About the HLPIs and link to CPI
- Each quarter, the household living-costs price indexes (HLPIs) measure how inflation affects 13 different household groups, plus an all-households group. The consumers price index (CPI) measures how inflation affects New Zealand as a whole.
- The all-households group, or the average household, represents all private New Zealand-resident households. Lowest-spending, middle-spending, and highest-spending groups relate to expenditure quintiles 1, 3, and 5.
- has more information about the different household groups.
- Annual inflation, as measured by the CPI, was 2.2 percent in the September 2024 quarter , while annual inflation for the average household as measured by the HLPIs was 3.8 percent. The two measures of inflation are typically used for different purposes. A key use of the CPI is for monetary policy, while the HLPIs provide insight into the cost of living for different household groups.
- One important difference between the two is the treatment of housing. The CPI captures the cost of building a new home, while the HLPIs capture mortgage interest payments.
- has more information about how we measure different housing-related costs.
- In the HLPIs, interest payments increased by 18.2 percent for the average household in the 12 months to the September 2024 quarter. In the CPI, the cost of building a new home increased by 2.5 percent in the same period.
