The New Zealand Government introduced a four-level alert system on 21 March to manage the COVID-19 pandemic in New Zealand. On 25 March, the country moved into Alert Level 4, placing the country in a nationwide lockdown and closing its borders. While mass gatherings were banned and schools and most businesses were closed, essential services such as supermarkets, petrol stations, and health services remained open. Due to successful efforts to eliminate the pandemic within New Zealand’s borders, the alert level system was progressively lowered to Level 3 on 27 April and Level 2 on 13 May, with lockdown restrictions and social distancing measures being eased at each stage.
