Employed: people in the working-age population who, during the reference week, did one of the following:
- worked for one hour or more for pay or profit in the context of an employee/employer relationship or self-employment
- worked without pay for one hour or more in work which contributed directly to the operation of a farm, business, or professional practice owned or operated by a relative
- had a job but were not at work due to: own illness or injury, personal or family responsibilities, bad weather or mechanical breakdown, direct involvement in an industrial dispute, or leave or holiday.

Working-age population: the usually resident, non-institutionalised, civilian population of New Zealand aged 15 years and over. This is the target population for this survey.

Labour force: members of the working-age population, who during the survey reference week, were classified as 'employed' or 'unemployed’.
Potential labour force: people who are not actively seeking but are available and wanting a job, and people who are actively seeking but not currently available for work, but will be available in the next four weeks.
Extended labour force: people in the labour force, or in the potential labour force.

Underemployed: people who are in part-time employment who would like to, and are available to, work more hours.
Unemployed: all people in the working-age population who, during the reference week, were without a paid job, available for work, and had either actively sought work in the past four weeks ending with the reference week, or had a new job to start within the next four weeks.

Underutilised: the sum of those unemployed, underemployed, and in the potential labour force.

The primary purpose of the survey is to estimate the number of people employed, unemployed, and not in the labour force (NILF), and from them, the unemployment rate for the New Zealand labour market. The Household Labour Force Survey (HLFS) is designed to produce statistics at the family level, and use of the survey for a purpose for which it was not designed is inevitably subject to some limitations.
