More information

COVID-19 Alert System

The Alert Level tables have not yet been updated to include information about wearing masks and movement between borders.

The Alert System was introduced in March 2020 to manage and minimise the risk of COVID-19 in New Zealand. The system helps people understand the current level of risk and the restrictions that must be followed. 

The measures may be updated on the basis of:

  • new scientific knowledge about COVID-19, and
  • information about the effectiveness of intervention measures in New Zealand and elsewhere.

The Alert Levels may be applied at a town, city, territorial local authority, regional or national level.

What all Alert Levels have in common

At all levels, essential services including health services, emergency services, utilities and goods transport will remain up and running. Employers in those sectors must continue to meet their health and safety obligations.

At all levels, if there is another emergency, follow normal emergency procedures. Emergency evacuation orders will override COVID-19 Alert System requirements to stay at home.
