Surprised? You shouldn't be. Sinha says The Chase host Bradley Walsh has been introducing him on the show as a "doctor and comedian" for some time.
Chase fans may be disappointed to know that there's "really no connection" between Sinha's quizzing and comedy, but his time on the show does make for some good stories, which he shares in a standup set described as "storytelling with jokes".
"I've got a very unusual life as - as far as I'm aware - the only openly gay, British-Asian, qualified doctor and competitive quizzer in the international comedy scene. You'd be astonished the number of stories that give you really," he told Breakfast.
However, he does say that being on The Chase has helped him tremendously.
"It's a privilige really to be on TV ... it's also helped my comedy career a lot because people know who I am now. That changes your life."
Paul Sinha will perform in the Best Foods Comedy Gala - an event which kicks off the International Comedy Festival - alongside James Acaster, Rhys Nicholson, Urzila Carlson and Melanie Bracewell at the Civic Theatre on May 2.
The two-and-a-half-hour show will be broadcast on TVNZ.
This year's comedy festival runs from May 2-26. The full line-up will be revealed on February 28, the same day tickets go on sale.
