The breakfast show will be completely overhauled next month, with Lorraine Kelly and Aled Jones taking over from interim hosts Kate Garraway and Dan Lobb on September 3.
Daybreak has struggled in the ratings since it launched with Adrian Chiles and Christine Bleakley in 2010. It currently attracts around 700,000 viewers - half that of rival BBC Breakfast.
"Daybreak will have a new studio and a new on-air look," the Sunday Mirror quotes Fincham as saying.
"We're particularly excited about Lorraine and Aled joining as presenters.
"We have a very strong editorial team who are committed to making this show as good as it possibly can be, but it's something that doesn't happen overnight."
5 News presenter Matt Barbet and BBC North West Tonight co-anchor Ranvir Singh will also join Daybreak to host the first hour of the show from 6am each morning.
