Newstalk ZB nighttime host Marcus Lush will be taking a tilt at the Invercargill Mayor.

Lush will face off against eight other contenders and the long serving Sir Tim Shadbolt who has been in charge since 1998.

He won't be hanging up his microphone though he says he'll keep his hosting job on his top rating radio show.

Marcus Lush joined Heather du Plessis Allan Drive to discuss his upcoming mayoralty race.
