If you are one of the tens of thousands of New Zealanders travelling overseas, you should prepare to stay put and seek shelter, says Foreign Minister Winston Peters.
The window for flying home is almost completely closed.
Many countries, like Singapore, are now preventing travellers in transit to try contain the spread of Covid-19, Peters said.
But if you are able to get a flight, you should do it immediately as mercy flights can't be guaranteed.
"We are reaching a point where the best option for most New Zealanders offshore is to shelter in place, by preparing to safely stay where they are."
