What's happening to prices month by month?
The CPI comes out every three months. Stats NZ also prices food, rent, fuel and a few other things every month, so they show what's happening sooner.
These monthly figures run to Sep 2026, the same as the latest CPI (Sep 2026 quarter). The next monthly release will be newer than the CPI.

About these numbers
Selected price indexes are the parts of the CPI that Stats NZ prices every month. They use the same methods as the CPI.
Average prices are what an item cost on average across the shops Stats NZ surveys. Pack sizes and brands vary, so compare an item with itself over time rather than with other items.
Rents for new tenancies ("flow") show what new renters pay; all tenancies ("stock") includes people already renting, so it moves more slowly.
