OFF: Rhys Darby has upped sticks and moved to the US with his wife Rosie and their two children.

Rhys Darby has set up base in the US as he chases his comedic fame and fortune.

The popular stand-up comic, star of the Flight of the Conchords TV show and sometime movie actor has been touring his latest stage show in America.

And he revealed that America was now firmly a focus for him as he looks to cash in on his comedy routine.

"I've been here since July, although I've been back and forth doing various things for awhile," he told Denver-based heyreverb.com.

"But we got our green cards, so the family and I kind of made more of a permanent move here."

Darby last year completed an "extensive" tour of the United Kingdom. It was likely that he would repeat that exercise in 2014.

The 39-year-old - who starred in the popular 2009 movie, The Boat That Rocked - is also considering a feature tour of the US.

Recent shows in America were a way of "dipping my toes in, seeing who turns up".

"I've been doing sporadic gigs in places I haven't been to since I got back this time around," he said.

"And I got the opportunity because of being well known from things I've done in the past, which have given me the chance to show up to these places and to have comedy clubs go, ‘Yeah, we'll have you'."

His link to Flight of the Conchords chelped too, Darby said.

"That show on HBO was pretty popular and there are Conchords fans everywhere. It helps that they keep touring as well. People come up to me with their DVDs that Bret [McKenzie] and Jemaine [Clement] and the other guys have signed and said, 'Can you complete this for me?' "
