There are 11 new cases of Covid-19 in managed isolation in New Zealand since the Ministry of Health's last update on 29 December.

There are no new cases in the community.

The new cases have come from across the globe: Canada, US, South Africa, Netherlands, India and the UK. The origin of one traveller is unknown.

From midnight tonight people returning to New Zealand from higher-risk countries including the UK and US will be required to undergo an additional Covid-19 test on Day 0 or Day 1 of returning to New Zealand.

The new border-protection moves have been prompted by the emergence of new and more contagious virus variants around the world, and ongoing high rates of the disease in some countries.
