The key difference with the HLPIs is that it includes interest repayments, whereas the consumer price index (CPI) includes the cost of building a new home. The CPI measures how inflation affects New Zealand as a whole rather than household groups.
“Mortgage interest payments remain high, and continue to make a significant contribution to living costs for many households,” Stats NZ’s consumer prices manager James Mitchell said.
In contrast, the cost of building a new home increased 3% in the same period.
The cost of living for Maori households increased 5.5% in the 12 months to the June quarter, after a 6.3% rise in the March quarter.
Interest repayments (+26.4%), private transport supplies and services (+13.4%) and rent (+5.2%) were the largest contributors to higher costs.
The latest CPI data shows inflation is falling back towards the Reserve Bank’s target of 1-3%.
Inflation was 3.3% in the year to June 30, compared with a 4% rate in the 12 months to the March 2024 quarter.
