Mitchell tweeted about the episode yesterday, and Matafeo's inclusion was celebrated by many on Twitter.
"WOOP! love rose matafeo [sic]," tweeted one user, while another tagged Matafeo saying she was "brilliant" on the panel.
Matafeo is living in London with her comedian boyfriend James Acaster, returning to Auckland earlier in the year to shoot the second season of Funny Girls, a sketch show comedy featuring a number of up and coming young comedians.
Fellow Kiwi comedian Guy Williams tweeted in support of his friend, saying she was on the show "hosted by god dang DAVID MITCHELL. So good! NZ media, turn this tweet into an article NOW! [sic]."
You're welcome, Guy.
