The former Bass Brewers marketing director hopes to use his position to protect businesses' right to advertise.
He said: "Companies face a challenge in protecting their freedom to advertise from increasing regulation, especially during the current commercial downturn.
"One of my priorities as ISBA president will be to demonstrate to government how advertisers can be part of the solution to drive positive consumer choices in society."
Part of Hunter's role will be to chair the ISBA council, the organisation's senior governance body. He succeeds John Clare, the former chief executive of retailer DSG International.
