Inflation in New Zealand
Consumer prices in New Zealand have risen 6,401.2% since Q1 1926, the start of the official series. That means NZ$100 then buys what NZ$6,501.22 buys in Q2 2026, so the same basket of goods now costs 65.0 times what it did. Over the most recent year on record, Q2 2025 to Q2 2026, prices rose 4.1%.

How inflation in New Zealand is measured
The figures above come from Stats NZ, republished by the OECD (CPI, all groups, quarterly). The series is indexed so that a chosen base year equals 100, and the calculator works out the ratio between any two dates you pick.
Coverage runs from Q1 1926 to Q2 2026, and updates automatically as each new release is published. New Zealand publishes CPI once a quarter rather than monthly, so dates here are given as quarters. Figures for the most recent periods can be revised by the statistics office after first publication.
