About the HAM data
Introduced in May 2017, the Housing Affordability Measure (HAM) is an experimental statistical series that measures household income after paying for housing costs for 2 subsets of the population: potential first home buyers population and renters.
How affordability is calculated
Affordability is calculated by using data from Statistics New Zealand’s Integrated Data Infrastructure to measure income at the household level.
Housing costs – the rent lodged on tenancy bond forms for renters and mortgage payments, rates and insurance for potential first home buyers – are then subtracted. The remaining household income is then adjusted to reflect the fact that larger households generally need larger incomes.
