New Zealand's Prime Minister Jacinda Ardern said that people working at the borders must be vaccinated by the end of this month or risk being moved out of the role, after a third coronavirus case related to a frontline staff was reported.

New Zealand has virtually eliminated the Covid-19 virus within its borders and there's been no community transmission for more 40 days. But it reported a positive Covid-19 in the community last week of a border worker who had missed two vaccine appointments.

Two more cases linked to this individual has emerged since, according to Reuters.

“By the end of April, those not yet vaccinated will not be permitted to work in high-risk workplaces and will be moved to other roles,” Ardern said at a news conference.
