The cost of living for the average New Zealand household rose 5.4% in the year to the June quarter, according to Statistics NZ.
These figures come from Statistics NZ's Household Living-costs Price Indexes (HLPIs). Unlike the Consumers Price Index (CPI), the HLPIs include interest payments.
Each quarter, the HLPIs track how inflation impacts 13 different household groups, as well as an all-households group, also known as the average household.
In contrast, the CPI measures inflation's effect on New Zealand as a whole.
“Mortgage interest payments remain high and continue to make a significant contribution to living costs for many households,” Statistics NZ consumer prices manager James Mitchell says.
Interest payments on debt jumped 26.7% in the June quarter. This figure has edged down slightly from the two previous quarters but is still very high.
Across the past two quarters, average interest payments were up 28% in the 12 months to March, and in the year to December 2023, average households faced a 31% increase.
Insurance costs were up 18% in June, from 17.9% in March. Private transport supplies and services rose 13% in the June quarter, a jump from 9.6% three months earlier.
The HLPIs annual increase of 5.4% for the year ending in June was down from 6.2% for the 12 months to March. However, this is still higher than the June quarter's annual CPI inflation rate of 3.3%.
Mitchell says this is the last quarter that will see the impact of council rates increases households experienced in the second half of 2023.
Property rates and related services make up 7.7% of expenditure for superannuitant households compared with 4.6% for the average household.
“On an annual basis, these rates increases are still a significant driver of inflation for superannuitant households,” Mitchell says.
The most recent high in average household living costs was the 8.2% rise recorded in the 12 months to the December 2022 quarter. The CPI peaked at 7.3% in the June 2022 quarter.
Stats NZ says that the CPI and HLPIs measures serve different purposes. The CPI is primarily used for monetary policy, while the HLPIs offer insights into the cost of living for various household groups.
