reason, so what follows is our reading rather than a sourced explanation. Insurers do not price population mortality. They price the mortality of people who have just passed a medical underwriting assessment, and underwriting is very good at screening out medical risk and useless against risk that is not medical. In the youngest adult band, most deaths are not medical. The Child and Youth Mortality Review Committee reports that across 2015 to 2019 suicide was the most common category of death for New Zealanders aged 15 to 19 and injury was the leading cause for those aged 20 to 24, with medical conditions leading only below age 15.
So a newly underwritten 20-year-old carries close to the full population risk, because the dominant causes at that age cannot be underwritten away. A newly underwritten 30-year-old carries a much lower risk than his population figure suggests, because a larger share of the deaths at his age are medical and the assessment has just filtered for them. Add a fixed policy fee that lands hardest on the smallest premiums, and a rate table that has to hold together across the whole of adult life, and a falling twenties rate stops being a mystery. We would rather say that plainly than repeat the standard line that buying younger always costs less per month, which the published grids simply do not support.
So what does waiting actually cost?
Four things, none of which is the total premium.
Years you are not covered. This is the largest one and it does not appear in any price table. A man who waits from 25 to 45 saves $10,231 across his life and spends twenty years during which his family would have received nothing. Life cover is not a savings product with a maturity date. Its value is entirely in the years it is in force.
A worse price per year of protection. As the table above shows, cover bought at 55 costs about 2.6 times as much per year of protection as cover bought at 25. That is the correct way to compare two policies of different lengths, and it is the comparison the industry should be making instead of the total.
The level premium option, priced out. Locking a rate for life is cheap when you are young and expensive when you are not. On AIA's published card, level to age 80 for $500,000 of cover costs a male non-smoker $50.43 a fortnight if he locks in at 30 and $156.03 if he waits until 50, a little over three times as much for the same guarantee. The full working on that decision is in where stepped and level premiums actually cross over.
Insurability. This is the risk that has no price at all until it lands, and then it has an infinite one. Every published figure on this page assumes a healthy applicant at standard rates. KiwiCover states that availability of cover is subject to underwriting and approval by the insurer, and Canstar lists health and medical history including pre-existing conditions among the factors that affect what you pay. A diagnosis between 35 and 45 can turn a routine application into a loading, an exclusion for the exact condition most likely to affect you, or a decline. Our guide to insurance premium loadings in NZ sets out how those decisions are made.
Is there ever a case for waiting?
Yes, and pretending otherwise is how people end up sold cover they cancel. Life insurance replaces income and clears debt for people who depend on you. If nobody depends on you and you have no debt anyone else would inherit, there is no obligation to insure, and buying at 22 to lock in a rate you do not need yet is a weaker argument than it sounds, because the rate you are locking is on a stepped policy that reprices every year anyway.
Two things do argue for buying before you strictly need to. One is health: cover taken out while you are well is underwritten on a clean file, and that file does not reopen later. The other is the level premium window, which closes expensively, as the AIA card shows. Between those two, the honest guidance is to buy when a dependant, a mortgage or a business obligation appears, and not to defer once one has.
The one thing that is genuinely urgent is a gap you already have. If someone would struggle financially if you died next month, the cost of waiting is not measured in dollars at all. Our life insurance calculator works out the size of that gap, and life insurance price by age in NZ shows what the cover costs at your age today.
Honest limits on this analysis
The totals in the first table are built by interpolating between price points ten years apart. Real rate tables step every year, and the true shape between Canstar's anchors will not be a perfectly smooth curve. The totals should be read as the size and direction of the effect, not as a bill.
Nothing here is discounted for inflation or for the time value of money, so a dollar paid at 60 is treated as equal to a dollar paid at 25. That flatters the later starter, because his money is spent in cheaper dollars. Insurer rate reviews are also ignored, and stepped premiums in New Zealand can be repriced across a whole book on top of the age-based increase.
Finally, every figure assumes the cover stays at $500,000 the whole way through, which almost nobody does. In practice sums insured rise with a mortgage and fall as it clears, and each increase is priced at your age on the day you ask for it, which is a second and less visible cost of waiting. Quashed's May 2026 Market Scan shows how much the price of the same cover varies between insurers at any age, which is the other half of the decision.

Frequently Asked Questions
Is it cheaper to get life insurance when you are young?
Per month, yes at most ages, and no in one window: published New Zealand rates for men can fall from about 20 to about 30. In total, buying young is always more expensive, because you pay for more years. The measure that matters is cost per year of protection, and on that measure starting at 25 is about 2.6 times better value than starting at 55.
How much does waiting ten years cost in NZ?
On Canstar's grid, waiting from 25 to 35 reduces a man's total bill to 65 by about $4,681 and a woman's by about $3,159, in exchange for ten fewer years of cover. Those ten years work out at roughly $468 a year for a man and $316 for a woman, which is the cheapest cover either of them will ever be offered.
Why is life insurance cheaper at 35 than at 25 for men?
Canstar's grid shows it and does not explain it, and AIA's published rate card shows the same fall from 20 to 30. Stats NZ mortality data shows the risk is broadly flat across that stretch, so there is no age effect for the insurer to charge for. Our reading is that underwriting screens medical risk but not injury and suicide risk, which is what dominates deaths in the youngest adult band.
When should I actually buy life insurance in NZ?
When someone would be financially worse off if you died: a partner, children, a co-borrower on a mortgage, or a business partner. Buying before that point is optional. Deferring after it is the expensive choice, and the expense is measured in exposure rather than in premium.
Does waiting affect whether I can get cover at all?
Yes, and this is the risk with no price attached. Cover is subject to underwriting and approval, and a condition diagnosed in the meantime can produce a loading, an exclusion for that condition, or a decline. A clean medical history is an asset that only depreciates.
Is it better to lock in a level premium young?
On the published rate card, yes if you intend to hold the cover for life. Level to 80 costs a little over three times as much per fortnight if you lock in at 50 rather than 30. Whether that is worth doing depends on where the cumulative cost crosses over, which is a separate calculation.
Do these totals include inflation?
No. Every figure is in nominal dollars, so a payment at 60 is treated the same as a payment at 25. Discounting would narrow the gaps and make the later starter look better still on total cost, which is another reason to judge the decision on cover per year rather than on the total.
