Abstract
The emergence of COVID-19 as a global pandemic in 2020 provided immense challenges to Public Health Units (PHUs) across New Zealand. PHUs were tasked with identifying COVID-19 cases, tracing their contacts, and managing quarantine and isolation for those with COVID-19. This qualitative case study aimed to investigate the delivery of public health services in the high intensity COVID-19 pandemic situation in the Nelson Marlborough District Health Board (NMDHB) to identify good practice and areas for possible future improvement.
