Public health researchers have proposed an expansion of the national COVID-19 alert level system. They note that several aspects of the current system have not worked adequately for Māori. The revised alert levels range from 0 through 6, with Levels 0-1 representing prepare (green), Levels 2-4 representing stop the spread (amber) and Levels 5-6 representing stay-at-home (red). Benefits of the revised system include: upholding Te Tiriti and implementing a more equitable response, better calibrating controls to the level of risk, responding to new knowledge, signalling improvements and innovation, supporting harmonisation with Australia (and the wider world), and establishing protective measures for a safer future.
