Do owners or renters spend more on housing in NZ?

On the housing and utilities category alone, renting households averaged $502.00 a week against $506.60 for mortgaged owners in the 2023 survey. But that comparison is incomplete by construction: the survey files mortgage INTEREST outside the housing category, under other expenditure, where mortgaged owners show $417.40 against renters' $75.30. Only with both categories together do the two tenures compare honestly.

What is the most misquoted number in the household spending data?

Rent averaged over ALL households, which mixes renters with the majority who pay no rent at all. It runs at roughly a third of what renting households actually pay, and it is quoted as the average rent depressingly often. The honest figure is rent over households in rented dwellings, which this site's spending pages use and label.

Why does the survey split a mortgage across two categories?

The classification treats principal repayments as a change in what you own rather than consumption, and interest as a finance cost rather than housing. Both land outside the everyday reading of the housing line. Anyone comparing owning against renting from the housing category alone is comparing a renter's whole housing cost against part of an owner's.

Which tenure is cheaper overall?

The survey cannot answer that, and this guide will not pretend it can. Owners and renters differ in age, income, household size and region, so their spending differences bundle who they are with what tenure costs. What the data does answer is what each group actually spends, category by category, which is the honest input to the rent-or-buy arithmetic done properly in the rent vs buy calculator.

Owner vs Renter Spending: the Split the Averages Hide

Most household spending figures are quoted as one national average, and for housing that average is close to meaningless, because it blends three groups whose housing costs share nothing: renters paying market rent, owners paying a mortgage, and owners paying neither. The survey publishes the split by tenure, and this guide is the corrections that make it readable.

Correction one, the misquoted rent. Rent averaged over all households runs at roughly a third of what renting households actually pay, because most households pay no rent. Any figure introduced as "the average household spends $X on rent" is this error wearing a suit. The honest line is rent over renting households, and every page in this site's spending section uses and labels it.

Correction two, the split mortgage. A mortgage payment does not appear as one line anywhere in the survey. Principal lands under a capital category and interest under other expenditure, neither inside housing. The housing category for a mortgaged owner is rates, insurance, energy and upkeep, which is why it reads implausibly low next to a renter's, and why comparing tenures from the housing line alone is comparing a renter's whole housing cost against part of an owner's.

The measured split, read with the corrections on

From the 2023 survey, the two categories that carry the tenure story:

Average weekly spend	Renting households	Owners with a mortgage
Housing and household utilities	$502.00	$506.60
Other expenditure (holds mortgage interest)	$75.30	$417.40

Read the first row and the two tenures look nearly identical, which should immediately feel wrong, and is: a renter's row holds their whole housing cost while the owner's holds rates, insurance, energy and upkeep with the mortgage absent. The second row is where the owners' interest surfaces, five times the renters' figure. Neither row alone is the housing cost of either group. The full category table for every tenure, including owners without mortgages and trust-held dwellings, is in the spending section.

Beyond housing, the tenure columns mostly tell a quieter story: the two groups' food, transport and communication lines sit far closer together than their housing lines, because tenure sorts people by life stage more than by lifestyle. Which is the third correction, and the biggest.

The comparison the data cannot make, and the one it can

The survey cannot tell you whether owning or renting is cheaper. Owners and renters are different people before they are different tenures: different ages, incomes, household sizes and regions. Their spending gaps bundle all of that with tenure itself, and no honest reading separates the strands. A guide that declared a winner from this table would be inventing the attribution.

What the data can do is give each side of the rent-or-buy decision its measured inputs. What renting households like yours actually pay is on the area pages, area by area. What owning actually costs beyond the mortgage, the rates, insurance and upkeep that surprise first buyers, is what the owner columns here measure. The rent vs buy calculator then runs the comparison forward properly, with your numbers rather than the averages'.

And one habit worth keeping from this page: whenever a housing figure is quoted at you, ask which denominator it stands on. All households, or the households who actually pay that cost? Most housing statistics arguments dissolve at that question.

Quiz on the tenure split

1. Why is rent averaged over all households a misleading figure?

Most households pay no rent, so the all-household average runs at roughly a third of what renting households actually pay

Because rents change too fast to measure

Because it excludes flatmates

It is not misleading; it is the standard figure

2. Where does mortgage interest sit in the survey's classification?

Inside housing, with rent

Under other expenditure, outside the housing category entirely

It is not collected

Split evenly across all categories

3. What is wrong with comparing tenures using the housing category alone?

It compares a renter's whole housing cost against part of an owner's, because the owner's mortgage sits outside the category

Renters are undersampled

The housing category excludes utilities

Nothing; that is the correct comparison

4. Can this data say whether owning or renting is cheaper?

Yes, owning wins clearly

Yes, renting wins clearly

No: owners and renters differ in age, income, size and region, so the gaps bundle who they are with what tenure costs

Only for Auckland

5. A housing statistic is quoted at you. What is the first question to ask it?

Which denominator it stands on: all households, or the households who actually pay that cost

Which political party released it

Whether it is in weekly or monthly form

Whether it includes GST

Frequently Asked Questions

Do renters or owners spend more on housing?

On the housing category alone, renters: $502.00 against $506.60 a week. But the owners' mortgage interest sits in another category, so only both rows together compare honestly.

What is the most misquoted number in this data?

Rent averaged over all households, which runs at roughly a third of what renting households actually pay because most households pay no rent.

So which tenure is cheaper?

The survey cannot attribute the difference between tenure and the people in it. The rent vs buy calculator answers the question the right way, forward, with your own numbers.
