About this dataset
The consumers price index (CPI) measures the rate of price change of goods and services purchased by New Zealand households.
Purpose of collection
The aim of the CPI is to measure price changes of the same sample of products at each outlet over time. When there is a change in the size or quality of any of the goods or services in the basket, Stats NZ make an adjustment to ensure that the price change shown in the CPI is not affected by the change in size or quality.
The CPI is used to help set monetary policy and for monitoring economic performance. The government uses the CPI to adjust New Zealand Superannuation and unemployment benefit payments once a year, to help ensure that these payments maintain their purchasing power. Employers and employees use the CPI in wage negotiations.
Method of collection/Data provider
The CPI measures the rate of price change of goods and services purchased by New Zealand households. Stats NZ visits 2,800 shops around New Zealand to collect prices for the CPI and check product sizes and features.
