The Reserve Bank has held rates, but banks are raising mortgage rates? Is New Zealand's housing market entering its toughest phase?

As banks begin raising mortgage rates while house prices remain flat, buyers, sellers, developers and investors are all waiting for the next card to be played. The question is, can the market still follow its familiar script this time?

For many New Zealand households, the past few years have cemented an almost unshakeable understanding: when the Reserve Bank cuts rates, mortgage rates fall and the property market recovers; when it raises rates, house prices come under pressure and sales cool.

Yet since the start of 2026, an increasingly puzzling pattern has emerged: the official cash rate (OCR) has not risen, but mortgage rates have already moved higher. Borrowing costs are increasing, while house prices have shown little change.

This situation is making homebuyers hesitate and drawing sellers, developers and even banks themselves into a delicate strategic contest. New Zealand's property market is entering its most difficult phase to read in recent years.

The Reserve Bank of New Zealand holds steady, but banks move first to raise rates

The Reserve Bank of New Zealand (RBNZ) recently decided to leave the OCR unchanged at 2.25%.

On the surface, this appears to suggest a temporarily stable interest rate environment. However, the market's focus is less on the Reserve Bank's lack of action than on the signals it is sending.

Reserve Bank of New Zealand Governor Anna Breman said further OCR increases this year could not be ruled out if inflation pressures did not ease materially over the coming months. The bank's latest forecasts even suggest inflation could climb back to 4.3% in the third quarter of this year, well above its target range of 1% to 3%.

The market reacted swiftly.

ANZ, New Zealand's largest mortgage lender, was first to announce increases to most of its fixed mortgage rates, with its two-year fixed rate back above 6%.

The move immediately attracted market attention. Its timing suggests this was not an increase directly driven by the OCR, but rather a bank preparing in advance for a possible future rise in the OCR.

For many households considering locking in a rate, a reality is already confronting them: the cycle of falling interest rates has ended, and a new upward cycle may be beginning.

Mortgage rates have risen, but house prices have not followed

Many buyers might be able to accept rising mortgage rates if house prices were also increasing. But the current market's awkward reality is precisely that borrowing costs are rising while house prices are barely moving.

If there is one word to describe New Zealand's housing market today, 'pause' may be more fitting than 'recovery'.

Cotality data shows national house prices were virtually unchanged in May. Over the past year, prices nationwide still slipped 0.6%, and overall prices remain around 17% below the market peak in early 2022.

The market has neither delivered the strong rebound many hoped for nor returned to its earlier downward trajectory. After more than three years of adjustment, housing appears to have entered a relatively quiet period. But whether this calm is laying the groundwork for another rise or simply forms part of a prolonged consolidation remains a question no one can yet answer definitively.

Regional differences remain pronounced.

Southland, the West Coast and parts of Canterbury continue to record modest growth, while major cities such as Auckland and Wellington remain weak.

These differences reflect an uneven economic recovery across New Zealand. Some regions linked to agriculture and exports remain resilient, while urban economies dependent on consumer spending and services face greater pressure. Their property markets naturally show sharply different results.

Buyers are waiting, and so are sellers

Perhaps the most noteworthy aspect of New Zealand's housing market today is not house prices themselves, but changing attitudes among buyers and sellers.

Over the past few years, the market has experienced both frenzied competition for homes and a rapid cooling. Now, however, neither buyers nor sellers seem particularly motivated to make the first move.

For buyers, listings remain plentiful and there is plenty of choice. Even when they find a property they like, they are often willing to watch for a while longer in the hope of securing a better price and terms. High stock levels give them greater bargaining power, so they feel little urgency to decide.

Meanwhile, sellers are not as pessimistic as might be expected. Although economic growth has slowed and the labour market has cooled, relatively few people are genuinely being forced to sell because of financial pressure. For many owners, holding on and waiting for the market to improve is preferable to accepting an offer below expectations.

When buyers are unwilling to bid higher and sellers are unwilling to lower their prices, the market naturally enters a period of sideways consolidation.

This also explains why neither sales volumes nor house prices have shown a clear direction over recent months.

The property market resembles a long poker game, with everyone waiting for someone else to show their hand first.

Why are banks raising rates?

Perhaps a more intriguing question than the direction of house prices is:

Why are banks raising mortgage rates now?

Interest.co.nz columnist David Chaston has offered a perspective worth considering.

Recent movements in wholesale interest rates, or swap rates, show no obvious change substantial enough to justify a sharp rise in mortgage rates.

In other words, ANZ's latest rate increases cannot be explained entirely by rising funding costs.

David Chaston believes a more plausible explanation may lie elsewhere: bank profit margins.

Over the past few years, major banks repeatedly lowered mortgage rates to compete for market share, squeezing their lending margins. Now, as markets once again expect further OCR increases, banks are gaining more room to restore profitability.

Put simply, this may be more than an adjustment in interest rates; it may also be an effort to rebuild bank profitability.

For borrowers, this means the pace of future mortgage cost increases may not depend entirely on the Reserve Bank. Banks' own commercial strategies could also become an important variable.

Pressure is building again in construction

Meanwhile, property developers are also facing new challenges.

Data shows that, in the year to April this year, residential building consents nationwide had recovered to around 39,100 homes. Annual totals had exceeded year-earlier levels for nine consecutive months, reaching their highest level since October 2023.

The figures are undoubtedly a positive signal, but new pressures are emerging beneath the headline growth.

Rising building material prices, higher transport surcharges and financing costs, together with persistently flat house prices, are steadily squeezing developers' margins.

For developers, the biggest challenge is that costs keep rising while they lack the ability to lift sale prices accordingly.

If this situation continues, building consent figures in the second half of this year may struggle to maintain their current growth momentum.

This is, in fact, an easily overlooked contradiction in today's market: housing supply is recovering, but development profits have not improved alongside it. If financing conditions tighten further, developers' willingness to invest in future projects could well be affected again.

Will Australian investors become the 'saviours' of New Zealand's housing market?

Another recent talking point has been Australia's discussions about reforming capital gains tax (CGT) and negative gearing policies.

Many market participants have begun wondering whether this could prompt large numbers of Australian investors to turn to New Zealand property.

On the surface, New Zealand does offer some attractions: no comprehensive capital gains tax, house prices well below their peak, and a relatively favourable exchange rate.

But the reality may be more complicated than it appears.

Even if investors hold New Zealand properties beyond the bright-line period, they may still face capital gains tax obligations under Australia's tax system.

More importantly, New Zealand will hold a general election at the end of this year. Both capital gains tax discussions and mortgage interest deductibility could return to the spotlight as the political landscape changes.

For serious property investors, rental returns, market liquidity and long-term growth potential often matter more than tax advantages alone.

It therefore seems premature to expect a large influx of Australian capital to drive up house prices.

Observations and reflections

Over the past few years, falling interest rates have been the biggest driving force in New Zealand's property market.

That is now changing. Mortgage rates are beginning to rise again, but house prices are not rising alongside them. Buyers continue to wait, sellers hold firm on price, and developers face pressure from rising costs.

The market may look calm on the surface, but that calm resembles a stalemate. Buyers are waiting for a better time, sellers are waiting for a recovery, and banks have already begun preparing for a higher interest rate environment.

If mortgage rates keep rising while house prices remain flat, New Zealand's property market may have to adapt to a new reality: its momentum will come from real income growth, demographic changes and economic fundamentals rather than ever-falling interest rates. Such a market may be harder to predict than it has been over the past few years.
