Price indexes
Price indexes measure the change in price for a fixed ‘basket’ of goods and services between two time periods. This change is often called inflation.
Data from the food price index (FPI), the rental price indexes (RPI) and additional series are now available in the monthly release called selected price indexes (SPI) .
Introducing a new price index release has more information about what the SPI is and the data available in the release.
We collect prices to produce price indexes for several economic sectors.
Business price indexes include the producer's price index (PPI), capital goods price index (CGPI), and farm expenses price index (FEPI).
Consumers price index (CPI) measures the changing price of the goods and services New Zealand households buy. It provides a measure of inflation.
Food price index (FPI) measures the changes in prices that households pay for food and food services. We measure the price change by tracking the prices of individual food items that make up a representative food basket.
Household living-costs price indexes provide information on the rate of price change for goods and services purchased by select household groups, giving a measure of inflation for sub-sections of the population.
Labour market statistics provide a picture of the New Zealand labour market. They include the labour cost index, which measures changes in wages and salaries.
Overseas trade indexes (prices and volumes) measure changes in the levels of prices and volumes of merchandise imports and exports between New Zealand and the rest of the world.
Rental prices indexes measure the changes in prices that households pay for housing rentals.
Selected price indexes provides monthly price changes for a selection of goods and services that New Zealand households purchase.
