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.
The seven-day rolling average of community case numbers is 7927 - last Tuesday it was 7943. Total number of publicly reported deaths with Covid-19 is now 876 and the seven-day rolling average is 14.
"Of the people whose deaths we are reporting today; one person was from Northland, two from Auckland, one from Waikato, one from MidCentral, one from Hawke's Bay, one from the Wellington region; six from Canterbury and one from Southern," the ministry said.
"Six were in their 70s; three in their 80s and five were aged over 90. Nine were women and five were men."
Yesterday another two cases of the BA-5 variant of Omicron had been identified in the country - both people arrived from overseas.
There were 6407 new cases of Covid-19 in the community.
The ministry reported a slight decrease in the seven-day rolling average of cases from last week, from 7553 to 7479.
Another two people had died in the previous 24 hours.
