Comedian Rove McManus has lost his spot on NBC's popular Tonight Show.

The long-running series is being shifted from Los Angeles to New York, and host Jay Leno is being replaced by Jimmy Fallon.

McManus told AAP he is returning to the US to catch up with the LA team of the Today Show and to make one last appearance on the show.

He was not expecting to be called-up to be a regular guest alongside Fallon.

"I'm back to LA because there's one final spot with the Tonight Show before they wrap up," McManus said.

"It will good to go back and say farewell to those guys; they have been very good to me the last five years.

"They're finishing up for good, well for now it seems, and Jimmy Fallon is coming in and it's being shot out of New York.

"I don't know what that means for me long term, but my involvement with the show out of LA will be finished when they finish."

The timing of the Tonight Show changes could be considered fortunate for McManus, who became a father in December when his wife Tasma Walton gave birth to Ruby Aurelia.

While he will miss appearing alongside Leno and working in LA, he'll have more time to spend at home, changing nappies and helping around the house.

"She's only quiet for him," Walton said with smile.

McManus said he was likely to spend more time in Australia in 2014 and was working on a new project.

"There is something new I am working on at the moment, but I can't say too much," he said.

Fallon will host the Tonight Show from February 17.
