History of the COVID-19 Protection Framework (traffic lights)
About the traffic lights
The COVID-19 Protection Framework replaced Alert Levels in December 2021 and ended in mid-September 2022. It had 3 traffic light settings of Red, Orange and Green.
The framework aimed to:
- help people protect one another from the virus
- keep hospitalisation rates as low as possible and avoid overwhelming the health system
- minimise the impact of large outbreaks
- reduce the need for lockdowns.
It also aimed to give people and businesses more stability.
At all traffic light settings, essential services continued to operate. This included supermarkets, health services, emergency services, goods transport, and utilities such as power and water supplies.
Components of the framework
A high vaccination rate remains a key tool to protect people and minimise the spread of COVID-19. Getting vaccinated means you are less likely to get extremely sick or infect other people.
Some workplaces may require staff to be vaccinated. Vaccine mandates for government workers ended during 2022.
Wearing face masks remains a way to protect ourselves and others. At Red and Orange traffic light settings, there were some places people had to wear face masks, such as on public transport and in supermarkets.
At Red, capacity limits applied in some indoor settings. Limits were based on 1-metre distancing, which meant 1 metre square of space for each person, up to the maximum capacity limit. It did not mean everyone had to stay 1 metre apart.
Capacity limits did not include workers (paid and unpaid).
Local protections and lockdowns
If an area had very high infection rates, extra restrictions such as local lockdowns or other protective steps may have been used.
Examples of protective steps included:
- stay at home orders
- closing premises, such as schools or shops
- limiting numbers allowed at gatherings.

The Government introduces Omicron phases, with different approaches to testing and isolation as case numbers grow.
- Phase 1: Focus on stamping out small outbreaks, with PCR testing and 14-day isolation period for COVID-19 cases.
