Corin Dann moved into broadcasting after studying politics at university, and journalism at Christchurch's New Zealand Broadcasting School. Starting as a sport intern at RNZ, he quickly moved into news. A tip from a friend landed him a job at Newstalk ZB, giving him his first taste of the Parliamentary Press Gallery. In 2007 he joined TVNZ to host its breakfast business show, before co-hosting Breakfast each weekday morning from late 2010. He became the channel’s Political Editor in 2012. In early 2018 it was announced that he'd be stepping down from the role, to work full time as host of weekend politics programme Q+A.

I was accepted into two different courses; one was for journalism and one was for radio production and DJing and that sort of stuff. I mustn’t have been entirely sure, but I ended up doing the journalism one. At that point I remember working out what the press gallery was all about, and from pretty early on deciding that was where I wanted to get to.
