Something shifted in New Zealand's spending habits this February, and it's not just another headline about economic gloom.
Credit card spending across the country fell 1.1% year-on-year in February 2026, flipping from a 0.9% increase in January to the first negative reading since the COVID disruptions of 2020(1). All up, Kiwis put about $4.4 billion through their credit cards that month, with spending on New Zealand-issued cards inside the country dropping 0.2% month-on-month.
Here's the thing though. We talk to households and customers every day, and we get a pretty good sense of what's actually happening on the ground. What we're seeing is more nuanced than the simple "people are scared to spend" story most coverage is running with.
What we're actually seeing inside SortMe
Yes, there is fear in the economy. Petrol prices, the cost of living, global uncertainty - households are feeling the pinch and getting more conservative with their money. But credit card spending falling, specifically, tells a different story too.
We're seeing more households without credit cards than with them, and the national data backs it up. The number of active credit cards in New Zealand has fallen 8.7% since the start of 2019, down to around 2.05 million, and when you adjust for adult population growth the drop is closer to 14%. The share of Kiwis holding three or more active cards has collapsed from one in six to one in thirteen(2). That's a meaningful shift. And it's not because people can't get credit, it's because they're choosing not to use it. I believe Kiwis are waking up to the realities of the credit card ruse.
The enticement of rewards programmes simply doesn't stack up once you account for the extra spending a credit card drives. A landmark Dun & Bradstreet study found people spend 12-18% more when paying with credit cards instead of cash(3). That reward flight to Queenstown looks a lot less appealing when you realise you overspent by thousands to earn it.
And the rewards themselves have been quietly gutted. Kiwibank ended its Airpoints credit card programme entirely in October 2025, leaving an estimated 10,000+ cardholders to find alternatives(4). BNZ followed in February 2026 with a significant devaluation of its own rewards programme, with interest-free days dropping from 55 to 44, travel insurance scaled back, and earn rates cut(5). With interchange fee caps now in effect, bank-issued cards earn roughly one Airpoints Dollar per $110-$220 spent, compared to around $70 on American Express. For many households, the annual fee simply doesn't pay for itself anymore, and they're acting on it.
The psychology: why credit cards make you spend more
What we're seeing in SortMe lines up with decades of behavioural research. People are becoming more aware of the gamification credit cards bring, and the psychological impact it has on their spending habits.
Consider this: in MIT's famous silent auction for Boston Celtics tickets, credit card buyers bid more than twice as much as cash buyers(6). The psychological cost of spending a dollar on a credit card feels like only 50 cents.
It gets deeper. MIT Sloan research using fMRI brain scans found that credit card purchases activate the same dopaminergic reward centre, the striatum, that's exploited by addictive substances like cocaine and amphetamines(7). Credit cards don't just "release the brakes" on spending, they actively "step on the gas" by sensitising reward networks in the brain.
And here's the kicker: that reward activation was largely independent of price(8). The brain's response to swiping a card bore little relation to how much was being spent. Whether it's a $5 coffee or a $500 appliance, the neural reward hit is essentially the same.
That's a sobering finding. And I think more Kiwis are starting to intuitively understand what the neuroscience confirms.
Are Kiwis switching to debit, or just spending less?
It's both, but the shift to debit is a healthy signal, not a distress signal.
It's not surprising that credit cards are becoming less important for most New Zealand households. Unlike the United States, where your credit score is intimately tied to credit card usage and history, New Zealand doesn't run on the same credit score system(9). There's no compelling reason for most Kiwis to keep a credit card purely for credit-building purposes.
Households that manage money well simply don't need a credit card. Take it out of the equation and you remove the gamification, the disconnection between spending and paying, and the dopamine-driven overspend the research so clearly documents.
One thing worth watching, though: some of that short-term borrowing is shifting to Buy Now Pay Later rather than disappearing. BNPL has its own behavioural traps, arguably worse ones for younger users, and "I'm not using a credit card" isn't the same thing as "I'm in control." Ditching the card is a great start. Knowing where your money actually goes is what makes the change stick.
What this tells us about financial confidence in 2026
The decline in credit card spending isn't purely a sign of consumer retreat. It's also a sign that some households are getting smarter about how they spend.
In fact, there's one statistic that tells this story better than any other. Back in 2000, 72% of credit card balances in New Zealand were interest-bearing, meaning most Kiwis were carrying debt from month to month and paying for the privilege. By 2025 that figure had fallen to 51%(5). That's a 25-year trend of Kiwis learning to use cards more responsibly, or walking away from them altogether. It doesn't look like panic. It looks like progress.
The feeling of losing control of your spending is only made worse by having a credit card. Access to money you didn't earn, combined with the gamification of rewards and points, leads to more anxiety, not less. The only way to truly be in control of your finances is to not fall victim to the ruse, and to remember that earned money has more value than borrowed money.
In these times of uncertainty, with petrol prices volatile, groceries climbing and global trade policy creating ripple effects across the economy, it's more important than ever to live within your means, set savings aside, and cut back where you can. That discipline creates financial security and reduces financial stress.
Why visibility is the first step
This is exactly why we built SortMe. Not as a budgeting app that lectures you about your coffee habit, but as a tool that gives you real visibility into where your money is actually going.
SortMe helps households put together a financial plan and a budget that can curb the overspending a credit card brings. Knowledge is power, and understanding where your money is going is incredibly important to taking control of your finances.
When you can see every transaction categorised in real time, across every account, the credit card trick stops working. You can see the 12-18% overspend for what it is. You can compare months. You can spot subscriptions you forgot about. You can share the picture with your partner, or your financial advisor, and make decisions based on data, not gut feel.
The Kiwis ditching their credit cards are onto something. But visibility, not just willpower, is what makes the change stick.
