Life Insurance Price by Age in NZ: The Whole Curve, Charted
A non-smoking New Zealand woman pays about $25 a month for $500,000 of stepped life cover at age 25 and about $443 a month for the same cover at 65, on the five-provider grid published by Canstar New Zealand (published 3 September 2024, page last updated 19 August 2026). That is roughly eighteen times the price for exactly the same policy. This page charts every published point on that curve and says where it turns.
The curve matters more than any single number, because almost nobody buys life cover for one year. You buy it for a stretch of your life, and the shape of the line decides what that stretch costs. The shape is not a steady climb. It is flat, then it bends.
What does $500,000 of life cover cost at each age in NZ?
Published New Zealand prices for $500,000 of stepped life cover run from about $22 a month for a 25-year-old non-smoking woman to about $1,402 a month for a 65-year-old male smoker. Canstar reviewed quotes obtained online from five leading providers and published the approximate range each age, gender and smoking profile fell into. The chart below plots the midpoint of each of those ranges.

Here is the same grid as Canstar published it, in full ranges rather than midpoints.
| Age | Female, non-smoker | Female, smoker | Male, non-smoker | Male, smoker |
|---|---|---|---|---|
| 25 | $22 to $28 | $37 to $46 | $39 to $46 | $65 to $76 |
| 35 | $26 to $30 | $48 to $52 | $33 to $37 | $67 to $78 |
| 45 | $50 to $59 | $102 to $117 | $59 to $67 | $134 to $167 |
| 55 | $132 to $158 | $265 to $321 | $160 to $195 | $371 to $464 |
| 65 | $397 to $489 | $715 to $828 | $600 to $726 | $1,209 to $1,402 |

Where does the curve actually accelerate?
The price barely moves between 25 and 35, then roughly doubles over the next decade, then roughly triples over each decade after that. On Canstar's midpoints a non-smoking woman's cover rises 12 percent between 25 and 35, then 95 percent from 35 to 45, then 166 percent from 45 to 55, then 206 percent from 55 to 65. The male non-smoker line does something stranger still, which the next section deals with.
Stated as a compounding rate, the same grid gives this.
| Decade | Female non-smoker | Male non-smoker | What the price does |
|---|---|---|---|
| 25 to 35 | 1.1% a year | Falls 1.9% a year | Effectively flat, and negative for men |
| 35 to 45 | 6.9% a year | 6.1% a year | Doubles about every 10 to 12 years |
| 45 to 55 | 10.3% a year | 10.9% a year | Doubles about every 7 years |
| 55 to 65 | 11.8% a year | 14.1% a year | Doubles about every 5 to 6 years |

That table is the useful part of this page. The doubling interval halves as you age: about eleven years if you are 35, about seven if you are 45, and about five for a man of 55. It is the same policy and the same sum insured throughout. Only the age used to price it has changed.
A second published rate card shows the same bend. KiwiCover publishes AIA's standard premium rates as at 20 March 2025 for $500,000 of life cover on a rate-for-age basis, and for a male non-smoker they run $25.37 a fortnight at age 20, $18.20 at 30, $21.48 at 40, $50.89 at 50, $159.18 at 60 and $602.10 at 70. Those are single-insurer rates rather than a five-provider range, and they still fall through the twenties, crawl through the thirties and then climb at 9 percent a year in the forties, 12 percent in the fifties and 14 percent in the sixties.
Why does the male non-smoker line fall between 25 and 35?
Because it does, on more than one published New Zealand price list, and no comparison site explains it. Canstar's male non-smoker range is $39 to $46 a month at 25 and $33 to $37 at 35. The midpoint falls 18 percent over a decade in which every other line on the grid rises. Zooming in makes it obvious.

This is not a printing error, and it is not unique to Canstar. KiwiCover states plainly that life cover premium rates typically decrease each year from about age 20 to age 30, and the AIA rates on the same page bear that out for both sexes: $25.37 a fortnight at 20 falling to $18.20 at 30 for a male non-smoker, and $16.67 falling to $13.00 for a female non-smoker.
The short version is that mortality risk for a young adult does not behave the way people assume, and the pricing follows it. We have set out the full mechanism, with the Stats NZ life table behind it, in the cost of waiting to buy life insurance in NZ. The practical consequence for this page is narrower: if you are a man in your twenties comparing quotes, the number you are shown is not the low point of your curve, and treating it as one will mislead you about what waiting costs.
What does the gender gap do as you age?
It is widest in your twenties, narrowest in your forties, and widens again from 55. On Canstar's non-smoker midpoints a 25-year-old man pays 1.70 times what a woman of the same age pays, falling to 1.25 at 35 and 1.16 at 45, then rising back to 1.22 at 55 and 1.50 at 65. Most coverage describes the gender gap as a fixed fact about life insurance. It is not fixed. It is a curve of its own.
| Age | Female non-smoker | Male non-smoker | Male price as a multiple |
|---|---|---|---|
| 25 | $25 | $43 | 1.70x |
| 35 | $28 | $35 | 1.25x |
| 45 | $55 | $63 | 1.16x |
| 55 | $145 | $178 | 1.22x |
| 65 | $443 | $663 | 1.50x |

