Median annual household gross income in New Zealand

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.

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.
Disposable income: total income plus tax credits, less ACC levy, less tax payable.
Total housing costs: consists of expenditure from 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.

Household Income and Living Survey (HILS) replaced the Household Economic Survey (HES) from July 2024.
As with the Household Economic Survey for the year ended June 2020, 2021, and 2022, the pandemic has impacted Stats NZ’s ability to conduct face-to-face interviews in respondent’s homes and no other means of interviewing were available. Therefore, interviewing was not conducted evenly over the whole year. Consequently, the sample size was reduced to 8,900 households from the planned 20,000 households. The reduced sample size means margins of error on the statistics are higher than designed for.

The target population 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.

Household income and housing-cost statistics provide income and expenditure information for households, and demographic data on households and individuals in New Zealand.
The Household Income and Living Survey (HILS) was established to replace the Household Economic Survey (HES) from July 2024.

The primary objective of both HES and HILS is to facilitate the analysis and monitoring of the social and economic welfare of New Zealand. Social and economic welfare is measured through income, expenditure, housing costs, net worth, and non-monetary measures.
