Written by Heidi Cuthbert Published Jul 21, 2026, 5:45 AM

New Zealand's consumer price index rose 4.1% in the 12 months to the June 2026 quarter.
Transport costs drove the surge, with higher petrol prices accounting for almost a quarter of the annual increase.
Broad price increases across key sectors pushed overall annual inflation past the Reserve Bank of New Zealand's target band.

New Zealand’s annual consumers' price index increased 4.1% in the 12 months to June, breaking past the central bank target.

The reading shows an acceleration from the 3.1% annual increase recorded in the previous March quarter.

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

Surging fuel prices played a central role, as petrol rose 27.5% and diesel jumped 71% over the 12-month period.

Excluding energy costs, the overall CPI rose 2.9% year-on-year, while quarterly inflation registered a 1.5% gain.

Additional pressure came from electricity prices climbing 12% and local authority rates advancing 8.8%.

More than 80% of the individual items tracked in the inflation basket saw price rises over the year.
