Vehicle Sales and Trade-Ins: what NZ households spend per week
Stats NZ publishes this category as Sales and trade-ins of vehicles, vehicle parts and accessories, within Sales, trade-ins and refunds. It is called Vehicle Sales and Trade-Ins here because that is what it is, but every figure on this page is the official category.
What this category covers
Money received from selling or trading in a vehicle, along with receipts from selling vehicle parts and accessories. A trade-in counts at its allowance rather than as a reduction in the price of the replacement.
What it does not cover
Buying a vehicle is vehicle purchases, recorded at full price. Insurance payouts on a written-off vehicle are recorded with insurance claims.
Those boundaries are set by the survey's own classification, not by us. They matter because a figure read against the wrong definition is worse than no figure: it looks precise and it answers a different question. If you are comparing your own spending against this page, check the exclusions above first.
How to read the figure
The largest single item in this group and the one that most affects how the transport figures should be read. Because purchases are recorded gross, the true net cost of changing vehicles is the purchase figure less this one. One household in twelve records a sale, and the amount received is a meaningful offset against the vehicle purchase line.
Every survey year
The Household Economic Survey runs every three years. This is sales and trade-ins of vehicles, vehicle parts and accessories in each survey since 2007, for all New Zealand households. Amounts are money received by the household, which the survey records as negative expenditure.
The figures are in the money of each survey year itself, so comparing 2007 with 2023 compares two different dollars. There is no column restating them in current dollars, because the Consumers Price Index has no series matching sales, trade-ins and refunds: the CPI measures the prices of things bought, and this category is not a purchase of goods or services. Part of any rise below is inflation, and nothing here can tell you how much.
The reporting column is the share of surveyed households that recorded any spending in this category at all: the lower it is, the further the average sits from what a household that does spend here actually pays.
| Survey | Published per week | Sampling error | Households reporting | Change |
|---|---|---|---|---|
| 2007 | $12.90 | ±41% | 10.1% | — |
| 2010 | $7.70 | ±23% | 8.4% | -40% |
| 2013 | $11.80 | ±31% | 9% | +53% |
| 2016 | $17.20 | ±47% | 9.5% | +46% |
| 2019 | $15.20 | ±20% | 10.2% | -12% |
| 2023 | $16.60 | ±21.2% | 8.1% | +9% |
Vehicle Sales and Trade-Ins over time
Each bar is one survey, in the money of its own year. There is no CPI series that matches this category for every survey year, so the bars are not restated in today's dollars and part of any rise you see is inflation rather than a change in what households buy.
The survey records this category as negative expenditure, because it is money coming into the household rather than going out. Bars show the amount received.

The dark line with a cap at each end shows the sampling error Stats NZ publishes with that figure: the survey is confident the true value lies within it. A long line means a less certain number. Bars in a pale fill are survey years whose sampling error is above the level at which this site normally withholds a figure. They are drawn here because the direction of a series is worth seeing even where the level is not reliable enough to quote, and the table above gives the error on each one.
By tenure
Whether a household owns or rents correlates with age, income and household composition, so a difference here is not caused by tenure alone.
The survey records this category as negative expenditure, because it is money coming into the household rather than going out. Bars show the amount received.
$0$28.14
Not shown, because the survey sample was too small to report reliably: Owned, mortgaged, Owned, no mortgage, Not owned, Renting, pays rent, Family trust, Trust, mortgaged, Trust, no mortgage.
Nothing to chart for Renting, no rent, because the survey recorded no spending in this category there at all. That is a measured zero rather than a figure withheld for uncertainty.
The dark line with a cap at each end shows the sampling error Stats NZ publishes with that figure: the survey is confident the true value lies within it. A long line means a less certain number.
Breakdowns that cannot be reported
Too few surveyed households recorded spending in this category for these breakdowns to be published at a sampling error under 30 per cent: by household size, by region, by household income. They are named here rather than left out, because a missing section reads as an oversight and a suppressed one reads as what it is. The sales, trade-ins and refunds page reports the same breakdowns for the wider category, where the sample is large enough.
The rest of sales, trade-ins and refunds
These are the other components of the same top-level category. They add up, with this one, to the total on the Sales, trade-ins and refunds page.

Where these numbers come from
Every figure on this page is from the Stats NZ Household Economic Survey, retrieved through the Aotearoa Data Explorer, for survey years 2007 to 2023. Inflation adjustments use the Stats NZ Consumers Price Index to the 2026.06 quarter. Stats NZ data is used with attribution; the survey figures are theirs and the adjustments are ours.
Household Economic Survey figures are averages of weekly household expenditure and carry the sampling errors shown. They are averages rather than medians, so they are pulled upward by the highest spenders. Figures are rounded as published.
