This release incorporates revisions to historical household labour force survey data to account for the latest national population estimates. As such, figures published in this update may differ from those previously published.

At URL provided, select 'Work income and spending > Household Labour Force Survey - HLF > Persons employed in the labour force, by job tenure by sex by age group (Qrtly-Mar/Jun/Sep/Dec)'. All variables were selected to create this dataset.

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.
