An analysis of 2015-2019 administrative data has found that enrolments in primary health organisations in New Zealand remain below full population coverage, with inequities between socio-demographic and geographic groups. In 2019, approximately 6% of the population were not enrolled. Enrolment rates were lower for Māori than for New Zealand European/Other groups, and people aged 15-24 years were the least likely to be enrolled. Enrolments were highest in the most affluent geographical areas, and were lowest for the Auckland District Health Board area.
