Consumers price index
The consumers price index (CPI) measures the changing price of the goods and services New Zealand households buy. It provides a measure of inflation.
To calculate CPI we select a fixed 'basket' of goods and services. We choose the items and determine their relative importance based on spending patterns. The items in the CPI basket represent how New Zealand households spend their money.
We collect the prices of the goods and services in the basket over time to measure how they change.
You can find out about price changes for 11 CPI groups:
- food
- housing and household utilities
- health
- recreation and culture
- education
- communication
- clothing and footwear
- transport
- alcoholic beverages and tobacco
- household contents and services
- miscellaneous goods and services.
