Rising interest rates change the equation for property buyers

Property buyers and investors may need to revisit their budgets after the Reserve Bank of New Zealand increased the official cash rate (OCR) for the second consecutive meeting.

The RBNZ lifted the OCR by 0.25 percentage points in both July and September, taking it from 2.25% to 2.75%. It has also left the door open to further increases as it works to return inflation sustainably to its 2% target.

For buyers, higher interest rates can affect both how much they can borrow and how much they would need to repay. That means someone who had their borrowing capacity assessed several months ago may find the numbers have changed.

Investors face similar considerations. Higher borrowing costs can affect cash flow and the financial viability of a potential purchase, making it important to run the numbers using current rates rather than relying on previous assumptions.

Mortgage rates have already been moving

The effect of an OCR increase is not necessarily immediate. Many borrowers have fixed-rate mortgages, so higher rates may affect them only when their existing term expires.

Realestate.co.nz CEO Sarah Wood said the July and September increases would therefore take time to work their way through the system. She also suggested some buyers and sellers may think twice about transacting in the current environment.

At the same time, mortgage rates do not simply move in lockstep with the OCR. The market had been anticipating higher interest rates before the RBNZ started raising the OCR, which meant fixed mortgage rates had already been increasing during 2026.

For anyone planning a property purchase, the changing rate environment makes it particularly important to understand your borrowing capacity and potential repayments before making an offer.
