Coronavirus: New Zealand PM says all arrivals must self-isolate

New Zealand's PM has said nearly everyone entering the country from midnight on Sunday must self-isolate to contain the spread of the coronavirus.

Jacinda Ardern said the new measure also included returning New Zealanders. The only exemption is for small Pacific islands with no confirmed virus cases.

"I make no apologies. This is an unprecedented time," Ms Ardern said, describing the new rules as the strictest in the world.

New Zealand has six confirmed cases.
