An observational study has found that the COVID-19 pandemic was associated with changed patterns of primary health care (PHC) enrolment in New Zealand. The study analysed enrolments at PHCs between 2016 and 2023, with Poisson regression models used to determine whether changes in enrolment were due to the COVID-19 pandemic. In 2016, enrolment was lower for Māori, young people and the most deprived compared with their peers. Enrolment rates decreased over time for Māori and Pacific people, as well as for those who were the most deprived. Enrolment rates increased for young people, those with the lowest levels of socioeconomic deprivation and those in the “other” ethnic category, mainly European New Zealanders.
