New Zealand’s inflation problem remains stubbornly entrenched, with the latest figures showing price pressures still sitting above the ideal range and continuing to hit households where it hurts most.
According to Stats NZ, inflation held at 3.1% in the year to March 2026—still outside the Reserve Bank of New Zealand’s target band of one to three percent.
Electricity prices surged 12.5% over the year, making them the single biggest driver of inflation.
Stats NZ prices and deflators spokesperson Nicola Growden said electricity alone accounted for more than a tenth of the 3.1% rise in the Consumer Price Index, marking the third consecutive quarter it has been the largest upward pressure.
At the same time, global instability is adding further pressure. Concerns about inflation have been intensified by the Iran war and its impact on fuel costs. However, the latest data only captures the very beginning of the US and Israel’s war on Iran, meaning the full effect of rising fuel prices has yet to be felt.
On a quarterly basis, the CPI rose 0.9% in the March 2026 quarter, again highlighting persistent inflationary pressure. Petrol prices, up 3.5%, were the largest contributor. Growden noted that petrol remains the third-largest household expense in New Zealand, behind rent and construction.
Households were also hit by a sharp 17.7% rise in pharmaceutical prices during the quarter, driven by higher prescription charges. Stats NZ said this followed the reset of the prescription subsidy scheme on February 1, which meant households that had previously exceeded the 20-prescription threshold and received free prescriptions were once again required to pay the co-payment.
Petrol and pharmaceutical costs together made up more than a quarter of the quarterly CPI increase; other contributors included confectionery, nuts and snacks, fruit, and electricity.
