It comes as the ministry reports another 9173 new cases and 14 deaths today.
This time last year, the total of cases reported in New Zealand was 2288, the ministry said.
"New Zealanders' collective response to Covid-19 helped us to keep our case numbers low, especially in that first year when the virus was rampant internationally," it said.
In its latest update today, the ministry said 385 people were in hospital with the virus - compared with 368 people in its previous update yesterday. There were 13 people in ICU.
