Denyer has quit the Seven game show just 10 weeks into the show’s run, citing family reasons.
“This has been a difficult decision because I love the show, but it’s in the best interests of my family at this time and as much as I love working on the show, I know it’s the right decision,” he said.
“The production schedule is gruelling and takes me away from home for extended periods of time.
“I’m pleased that I can pass the baton to Simon, who’s a good friend as well as a former colleague at Sunrise. I am a great admirer of Simon’s work and I know he’ll do a great job.”
But the move follows a lukewarm reception to Denyer as host as the show while it fought off ratings from Nine’s Hot Seat. A recent reader poll indicated some viewers could not warm to him as a quizmaster, with some feedback citing a lack of gravitas.
It’s also not the first time Denyer has quit a Seven television show. In March he quit Sunrise for family reasons.
The Million Dollar Minute announcement also comes on its final day of the TV ratings year, likely to fuel further speculation about behind the scenes motives.
Reeve will take over the hosting duties in the New Year.
