COVID-19 alert levels in New Zealand

A four-tier alert level restrictions system was in place in during the COVID-19 pandemic in New Zealand between March 2020 and December 2021, with levels 3 and 4 being forms of lockdown. In level 1 there were no restrictions; in level 2 there were limits on gatherings; in level 3 only purposeful travel was allowed and there were strict limits on gatherings; and in level 4 only essential travel was allowed and gatherings were banned.

The alert level system was replaced with the COVID-19 Protection Framework, known as the "traffic light" system, which uses vaccination rates to determine the level of restrictions needed. The traffic light system began 11:59 pm on 2 December 2021.

The country may return to the alert level system if a future major outbreak occurred that necessitated it, such as a new vaccine-resistant variant of SARS-CoV-2 (the virus that causes COVID-19).
