Trends in Working Age Population Percentage in New Zealand from 1990 to 2022

New Zealand’s working-age population remained relatively stable from 1990, starting at 65.7% and showing minimal fluctuation, peaking slightly at 66.5% in 2006-2007 before gradually declining to 65.0% in 2022. This stability reflects New Zealand's steady population growth, with moderate immigration balanced against an aging population. The slight decline from 2010 onward may be attributed to a maturing workforce and lower birth rates, factors that signal potential future challenges for labor force sustainability in the absence of significant immigration or policy interventions.
