A flight carrying New Zealanders home from the Diamond Princess has landed at Whenuapai airbase.
The six were quarantined for two weeks on board the cruise ship after it had an outbreak of the Covid-19 virus.
They flew from Tokyo to Darwin on an Australian flight this morning, and then headed to Auckland on a 13-seat aircraft, with a St John ambulance officer and doctor on board.
Director-General of Health Ashley Bloomfield said they had shown no symptoms.
Two people were stopped from boarding the plane in Japan after they tested positive for the virus.
"They were all prepared to board the flight, it was just they had a positive test.
"I don't think they were heavily symptomatic, they hadn't presented with symptoms before they had the test," Dr Bloomfield said.
