Introduction. New Zealand's health care system faces significant shortages in health care workers. To address workforce challenges and meet the population's health needs, health care systems around the world have introduced new clinical roles, such as physician associates/ assistants (PAs) into existing health care teams. Aim. This article aims to examine the benefits, challenges, and broader implications of regulating PAs in the context of New Zealand's primary care sector, with a specific emphasis on how it may impact general practice. Methods. A range of literature surrounding the role, impact, and perception of PAs were selected and included in this article. Results. The PA profession can significantly strengthen New Zealand's primary care workforce, improving patient access and continuity of care. However, the global deployment of PAs has faced scrutiny due to concerns about its potential risks to patient safety and the overall viability of such a role. Discussion. If regulated, the PA profession can reshape New Zealand's primary care, offering a partial solution to current medical staff shortages. Trained under a generalised medical model similar to doctors, PAs possess the necessary skills to perform both routine and non-routine medical tasks. This dual capability can significantly improve primary care service provision, reduce existing workloads, and allow for a more efficient deployment of doctor expertise. However, medico-legal issues and the supervisory burden can impede widespread integration into general practice. Despite challenges, the success of the PA role relies on mutual trust, respect, and support from other clinical team members within primary health care.
