Pandemics disproportionately affect vulnerable populations. Māori with serious mental illness who receive care through the public mental health system could have been the hardest affected in regard to COVID-19. Strategies created during COVID-19 entailed virtual methods to provide psychosocial support, in addition to broad public health campaigns that promoted public-facing materials to address emotional distress and promote wellbeing. There were policies to mitigate negative health and economic outcomes of COVID-19. Yet, there were few strategies focused upon people with serious mental illness, uniquely high risk, to minimise adverse outcomes from the pandemic. There is no evidence about the impact of COVID-19 upon Māori with pre-existing mental health issues, nor of the psychological impact of COVID-19 or the Government's public health precautionary measures on Māori. This study will be led by Māori Lived Experience Leaders to identify the impacts of COVID-19 on Māori.
