There are more than 350 people in hospital with Covid-19 and nine more deaths, the Ministry of Health has reported today. 

The ministry said there are 4402 new community cases of Covid-19 in New Zealand. 

Of the 354 people in hospital with the virus, eight are in intensive care. 

Today's numbers come ahead of a possible review of the country's traffic light pandemic response settings as the country continues to grapple with the Omicron variant.

In a press conference on Wednesday, he said waves of Omicron were still reverberating worldwide. 

Asked if New Zealand was still at the peak of the outbreak, Town said the country was instead on a "steady plateau". 

It was still unclear which of the current Omicron variants was most likely to cause severe illness. 

More than one million New Zealanders have contracted Covid-19. 

Yesterday, the country recorded 5202 new community cases, 332 hospitalisations, and eight deaths of people with Covid-19. 

The vast majority of new community cases were diagnosed by rapid antigen tests. 

Overseas, some experts have said exposure to Covid-19, through vaccination or infection, did not guarantee immunity from future infections.
