The mirage in the March numbers
Stats NZ electronic card data for March 2026 showed headline retail spending up 0.5%. That number has been widely cited as evidence of consumer resilience. It is evidence of nothing of the sort.
Retail NZ chief executive Carolyn Young was blunt: ‘The 0.5 percent headline growth is a mirage. Our analysis has found that behind that figure, fuel is doing the heavy lifting. If you account for that rise in fuel spend, we estimate core retail spending actually dropped by 1.2 percent year-on-year.’
Worldline data recorded a 33% surge in petrol station transactions in March. Westpac senior economist Darren Gibbs confirmed the dynamic: ‘Increased spending on fuel was responsible for an overall lift in spending in March,’ with petrol prices jumping almost 19%. Strip the fuel out and the retail economy is contracting.
By May, the picture had worsened. Stats NZ showed retail spending fell 0.2%, or $9.9 million, with Westpac senior economist Satish Ranchhod noting spending had been ‘effectively tracking sideways for the past three months.’
$55 a week that never reaches a shop
ASB economists estimate the current oil shock adds about $55 a week to average household costs through 2026. That money goes to fuel companies and OPEC producers, not to the cafe down the road.
The cruel detail is that Kiwis are driving less and paying more. Retail NZ’s analysis shows fuel spending totalled $583 million in March, up 10.2% in dollar terms but still below March 2024’s $591 million despite 91 unleaded rising from $2.80 to $2.98 per litre. Westpac estimates the actual volume of fuel purchased is down 6% to 8%.
The sectors absorbing the blow line up in order of dispensability. Apparel spending fell 4.2% year-on-year in March. Hospitality is taking significant hits, with Westpac recording falls in restaurant and takeaway spending. By May, durables fell 0.5% and consumables declined 0.1%. Rising food prices are compounding the squeeze, with Ranchhod noting the cost of basics like butter and milk rising sharply.
A recovery aborted at exactly the wrong moment
Infometrics chief forecaster Gareth Kiernan has cut the 2026 GDP growth forecast to 1.3%, down from 2.5% before the fuel shock. Household spending growth is now projected at just 0.8% for the year. Inflation is heading to 4.8% in the current quarter, creating a stagflationary dynamic where businesses pass on cost increases into weakening demand.
There was a recovery building. NZIER’s Christina Leung noted in January that ‘firms are finally starting to see an improvement on demand’ after a prolonged gap between sentiment and actual conditions. The fuel shock arrived at precisely the moment that nascent confidence was translating into real activity, and it may have killed it.
Treasury’s November 2025 economic update had already shown the services PMI in contraction every month since February 2024. Net migration had collapsed to 12,400 annually by September 2025, around 30% of the prior year’s 42,400, shrinking the demand base. The economy was fragile before petrol prices surged. Now it is being asked to absorb a supply shock with no buffer.
What business owners should be planning for
The transmission from household caution to business revenue is direct and unavoidable. Young put it plainly: ‘Every extra dollar spent on transport is a dollar lost to a local retailer.’ With 93% of New Zealand freight moving by road, higher fuel costs feed into the price of virtually everything.
Regional divergence is emerging. Westpac data shows rural areas like Southland, Northland, and Canterbury holding up better on firmer commodity prices, while Auckland and Wellington are seeing the sharpest discretionary pullback. A BNZ survey found nearly half of households felt more financial pressure than usual at the start of 2026.
Mortgage repricing offers some hope. Ranchhod notes nearly half of all mortgages are due to reprice in the next six months, which should free up household cash. But his conclusion is sobering: recovery will be gradual.
Gibbs warned that ‘high fuel prices will continue to siphon money out of households’ pockets and add to production costs’, reshaping spending patterns rather than simply pausing them. Business owners reading the headline card data and seeing stability are reading a number that lies. The real economy, the one where people buy clothes and eat at restaurants and hire tradespeople, is shrinking. Planning for a snap-back is planning for something that may not come.
