Updated

The CPI index for petrol, quarterly from 1981. It tracks the change in pump prices households pay, including taxes and levies.

An index of price change, not a price per litre. Dollars-per-litre and the tax breakdown come from MBIE's weekly fuel monitoring (to be added via manual download).

An annual price change compares prices with the same period a year earlier. Each household buys a different mix of goods and services, so its own cost increase can differ from the national basket.

Read the period beside each number before comparing it with another figure. A monthly observation, a quarterly result and a financial year cover different spans of time. The latest release can also revise earlier observations. The chart and downloads keep the published periods so you can check which figures are being compared. A change in petrol describes what happened during that period; it does not by itself explain why it happened or identify the effect of a government policy. Definitions and coverage matter as much as the size of a change.

Petrol price index (quarterly) was 1,360.0 index in Jun 2025 qtr, a year earlier.

The earliest observation on the same basis was 279.7 index in Mar 1981 qtr.
