Life expectancy in New Zealand: the number everyone quotes, and the one that applies to you

New Zealand publishes two different life expectancy figures, and they disagree by up to nine years. The one in every headline is the period measure: 80.1 years for males and 83.5 for females, based on death rates in 2022–2024 (Statistics New Zealand, National and subnational period life tables: 2022–2024, released 30 July 2025, retrieved 9 September 2026).
That number describes nobody who is currently alive. It is what a life would average if a person spent their whole existence experiencing the death rates of 2022–2024 at every age, all at once, which no one does. Stats NZ publishes a second set of tables that follows real birth cohorts, and says plainly that these "give the most authoritative measure of life expectancy" (Statistics New Zealand, New Zealand cohort life tables: March 2026 update, released 27 March 2026, retrieved 9 September 2026).
On that measure a baby born in the early 2020s can expect to reach about 89 if male and 92 if female.
The two measures, side by side
| Measure | Male | Female | What it describes |
|---|---|---|---|
| Period, at birth, 2022–2024 | 80.1 years | 83.5 years | A hypothetical life lived entirely at today's death rates |
| Cohort, born early 1960s | about 79 years | about 83 years | People turning 65 about now |
| Cohort, born early 2020s | about 89 years | about 92 years | Babies born today |
| Cohort, born late 1870s | about 51 years | about 55 years | The earliest data Stats NZ holds |

What it looks like if you have already reached 65
Life expectancy at birth is the wrong question for anyone old enough to be thinking about it, because it includes everyone who died young. The useful figure is how long you can expect to live given you have already got here, and Stats NZ publishes that too.
| Born | Remaining years at 65, male | Remaining years at 65, female |
|---|---|---|
| Late 1870s | about 13 | about 15 |
| Early 1960s | about 21 | about 24 |
| Early 2020s | about 26 | about 28 |
Stats NZ cohort life tables, March 2026 update, released 27 March 2026, retrieved 9 September 2026.
A man born in the early 1960s is turning 65 around now. His cohort can expect another 21 years, which takes him to 86. The headline period figure said 80.1. The gap between those two numbers is nearly six years, and it falls exactly where a life insurance decision gets made.
Why this is the most expensive statistic to misread
A level term policy is bought to a fixed age, commonly 80. Someone reading that male life expectancy is 80.1 concludes the cover outlasts him. On the cohort measure it does not: it ends about six years before the median outcome for his birth year, at the age where the reason he bought it is closest at hand.
That is not an argument for any particular product, and it is not advice. It is an argument for using the right table. If you are deciding how long cover needs to run, the period number is the wrong input and the cohort number is the one Stats NZ itself describes as most authoritative.
What changed in the latest release
The 2022–2024 period tables record the slowdown rather than the usual improvement.
- Life expectancy at birth increased by 0.2 years for males and did not change at all for females compared with 2017–2019.
- That is the smallest five-yearly increase since the 1960s.
- The difference between male and female life expectancy narrowed.
- Life expectancy increased for Māori while stalling for most other ethnic groups, and Stats NZ headlines that Māori recorded the highest increases.
- Increased death rates contributed to lower Pacific and Asian life expectancy.

Where you live changes it
Period life expectancy at birth was highest in the Tasman region for both sexes, at 82.8 years for males and 85.7 for females, and highest in the least deprived areas of New Zealand (Stats NZ period life tables 2022–2024, released 30 July 2025, retrieved 9 September 2026).
The deprivation finding is the larger one. Stats NZ publishes life tables by NZDep index, and the gradient across those is wider than the gap between the best and worst regions.
The shape of the series, described
Plotted from 1950–1952 to the present, both lines climb steeply and almost straight for fifty years, male and female roughly parallel with females consistently above. From about 2000 the male line rises slightly faster than the female one, so the gap between them narrows from around six years to around three and a half. In the most recent period both lines flatten: the female line is level and the male line barely rises. On a chart running from 65 to 85 years, that flattening is the first visible pause in seventy years of climbing.
What is not published
Stats NZ does not publish a life expectancy figure for people who hold life insurance, and no New Zealand insurer publishes the mortality experience of its own book. So there is no public answer to the obvious next question, which is whether insured lives differ from the population. They almost certainly do, because underwriting selects for health, but the size of that difference is not published by anyone in New Zealand and we are not going to estimate it.
Questions
Is New Zealand life expectancy still rising?
Barely, in the latest period figures. Male life expectancy rose 0.2 years and female did not move, the smallest five-yearly increase since the 1960s. The long-run cohort series still rises steeply, because it reflects seventy years of accumulated improvement rather than the most recent three.
Which number should I use when deciding how long cover should last?
The cohort figure for your birth years, and specifically the remaining-years-at-your-age version. Stats NZ describes cohort tables as the most authoritative measure, and they are the only ones that describe actual people rather than a hypothetical life lived at one moment's death rates.
Why is the period figure lower than the cohort figure?
Because the period measure assumes death rates never improve again. It applies today's rates at every age, so it bakes in none of the improvement that has happened every decade for a century. The cohort measure includes projected improvement, which is why it is higher and why Stats NZ prefers it.
Do women still live much longer than men?
Less than they did. The gap has narrowed to about 3.4 years on the period measure, from around six years at the start of the century, because male life expectancy has been improving faster.

Adviser's view
QuoteHub built this page because the gap between the two measures is the single most expensive misunderstanding in life insurance planning. A man of 65 today reads that male life expectancy is 80.1, concludes he has fifteen years left, and buys a policy that ends at 80. Statistics New Zealand's own cohort tables, which it calls the most authoritative measure, say his cohort can expect another 21 years. The policy expires six years before the median outcome, at exactly the age it was bought to cover.
