Stats NZ: New Zealand's official statistics

Stats NZ (Tatauranga Aotearoa) is New Zealand's national statistics office. It runs the census and publishes the quarterly CPI, monthly selected price indexes, labour market statistics, GDP, population estimates, international migration and births and deaths. Each information release has key facts, a next-release date and downloadable data. Fact-checkers use it for most claims about New Zealand's economy and population.

When it publishes

Stats NZ releases are published at 10:45 am New Zealand time on dates set in its release calendar, and each release states when the next one is due.

How to use it to check a claim

1. Check whether a figure is seasonally adjusted and whether it is quarterly or annual change.
2. For migration, use the latest release, as provisional figures are revised.
3. For earnings, say whether the figure is a median (income release) or a mean (QES).

Common mistakes

• The monthly selected price indexes are not the full CPI.
• Census counts and population estimates differ by design.
• Stats NZ pages load content with scripts, so some automated tools see a blank page.

When is the next CPI?

Stats NZ says the September 2026 quarter CPI will be released on 22 October 2026.
