The headline number is a statistical trick
Worldline’s payments network recorded total card spending of $3.98 billion in March 2026, up 0.5% on March 2025. That figure was reported as evidence of consumer resilience. It is nothing of the sort.
Retail NZ chief executive Carolyn Young was blunt: “The 0.5 percent headline growth is a mirage,” she said. “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.”
The mechanism is simple. Petrol station spending surged 33% above year-ago levels by the end of March, driven by the Iran conflict’s oil price shock. Unleaded prices rose roughly 26% over the month; diesel roughly 70%. That single category swamped everything else. Treasury’s own fortnightly indicators confirmed it: nominal card spending lifted 1.3% in March but core retail spending excluding fuel and vehicles fell 0.1%.
More dollars, fewer goods
The deeper problem is that even the fuel spending figure overstates real activity. Fuel spending totalled $583 million in March, up 10.2% in dollar terms, but still below March 2024’s $591 million despite significantly higher prices. Infometrics estimates actual fuel volumes purchased fell around 3.6% year-on-year, and notes that fuel volumes have likely been declining for most of the last 2.5 years.
Westpac senior economist Satish Ranchhod made the consumer-side case plainly: “Per-person spending on Westpac issued debit and credit cards was essentially flat in March. And with prices pushing higher, that means many of us are getting less in our shopping baskets each time we go through the check out.”
This is the fundamental flaw in using electronic card transaction data as a health check. It measures dollars, not volume. When annual inflation is running at 3.1% with electricity up 12.5% and council rates up 8.8%, nominal spending can rise while real consumption shrinks.
Where the pain is landing hardest
The category data leaves no room for optimism. Apparel spending fell 4.2% year-on-year, the largest monthly drop since mid-2024. Hospitality fell $37 million, or 2.4%. Westpac’s own data showed a 2% drop in takeaways and restaurants.
The March fuel surge also included panic-buying that reversed immediately. April retail spending fell $160 million, or 1.6%, with consumables, hospitality, and durables all declining. By May, spending had fallen a further 0.2%, with Westpac noting it had been tracking sideways for three months.
Geographically, the two biggest consumer markets are pulling back hardest. Auckland annual spending growth fell 0.6% and Wellington fell 1%, while regional centres like Nelson (up 4.2%) and Palmerston North (up 3.8%) showed resilience. For retailers with national footprints, the recovery story in Nelson is not the story in Auckland CBD.
Business owners are not betting on a bounce
Survey data confirms the mood. A Research New Zealand survey of 433 business owners found 61% are not planning investment in the next 12 months, with 63% describing the economic situation as bad or very bad. Two percent plan to close outright and 14% plan to downsize. These are not cyclical adjustments. They are structural exits.
Treasury’s April indicators showed business confidence crashing from +39 to +1, its lowest since September 2024. Infometrics chief forecaster Gareth Kiernan cut his 2026 GDP growth forecast from 2.5% to 1.3%, with household spending growth projected at just 0.8%, barely above flat in real terms.
Every extra dollar at the pump is a dollar lost to a retailer
Young’s warning captures the bind perfectly: “Every extra dollar spent on transport is a dollar lost to a local retailer.” With 93% of New Zealand freight moving by road, elevated fuel prices hit retailers from both directions: their own cost base and their customers’ disposable income.
The nominal spending data, taken at face value, does not signal urgency. That is precisely the danger. Business owners making staffing, inventory, or investment decisions based on headline card spending figures are reading a thermometer that measures the wrong thing. The real economy, measured in what people actually take home in their shopping bags, is contracting. Acting as though it isn’t is the most expensive mistake a retailer can make right now.
