Pay them bugger all, unless they do what they're required
Across New Zealand, savings accounts advertise interest rates that dissolve the moment life intervenes — a single withdrawal, a missed deposit, and the promised return collapses to near nothing. The structure, now standard among major banks, was once designed to reward disciplined saving, but has quietly inverted into a mechanism that captures the most from those who can least afford to lose it. As household budgets tighten, the gap between what banks promise and what ordinary savers actually receive is drawing fresh scrutiny — a quiet reckoning with who the financial system is truly built to serve.
- Savers who make even one withdrawal from ANZ or ASB bonus accounts can lose up to 1.55 percentage points of interest — a penalty that costs a typical household roughly eighty dollars a year for simply needing their own money.
- The design disproportionately punishes smaller savers who live closer to financial edges, while wealthier customers — better able to leave funds untouched — capture most of the advertised returns.
- Industry veterans describe a slow inversion: what began twenty-five years ago as a genuine incentive to save has become, in one executive's words, a system that pays customers 'bugger all' unless they behave exactly as the bank requires.
- Kiwibank and BNZ have rejected the bonus model entirely, offering single unconditional rates — a quiet but pointed challenge to the industry norm.
- Regulators are beginning to ask whether these account structures cross the line into unfair consumer practice, particularly as economic pressure makes the fine print harder for ordinary families to navigate.
Walk into any New Zealand bank and the advertised savings rates look generous — ANZ at 1.55 percent, ASB at 1.6 percent. But the fine print tells a different story. Make a single withdrawal, miss one monthly deposit, and the rate collapses to 0.05 percent. For a household with five thousand dollars saved, that gap costs around eighty dollars a year — money lost not through carelessness, but because life didn't cooperate with the bank's conditions.
Kiwibank's chief customer officer Mark Stephen puts it plainly: when an unexpected bill arrives or a car breaks down, savers lose their bonus through no fault of their own. The product, he argues, is built around an assumption of perfect monthly behaviour — and punishes people precisely when they need their savings most. Kiwibank and BNZ are the only major banks that don't operate this way, instead offering a single rate customers actually receive regardless of how often they dip into their accounts.
The model wasn't always so lopsided. David Cunningham, CEO of Squirrel and a former bank executive, recalls when bonus accounts were introduced around twenty-five years ago, with base rates near twelve percent and modest bonuses on top — a genuine nudge toward disciplined saving. Over time, the logic inverted: base rates fell to near zero, and meaningful returns were reserved only for those who met strict conditions. The original purpose gave way to a structure that benefits the bank far more than the customer.
The data reflects this imbalance. Roughly half of bonus account holders earn the advertised rate in any given month — but those customers hold about eighty percent of total funds. Wealthier savers, less likely to need emergency access, capture most of the returns. Smaller savers lose the bonus more often and are left earning almost nothing. ASB defends the structure as encouraging saving and notes it has reached out to over 190,000 customers about alternatives — but the underlying tension remains: a savings account that penalises access is, in practice, something other than what it appears to be.
Walk into any New Zealand bank and you'll find savings accounts advertising interest rates that look generous on the surface. ANZ promises 1.55 percent. ASB dangles 1.6 percent. The catch arrives in the fine print, where the real terms live: make a single withdrawal, miss a monthly deposit, or let life interrupt your perfect savings discipline, and that rate vanishes. You'll drop to 0.05 percent instead—a return so small it barely keeps pace with inflation.
This is the structure of bonus saver accounts, products that have become standard across the New Zealand banking system. The mechanics are simple enough. ANZ requires customers to deposit at least twenty dollars each month and make no withdrawals to earn their advertised rate. ASB's version is even stricter: any withdrawal at all forfeits the bonus. Miss the conditions by even one transaction, and the interest rate collapses to a fraction of what was promised. For a household with five thousand dollars in savings, the difference between 1.6 percent and 0.05 percent amounts to roughly eighty dollars a year—money that simply disappears because life didn't cooperate with the bank's requirements.
Mark Stephen, the chief customer officer for retail at Kiwibank, frames the problem plainly: when an unexpected bill arrives, when a car needs repair, when circumstances shift, savers lose their bonus rate through no fault of their own. "A single unexpected expense can mean the bonus disappears for the month, leaving savers earning a very low base rate instead," he said. The issue, he argues, isn't customer carelessness. It's that banks have designed products around the assumption that people will behave perfectly every month, and when they don't—when they actually need their savings—the structure punishes them. In an environment where household budgets are already stretched, this design choice has real consequences.
Kiwibank and BNZ are the only major banks that don't offer bonus accounts. Instead, they quote a single rate that customers actually receive, regardless of how often they access their money. Kiwibank's approach reflects a different philosophy: savings accounts should be simple, transparent, and deliver exactly what they promise. "The rate that's quoted is the rate that you earn, regardless of whether you are accessing those savings constantly," Stephen explained. It's a deliberate rejection of the bonus model.
David Cunningham, chief executive of Squirrel and formerly head of The Co-operative Bank, has watched this evolution over decades. When bonus accounts were first introduced roughly twenty-five years ago, interest rates sat around twelve to thirteen percent. Banks offered eleven percent as a base rate plus a 1.5 percent bonus for regular deposits—a genuine incentive to encourage disciplined saving. The logic made sense. Over time, though, the structure inverted. Banks began paying minimal base rates—near zero—and reserving meaningful returns only for customers who met strict conditions. "Over time, it became, 'Pay them bugger all, unless they do what they're required and that makes the bank make more money'," Cunningham said. The original purpose of encouraging saving had transformed into a mechanism that benefited the bank far more than the customer.
Data suggests the system works differently depending on account size. Cunningham's experience indicates that roughly half of customers in bonus accounts actually receive the bonus rate in any given month. But those customers hold about eighty percent of the total funds by value. Wealthier savers, more conscious of meeting deposit requirements and less likely to need emergency withdrawals, capture most of the advertised returns. Smaller savers, living closer to the edge of their budgets, lose the bonus more frequently and earn the punitive base rate instead.
ASB defends its structure as encouraging disciplined saving and rewarding customers who limit withdrawals. The bank notes that it has contacted more than 190,000 customers in the past year to suggest alternatives like term deposits or higher-interest options. But the underlying tension remains: a savings account is supposed to be accessible when needed, yet the product design penalizes access. The advertised rate and the actual rate a typical customer receives are often two different numbers, separated by conditions that ordinary life makes difficult to maintain.

Why do banks structure these accounts this way if it frustrates customers?
Because it works in the bank's favor. When half the customers miss the bonus in any given month, the bank pays out less interest than the headline rate suggests, while still being able to advertise that rate prominently.
But doesn't that damage trust?
In theory, yes. But most people don't track their actual returns closely enough to notice. And by the time they do, they've already chosen the account.
What about customers who need their money suddenly?
That's the design flaw. A savings account should be accessible—that's the whole point. But these accounts punish you for accessing them. You're caught between two needs: safety and return.
So Kiwibank's approach is just to offer a lower rate that's honest?
Exactly. They quote a rate and you get it. No conditions, no surprises. It's simpler, and it's fair, even if the number looks smaller on paper.
Do wealthier savers actually get the bonus more often?
Yes. If you have more money and fewer financial pressures, you're more likely to make regular deposits and avoid withdrawals. The system rewards stability, which wealthier people have more of.
Is this something regulators should look at?
That's the question now. When household budgets are tight and a single unexpected expense costs you eighty dollars in annual interest, the fairness of the design becomes harder to defend.
