Annual inflation rose to 4.1% in the June quarter, driven largely by a sharp increase in fuel prices rather than broad-based consumer demand.

Stats NZ said petrol prices rose 27.5% over the year and were the “largest upwards contributor” to the increase.

“Higher petrol prices accounted for almost a quarter of the 4.1% annual increase,” Stats NZ prices and deflators spokesperson Nicola Growden said.

Diesel prices rose even more sharply, increasing 71% and accounting for a further 7.7% of annual inflation. Together, petrol and diesel contributed roughly one-third of the headline figure.

That suggests much of the increase came from fuel costs, which are heavily influenced by international oil markets and exchange rates, rather than excessive household spending within New Zealand.

Inflation had been running at 3.1% in both the December 2025 and March 2026 quarters, after reaching 3% in September 2025.

Earlier increases were also concentrated in essential or unavoidable household costs. Electricity prices rose 12.5% in the year to March, while council rates increased 8.8% and meat and poultry prices rose 8.6%.

The latest result puts inflation well above the Reserve Bank’s 1% to 3% target range. However, higher interest rates cannot directly reduce the international price of petrol or diesel.

The Reserve Bank has already increased the Official Cash Rate to 2.5%, raising the possibility that mortgage holders and businesses could face higher borrowing costs in response to an inflation increase largely driven by imported fuel.
