What It Actually Costs to Live in New Zealand
Cost-of-living numbers in public argument are usually one of two things: an inflation rate, which measures change and not level, or a constructed budget for an imaginary person. There is a third kind, better than both and barely quoted: what real households actually spent, measured by Stats NZ across thousands of spending diaries. This guide is that number, and how to use it.
The level, from the 2023 survey, summed across the categories published cleanly for every household size (3 categories with suppressed cells are left out of every column, so the columns compare like with like):
| Household size | Average weekly spending | A year |
|---|---|---|
| One person | $817.70 | $42,520 |
| Two people | $1,527.80 | $79,446 |
| Three people | $1,822.70 | $94,780 |
| Four people | $2,194.60 | $114,119 |
Two reading rules carry through everything. These are averages, pulled up by high spenders, so a typical household sits somewhat under its row. And they are 2023 prices, because the survey runs every three years: use the structure and the ratios with confidence, and the levels as a floor to inflate rather than this week's bill.
Where the money actually goes
The largest single category is Housing and household utilities, and it is also the least average-able: it blends renters paying full market rent, mortgage payers, and outright owners paying only rates and upkeep, three groups whose real housing costs have almost nothing in common. Whatever your situation, your own housing line will sit far from the average, in a direction you already know. That is not a flaw in the data; it is the reason to compare by line rather than by total.
Food and transport follow, and together the top three categories take roughly half of all household spending. The remaining half spreads across ten categories, none dominant, which has a practical meaning for budgeting: below the top three, no single line rescues a budget. Cutting subscriptions matters, but the categories where the money is are housing, food and transport, and the guides on each, food, the rent and commute trade, are where the leverage lives.
Every category, and every line inside it, has its own page in the household spending section, with history back to 2007 and the split by size, region, tenure and income.
The shape that matters: people share badly
Run a finger down the table above and the striking thing is how slowly the total grows with the household. Two people do not cost twice one person; four do not cost twice two. The dwelling, the power connection, the car and the insurance are household costs, not per-person costs, and only food and clothing scale with heads.
That single fact drives most of the practical conclusions in this data. Flatting is cheap because it spreads household costs across more people. Living alone is the most expensive ordinary arrangement in the country per person. A couple separating does not halve each person's costs, it nearly doubles the total, which is why the retirement guide makes so much of what happens when two becomes one. And a household growing by a child adds far less than a household splitting subtracts.
The same logic, run against where you live rather than how many you are, is the regional guide: regions differ mostly in housing, sizes differ mostly in everything else.
Turning the benchmark into a budget
The wrong use of this data is comparing your total against the national total, which mostly measures household size and tenure. The right use is line by line, for your household size, which the budget calculator automates: enter your own lines and the measured benchmark for a household like yours appears beside each one, adjusted for size, region and tenure.
Read the gaps with the classification in mind before reading them as behaviour. A takeaway coffee is not groceries; juice is a beverage, not fruit; a mortgage splits across two categories. Most shocking comparisons soften once the lines are matched properly, and the ones that survive matching are the real findings.
And keep the one-sentence version of this whole guide: averages, 2023 prices, households share badly, and the money is in the top three categories. A budget built on those four facts is built on measurement, which beats every rule of thumb in circulation.

How much does it cost to live in NZ per week?
About $817.70 for one person, $1,527.80 for two, $2,194.60 for a family of four, on the 2023 survey's comparable categories. Averages, so typical households sit somewhat under.

Housing and household utilities, followed by food and transport; the three together take about half of household spending.
Where do I check one specific line?
The household spending section holds every category and sub-line with history to 2007, and the budget calculator puts the right benchmark beside each line you enter.
