Discovery revealed in a statement at the time they planned to "reinvigorate" The AM Show - likely in an effort to better compete with TVNZ's Breakfast.
"Mel is an extraordinary journalist with experience as a news reader, reporter and foreign correspondent. Along with that credibility, she's also so much fun and a great conversationalist, which is a winning mix in the mornings," a statement from Newshub's director of news Sarah Bristow read.
"Since Ryan joined The AM Show, we have seen audiences respond with share growing in almost every demographic. They love what he is bringing to the mornings and together, Ryan and Mel will be an irresistible combo," Bristow added.
Chan-Green will continue to present Newshub Live at 6pm with Mike McRoberts until Samantha Hayes returns from maternity leave early in the new year.
She said she "couldn't wait" to join the show, and Bridge says in a statement he looks forward to hosting the newly-branded show with Chan-Green.
