Big Four Bank ANZ Raises Home Loan Rates as RBNZ Signals More OCR Hikes Ahead

New Zealand homeowners could face higher borrowing costs in the months ahead after ANZ increased most of its home loan rates, even as the Reserve Bank of New Zealand (RBNZ) chose to leave the Official Cash Rate unchanged.

The country’s largest retail bank raised most fixed mortgage rates by 20 basis points, signalling that lenders remain concerned about inflation and the possibility of further monetary tightening. While the central bank kept the OCR at 2.25% last week, policymakers made it clear that additional rate increases remain on the table if inflation does not return to target quickly enough.

ANZ’s updated home loan pricing now places its six-month fixed rate at 5.29%, while the one-year rate has increased by 10 basis points to 5.39%. The bank’s two-year rate now stands at 6.09%, and borrowers seeking longer-term certainty face a five-year fixed rate of 6.49%. ANZ’s floating home loan rate is currently 5.79%.

The timing of the move has drawn attention because many borrowers expected mortgage rates to remain stable following the RBNZ’s decision to hold the OCR. However, banks often adjust lending rates based on future expectations rather than current policy settings alone. Rising inflation forecasts, wholesale funding costs and expectations for future OCR changes all play a role in determining mortgage pricing.

During the latest monetary policy announcement, RBNZ Governor Anna Breman indicated that further OCR increases could still be required. She said policymakers would continue evaluating incoming economic data to determine whether weaker demand is sufficient to bring inflation back within the target range or whether higher interest rates will be needed.

Inflation remains one of the biggest concerns facing the central bank. Annual inflation was last recorded at 3.1%, slightly above the RBNZ’s target range of 1% to 3%. More significantly, central bank forecasts suggest inflation could rise to 4.3% in the September quarter before easing over time.

The outlook for inflation has become increasingly important for both borrowers and lenders. Recent analysis of the RBNZ OCR decision and inflation outlook highlighted how persistent price pressures could delay any meaningful decline in borrowing costs across New Zealand’s housing market.

In its policy statement, the Reserve Bank noted that future OCR decisions will depend on the balance between persistent wage growth, price-setting behaviour and signs of slowing economic activity. That message has reinforced market expectations that interest rates may stay elevated for longer than previously anticipated.

ANZ’s latest pricing also compares unfavourably with several competing offers from other major banks. Westpac’s one-year special home loan rate was listed at 4.79%, while its two-year special rate stood at 5.19%. BNZ offered a one-year featured home loan rate of 4.65% and a two-year rate of 5.19%. ASB’s one-year fixed rate was also 4.65%, with a two-year rate of 5.25% and a five-year rate of 5.89%.

For borrowers approaching the end of a fixed-term mortgage, those differences may be significant. Even a small variation in rates can result in thousands of dollars in additional interest payments over the life of a loan. As a result, homeowners may increasingly compare lenders and negotiate more aggressively before committing to a new mortgage term.

The Reserve Bank’s latest guidance, available through the Reserve Bank of New Zealand, suggests policymakers remain focused on returning inflation to target while maintaining economic stability. Until inflation shows clearer signs of easing, uncertainty around interest rates is likely to remain a key issue for households and property investors alike.

While ANZ’s decision does not guarantee that every major lender will immediately follow suit, it offers an early indication of how banks are positioning themselves for a potentially higher-rate environment. For New Zealand borrowers, the latest increase serves as a reminder that mortgage costs remain closely tied to the inflation outlook and future central bank policy decisions.
