Live: Does the Govt need to introduce a level 4.5?
A top Covid expert says if the virus spreads further amongst essential workers then the government will need to introduce a level four point five, including having all such workers vaccinated.
Of the 511 cases confirmed so far as part of the latest outbreak, 73 are essential workers.
Epidemiologist Rod Jackson told RNZ's Nine to Noon, that with the rest of the country in lockdown, these workers, who were the only group allowed to move about in the community, were one of the main ways for the virus to spread.
He says essential workers could also be required to wear masks all of the time.
Meanwhile, Cabinet ministers are deciding the next steps for Auckland and Northland and will announce their decision at 4pm today.
The rest of the country is set to move to alert level 3 from midnight tomorrow.
