"I don't think any ratepayer in Northland would not support that," he said.
"We must keep this service, and expand it. We have to encourage Air New Zealand [which abandoned its service earlier this year], through the government, to recognise its obligation."
Mr Samuels said he had been in Cabinet when the then Labour government bailed out Air New Zealand in 2002 (to the tune of $885 million, which gave the government an 82 per cent shareholding; that has since reduced to 53 per cent). Meanwhile Northland deserved more than platitudes from the current government.
"This is crunch time. The government has to put up or shut up. Tell us the truth," he said.
"[Northland MP] Winston [Peters] is making the right noises but he's in opposition. The government will isolate him as much as it can, and we have to give him major support.
"If he and [former Labour MP] Shane Jones head the next New Zealand First campaign [Mr Peters] will be a major player in the next government, and will be in a position to deliver for Northland."
