How Many People Live Alone in New Zealand — and Who

How many people live alone in New Zealand

The most direct answer comes from the Stats NZ 2023 Census: 389,352 New Zealanders live alone, which is 22.8% of all households — more than one in five homes in the country contains a single person. Living by yourself is now one of the most common household arrangements in Aotearoa New Zealand.

Living alone spans every age group, but it concentrates among older adults. Of everyone who lives alone, 192,201 — 49.4%, almost exactly half — are aged 65 and over. So while a young person flatting solo and a widowed 80-year-old are both counted here, the single largest block of people living alone in New Zealand are older adults.

This page answers the population question. For the seniors-specific picture — the 25.3% rate among people 65+, the falls data and the discovery-gap risk in detail — see our companion page, New Zealand living alone statistics 2026: seniors and households.

Living alone rises steeply with age

22.8% of all households in New Zealand are one-person households, while 25.3% of people aged 65 and over live alone — about one in four older New Zealanders (Stats NZ 2023 Census). Those are two different denominators — a share of all households versus a share of people aged 65+ — but they point the same way: solo living is markedly more common in later life. And the older cohort itself is growing: 828,600 New Zealanders — 16.6% of the population, roughly one in six — are now aged 65 or over, and Stats NZ population projections put the 65-plus population past one million by 2028.

Two curves therefore point the same way. A larger share of older people live alone than the population as a whole, and the older population is expanding. The result is a solo-senior group that grows faster than the ageing of the country alone would suggest. Our seniors-and-households page breaks the 65+ figures down in full.

Most people who live alone are women

57.4% of New Zealanders who live alone are women (Stats NZ 2023 Census). The reason is demographic rather than behavioural: women, on average, outlive men, so the oldest age bands — where solo living is most common — contain more women, many of whom have outlived a partner. Widowhood and longer female life expectancy push in the same direction, and the typical older New Zealander living alone is a woman.

That overlap matters for safety planning. The people most likely to live alone are, on average, also the people most exposed to falls and sudden illness, and least able to get themselves to a phone afterwards — which is what turns a demographic fact into a practical question about who would notice if someone went quiet.

How New Zealand compares across the region

New Zealand's rate of solo living among older adults sits within a broadly similar band across the Asia-Pacific, though every statistics office publishes on a slightly different basis, so the figures are not perfectly like-for-like. New Zealand and Australia report a share of the 65-plus population; Singapore reports an absolute count. The fieldwork years differ too — 2021 for Australia, 2023 for New Zealand, 2025 for Singapore. Read the basis column before comparing the numbers.

Living alone, loneliness and the discovery gap are three different things

Living alone is a household arrangement, and for hundreds of thousands of New Zealanders it is a positive, independent choice. It is not the same as loneliness, which is the subjective distress of wanting more connection than you have — on the Stats NZ General Social Survey (2023), about 11% of New Zealanders aged 65+ said they had felt lonely at least some of the time. And living alone is not the same as the narrow safety risk this app addresses: the discovery gap.

The discovery gap is specific. If you live alone and something happens — a fall, a stroke, a cardiac event — there is no one in the home to notice and call for help. Falls make it concrete. ACC (2024) reports that around 30% of New Zealanders aged 65 and over fall at least once a year, and roughly 10-20% of those falls need hospitalisation. The Health Quality & Safety Commission's Atlas of Healthcare Variation recorded about 27,000 people aged 50 and over hospitalised with a fall (a figure from its 2016 Atlas, flagged here as older than the census data). The danger of a fall is driven less by the impact than by how long someone is left afterwards: a peer-reviewed cohort found that roughly half of older people who suffer a 'long lie' — more than an hour on the floor — died within six months (Wild, Nayak & Isaacs, BMJ 1981). For someone who lives with others a fall is noticed in minutes; for the 389,352 New Zealanders who live alone, it can be hours.

What the census counts as living alone

The figures on this page rest on a specific definition, and it is worth being precise about it. In the Stats NZ 2023 Census, someone who lives alone is counted as a one-person household — a private, occupied dwelling whose only usual resident is that single person. That is a fact about a home, not about a person's social life: it does not ask whether anyone visits, whether family live nearby, or whether the person feels alone.

The 389,352 figure is therefore a count of homes with exactly one usual resident, and the 22.8% is those homes as a share of all occupied private dwellings. When we then say 25.3% of people aged 65 and over live alone, the denominator has changed — it is now a share of people in that age band, not a share of households. Keeping the two denominators apart is the single most common mistake in reading living-alone statistics, so every figure here is labelled with the base it is drawn from.

A daily check-in for New Zealanders living alone

The data on this page describes a specific, solvable gap: a large and growing number of New Zealanders live alone, falls are common in later life, and the worst outcomes come from being left undiscovered. I'm Alive is built for that gap. Instead of hardware, a pendant or a camera, you confirm you're okay once a day; if you don't, the people you chose are told.

The emergency number in New Zealand is 111 for ambulance, fire and police. A check-in app does not call 111 and does not pretend to — what it does is make sure that if you go quiet, the people you chose find out quickly.

I'm Alive is a daily check-in app that works on iPhone and Android, anywhere in the world. The daily check-in is free (Check In, $0) and includes one emergency contact — who is alerted if you go quiet, capped at one alert a month (push and email, no SMS). Stay Protected ($29.99/year) lifts that cap to unlimited alerts with full push, email and SMS escalation, and raises you to up to ten contacts; Complete Safety Net ($39.99/year) adds your last-known location on an alert, where available. On how often you check in, Stay Protected allows up to two and Complete Safety Net up to three scheduled check-in times a day, while Free and the one-time Stay Connected & Travel Safely upgrade ($4.99) stay at one a day. Your contacts hear from us only if you go silent — never on a successful check-in. Check-first phone fall detection is available on iPhone only, on Stay Protected and above; it stays off until you switch it on, only runs while the app is open, and alerts your own trusted contacts rather than calling emergency services — it is best-effort, not a medical device.
