The programme will screen in the timeslot that his chat show was destined for.
Henry told Spy he will tape some episodes before he leaves for Sydney and tape some more when he returns to Auckland briefly in February.
"It is an easier format for filming. It works better and requires less of me. We can shoot several episodes together over weekends in front of a live studio audience," he said.
Henry says it's full steam ahead for the Channel Ten breakfast show and Lachlan Murdoch has scheduled an on-air date for Monday, February 27.
"He wants me to be involved in employing the female co-host," Henry said, "so I'm keen for a late-February start to give me some time to do that."
Multi-million dollar injection for MediaWorks
Rumours circulated that MediaWorks would breach its banking governance in November, but the company's group managing director, Sussan Turner, happily told Spy this did not happen.
Instead, owners Ironbridge Capital - which bought the media company from CanWest in 2007 for about $790m - is set to plough "around $20 million" into the company across the radio and television divisions, according to an inside source. Turner would only say Ironbridge is "fully committed to the business".
"The fact Ironbridge is prepared to spend that sort of money on the company from its investment portfolios and piggy banks shows it's dedicated to growing it," the insider said. "Basically, it's an endorsement that they trust Sussan to deliver performances from the business."
Media commentators have long speculated the Australian private equity firm has wanted to sell the company, but it paid top dollar and would want the next buyer to do the same.
When the capital injection takes place, and I understand this will be in various chunks, it will make a significant impact. There would be big marketing dollars to spend on campaigns and money for operational costs. It's good news all round.
