The series, which has been named Breakfast and will star The Project's Andrew Rochford and New Zealand broadcaster Paul Henry, was scheduled to launch in January 2012.
However, the start-date has been pushed back by two weeks to ensure that network executives can find a co-host.
Rochford joked to the Herald Sun that almost every woman in Australian media has auditioned for the job, adding: "I guess it just takes a very special person to sit between Paul and I."
He also said that it is "really important" to both of them that they "get it right" from the beginning.
Rochford and Henry will meet for the first time this weekend to discuss the programme.
Australia's Next Top Model host Sarah Murdoch was initially linked to Breakfast, with one source saying: "Her name is being thrown about, but she certainly hasn't been signed. Current thoughts have Sarah doing a couple of days here and there. It'll be a bit like on The Circle or The Project with a slate of revolving hosts. It keeps things fresh."
Rochford's The Project co-star Carrie Bickmore was later linked to the job after industry insiders revealed that Ten bosses are "keen" on her, but they also said that she has "a lot of things keeping her in Melbourne" rather than relocating to Sydney for Breakfast.