MAS attributes the gender difference to different life expectancies between men and women, which is the right general answer but not a complete one, because a single life expectancy figure cannot produce a gap that narrows and then widens. What produces that shape is the underlying pattern of when men and women actually die at each age, which is not smooth.
Does the same shape hold on other published NZ price lists?
Yes, on both of the other published New Zealand grids we could find. Quashed publishes live quotes from its Market Scan for three named insurers at ages 30, 40 and 50, and its May 2026 figures for a male employed non-smoker with $500,000 of cover show the same flat-then-steep shape.
| Insurer | Age 30 | Age 40 | Age 50 | 30 to 40 | 40 to 50 |
|---|---|---|---|---|---|
| Pinnacle Life | $30.92 | $35.98 | $87.08 | 1.16x | 2.42x |
| AIA (Starter) | $39.57 | $46.67 | $110.39 | 1.18x | 2.36x |
| Partners Life | $39.00 | $45.09 | $112.64 | 1.16x | 2.50x |

Three sources, three methods, one shape. A decade of your thirties adds about a sixth to the price. The following decade multiplies it by roughly two and a half. If you want the same analysis by insurer rather than by age, our guide to how much life insurance costs in NZ sets out the full published tables, and average life insurance premiums in NZ collects four separate published grids side by side.
What the age curve does not tell you
It does not tell you what you will pay, and it is worth being blunt about that. Every figure on this page is a published illustration for a healthy applicant in a standard occupation. New Zealand life insurance is individually underwritten, and the insurer sets your premium after assessing your health, medical history, job and hobbies. That assessment can add a percentage loading, attach an exclusion, or occasionally decline the application, and no published grid models any of it. Our guide to insurance premium loadings in NZ covers how those decisions are made.
Three more limits are worth naming. Canstar's grid is stepped cover only, so it says nothing about what a level premium would cost at the same age, which is a different curve entirely and often a better buy. Ranges across five providers hide which provider sits where, so the spread you see is a market spread rather than a price you can pick from. And the ages are ten years apart, so the lines between the plotted points are drawn straight when the real rate table steps every year.
One small thing about the source deserves flagging, because it affects how much weight to put on the annual figures. Canstar states that a non-smoking man in his thirties can expect to pay "around $35 a month ($504 per year)". Thirty-five dollars a month is $420 a year, not $504. The monthly figure matches the grid and the annualisation does not, so use the monthly numbers and do your own multiplication.
What actually changes your price
Age is the strongest single driver on a stepped policy, because the rate is recalculated against your age every policy anniversary. Canstar lists the full set as age, gender, smoking status, health and medical history including pre-existing conditions, job and any associated risks, pastimes and hobbies, how you buy the cover, your choice of cover, and the amount of cover.
Two of those are worth acting on, and both are covered in depth elsewhere on this site. Smoking status is the largest single lever most people can pull, and the gap it creates is not the flat doubling most articles claim; we have charted it in smoker versus non-smoker life insurance in NZ. Premium structure is the other, because choosing level rather than stepped freezes the age used to price your policy; the maths and the crossover point are in stepped versus level premiums and where they cross.
If you want to know how much cover you need before you price it, that is a separate calculation and it should come first. Our life insurance calculator runs it with your own numbers, and the longer walkthrough sits in what drives life insurance premiums in NZ.

Frequently Asked Questions
At what age does life insurance start getting expensive in NZ?
On the published grids, around 45. Between 25 and 35 the price is close to flat. Between 35 and 45 it roughly doubles. From 45 the compounding rate crosses 10 percent a year, which halves the doubling interval to about seven years, and from 55 it shortens again to about five or six years for a man.
Does life insurance get cheaper as you get older?
Only in one narrow window. Published New Zealand life rates can fall from about age 20 to age 30, which is why a male non-smoker sits lower on Canstar's grid at 35 than at 25. After 30 the price rises every year on a stepped policy, and the rises accelerate.
Why is life insurance cheaper for women in NZ?
Every published New Zealand grid we reviewed shows lower prices for women at the same age, cover amount and smoking status. MAS attributes it to different life expectancies. The size of the gap moves with age, from about 1.7 times at 25 down to about 1.16 times at 45 and back up to about 1.5 times at 65.
Is the price locked in when I take out the policy?
Not on a stepped or rate-for-age policy. The premium is recalculated at each policy anniversary against your age at that date, so the curve on this page is the curve you ride. On a level policy the age used is frozen at the day you applied, which is a different and usually higher starting price.
Should I buy at the bottom of the curve?
The bottom of the curve is not the same as the cheapest place to buy, and the two get confused constantly. Buying at 30 means paying for more years than buying at 45, so the total is higher even though the monthly price is lower. What buying young actually buys you is a lower price per year of protection and the ability to be underwritten while healthy.
Do these prices include a policy fee?
Sometimes. The AIA rates published by KiwiCover explicitly include AIA's standard policy fee and exclude discounts. Canstar does not state whether its ranges include fees. A fixed policy fee matters most at small sums insured and young ages, because it is a larger share of a small premium.
