One year on from the first time New Zealand entered alert level 4, RNZ takes a day-by-day look back at the unfolding of the pandemic in this country.
Thursday marks one year since New Zealand first moved to alert level 4, after cases of Covid-19 in the community kept climbing as people returned from overseas.
While a historic case was later classified as New Zealand's first Covid case - as they had reported having symptoms on arrival on 21 February - the first case of Covid-19 in New Zealand was reported on 28 February 2020. One year later and the country is still dealing with its effects.
The coronavirus first appeared in China in late 2019, just a few short months before it made its way to New Zealand. The new type of coronavirus is identified and isolated by Chinese authorities on 7 January, as the virus quickly spread into Thailand, Japan, South Korea, Taiwan, Hong Kong, Macau, and the United States.
By late January, 2020 the global number of cases rose to nearly 2800 and the death toll reached 80. In early February, 2020 New Zealand brought in entry restrictions on foreign nationals travelling here from, or transiting through, mainland China. But as cases in Wuhan started to decline, the virus started to explode worldwide, hitting Iran, South Korea and Italy hard, and New Zealand was not immune.
As at 24 March, 2021 New Zealand has recorded 2468 probable and confirmed cases and 26 deaths. There are 68 active cases.
28 February: New Zealand reports its first case of Covid-19, in a person in their 60s who has travelled to Auckland from Iran. The government places restrictions on people arriving from Iran.

Cruise ships are banned from the country. Strict border measures for people travelling from New Zealand to the Pacific are put in place.
15 March: Two more people test positive for the virus in New Zealand. Finance Minister Grant Robertson says the government is expecting a serious blow to the economy from the effects of the virus and the travel ban. France and Spain go into lockdown.

19 March: Eight further cases are announced, bringing the total number in New Zealand to 28. The new cases are in Southland, Taranaki, Rotorua, Northland, and Auckland. Director-General of Health Dr Ashley Bloomfield says all cases are linked to overseas travel, meaning the coronavirus has not yet been transmitted in the community.

She asks people who can work from home to do so, and says people should limit travel within the country. The government introduces a four-level alert system to help combat Covid-19. Ardern says the country is currently at level two, which means the risk of community transmission is growing.

Ardern says one of the community cases was possibly unknowingly infectious for as long as a week without isolation and had visited high risk locations, including a supermarket, a gym, and the Manukau Institute of Technology. "We may well have close contacts who are already infected," Ardern says. The latest cases could not be directly linked to earlier cases in the South Auckland cluster. One is a 21-year-old sibling of a Papatoetoe High School student and another the mother of the student, who had tested negative. Aucklanders are asked to wear masks when they leave their house. There is also one new case in managed isolation.
28 February: One year after the first case of Covid-19 is announced, Auckland goes into lockdown. One further community case is announced, but they were infectious while in quarantine so were not considered a risk to the public.
