Tensions flared when the departing protesters lit fires on either side of the airport driveway, fuelled by tyres and fenceposts. The Kaitaia Fire Station sent one appliance to put out the fires.
Mr Popata said the fires were "signals". "It was to show the s*** we've been through. It's to remind people of the houses, the marae, the taonga that has been destroyed."
Mr Le Prou said the occupation had taken police by surprise. "Police were not aware that this was going to happen."
Far North Mayor John Carter said flights were expected to resume by this morning. He said airport operators Far North Holdings and Barrier Air had been supportive and patient during talks to settle the stand-off.
"When we heard that medical services had been curtailed, that was the final button," he said.
The cancelled flight had been scheduled to land at 8.30am with five doctors on board from Whangarei. Mr Popata said the occupiers had agreed to allow the medical specialists in but Barrier Air was unwilling to take the risk.
As Parliament passed the third reading of the Te Hiku bill yesterday, pressure was being brought to end the airport standoff. Former Mana MP and relative of the protesters, Hone Harawira, held a heated conversation with the occupiers, soon after the flight was cancelled.
