Finance companies in New Zealand have lifted their residential mortgage lending by more than 30 percent in the nine months since the country’s first deposit guarantee took effect, the Reserve Bank says, in the clearest sign yet that the new scheme is doing exactly what it was designed to do.
The figures come from the central bank’s May 2026 Financial Stability Report, released this week. They show the Depositor Compensation Scheme, which became operational on 1 July 2025, has quietly redrawn the boundary between the four Australian-owned banks that dominate New Zealand banking and the much smaller pool of locally owned finance companies that have spent decades on the margins.
The scheme automatically insures up to 100,000 dollars per depositor at every licensed deposit taker, including registered banks, credit unions, building societies and finance companies. Before its launch, a saver chasing a higher term deposit rate at a finance company was effectively asked to take on more risk for the extra return. After 1 July 2025, that extra risk on the first 100,000 dollars vanished by law.
The Reserve Bank reports that deposits in finance companies have grown by more than 30 percent since the start of 2025, reaching roughly 700 million dollars by January 2026. That is a striking growth rate, even if the absolute number remains tiny. Finance company deposits still represent about 0.14 percent of the total deposit base across all licensed deposit takers in New Zealand. Mortgage lending by the same group has grown in lockstep, climbing from a smaller base to about 550 million dollars.
For context, registered banks hold approximately 388 billion dollars of New Zealand mortgage lending on their books. The finance company total, in other words, is around one seven-hundredth of the bank total. Even after a 30 percent jump, this is a corner of the lending market rather than a wing of it.
The mechanism behind the shift is straightforward. The Reserve Bank notes that “the spread between finance companies’ and banks’ term deposits has narrowed to around 0.5 percentage points, as eligible deposits in both types of deposit takers carry the same level of risk from the perspective of the depositor.” Translated, finance companies no longer need to dangle a fat risk premium to attract money. They can pay savers less than they used to and still pull deposits, then turn around and lend at rates that undercut the big four banks. The borrower wins, the saver does only modestly worse than before, and the finance company writes more business.
That is the textbook outcome regulators have always claimed deposit insurance would deliver. New Zealand was, until last year, the only OECD country without such a scheme. Whether the modest scale of the shift so far justifies the years of consultation, legislative drafting and levy debate is a separate question, but the early data lines up with the policy intent.
Risk is the obvious follow-up question. A 30 percent jump in mortgage lending at a category of lender historically associated with second-tier credit, motor vehicle finance and consumer loans would normally have prudential supervisors paying close attention. The Reserve Bank’s verdict is reassuring on the numbers it can see. Roughly 80 percent of finance company mortgages have loan-to-value ratios below 70 percent at origination, the report says, and non-performing loan rates remain low. The growth is starting from a very small base.
The central bank’s overall conclusion is that “the overall level of lending through finance companies remains low when compared to overall lending in the system” and that financial stability risks from the trend are “likely to be limited.” That is supervisor language for, we are watching it but we are not worried yet.
Reserve Bank Governor Anna Breman framed the wider report in similarly steady terms. She said New Zealand’s financial system “is resilient and well positioned to support households and businesses even if economic conditions soften,” while warning that “the global risk environment has worsened over the past six months, as conflict in the Middle East threatens world energy supply.” The finance company chapter is one of the rare bright spots in a report otherwise dominated by warnings about insurance affordability, climate-driven repricing of catastrophe cover, and the pressure higher fuel costs are putting on household budgets and small business margins.
The practical takeaway for ordinary New Zealanders sits on both sides of the bank counter. Savers comparing term deposit rates can now treat finance company offers and bank offers as carrying the same default risk on the first 100,000 dollars, which makes the comparison genuinely about rate rather than rate plus a hard-to-price chance of losing the lot. Borrowers, particularly those whose loan files do not fit the cookie cutter of a registered bank, are starting to see a small but visibly growing pool of alternative lenders willing to write the loan at a competitive rate.
None of this is going to dent the four Australian-owned banks’ near monopoly on New Zealand mortgages any time soon. As interest.co.nz notes in its coverage, the math is simply too lopsided. But for the first time in a generation, the trend line on competition in deposit taking is pointing the right way, and the policy lever the Reserve Bank pulled in July 2025 is the reason.
What do you think — would you move money to a smaller finance company now that the first 100,000 dollars is government-guaranteed, or does the brand recognition of a big four bank still win out? Have your say in the comments.
