Income - Average and median household income by type (for all households) 2007–2019
Income figures are collected for people aged 15 years and over.
Income is rounded to the nearest dollar.
Percentage changes are rounded to one decimal place and are calculated using unrounded income figures.
Each statistic from this survey is based on a sample and is subject to a sampling error. This sampling error is based on the average annual household income figure.
Sampling errors are rounded to one decimal place.
Figures may not sum to stated totals, due to rounding.
Household: is either one person who usually resides alone, or two or more people who usually reside together and share facilities (such as for eating or cooking) in a private dwelling. A household may contain one or more families, other people in addition to a family, or no families at all, such as unrelated people living together.
Total housing costs: consists of expenditure from the following sources: mortgage principal repayments, mortgage interest payments, mortgage application fees, rent payments, other payments associated with renting (for example bonds paid in the last 12 months), property rates payments (both regional and local government), and payments associated with building-related insurance.

Limitations of the data
Two types of error are possible in estimates based on a sample survey: sampling error and non-sampling error. The sample size for this survey is approximately 5,500 households, therefore the error for subnational estimates may be significant.
The target population for HES (Income) is the usually resident population of New Zealand living in private dwellings, aged 15 years and over. This population does not include:
- overseas visitors who are in New Zealand for less than 12 months
- people living in non-private dwellings such as hotels, motels, boarding houses, hostels, and homes for the elderly
- patients in hospitals, or residents of psychiatric or penal institutions
- members of the permanent armed forces in group living facilities; for example, barracks
- people living on offshore islands (excluding Waiheke Island)
- members of the non-New Zealand armed forces
- non-New Zealand diplomats and their families.

About this dataset
The household economic survey (HES) is an annual survey designed to measure the economic wellbeing of New Zealanders. HES has three components: HES income, HES expenditure, and HES net worth.
- HES income is the main vehicle, and it is run every year. It includes household income, housing costs, and material wellbeing – this is ‘core’ HES.
- HES expenditure includes additional components – an expenditure diary and an expanded household expenditure questionnaire. It runs every three years.
- HES net worth includes additional questions on household assets and liabilities. It also runs every three years.
Purpose of collection
The three main objectives of HES (Income) are to measure patterns of inequality in household income (used for policy-making decisions); measure people’s life satisfaction, housing conditions, and financial stress; provide an indication of the overall living standards of New Zealanders.
Method of collection/Data provider
For 2018/19 HES, Stats NZ increased the sample size to 28,500 dwellings for HES income (aiming to achieve 20,000 responses) and subsampled the required 5,500 dwellings for HES expenditure (aiming to achieve 3,500 responses).
