New Zealand Cricket are likely to have a solid pile of candidates for the job when it's advertised soon. There are no guarantees for Bradburn, who took ND to limited overs and first-class titles before heading overseas.
"I suspect there aren't many jobs in the world he would leave Scotland for, but that would be one and we would absolutely recognise that. We wouldn't stop him going for that job," Cannon said.
Scotland have beaten four full member nations and Bradburn, who played seven tests and 11 ODIs in the 1990s and early 2000s, has been a significant figure in their growing professionalism, Cannon added.
"Grant has professionalised the whole approach Scotland has to the men's game. Professional cricket has only existed nine years in Scotland.
"What he has done is put other parts of professionalism to the team in terms of approach, training, diet, strength and conditioning. But more than that he's brought a different attitude. He's taught the players to take responsibility."
Scotland have no games inked in yet for next year, making it a tricky selling exercise. But Scotland want Bradburn to stay.
"He's been a massive part of the team. He's done his hard yards and made major difference.
"It would be a step up but one I know he's capable of doing," Cannon added of the New Zealand vacancy.
