An employment lawyer says you can't fire someone for not wanting the Covid-19 vaccine. 

Prime Minister Jacinda Ardern says frontline border workers who haven't been vaccinated will need to start being moved into "low risk" roles from Monday.

Health officials say about 20 per cent of our border workers have not yet had their jabs.

Chris Scarrott told Heather du Plessis-Allan there's no case law on this yet in New Zealand, which makes things uncertain.

He says their view is you can't dismiss someone, and may need to look at moving them to other parts of the workforce.
