Rose Matafeo represents New Zealand, talks getting heckled by her nan on The Graham Norton Show

Rose Matafeo has checked off another show business milestone by appearing on The Graham Norton Show

The Kiwi comedian appeared alongside actor and director Sir Kenneth Branagh, Line of Duty star Vicky McClure, Rachel Zegler, the star of new film adaptation of West Side Story, and Scottish singer-songwriter Emeli Sandé.

"I don't know why I'm here!" Matafeo joked as host Graham Norton pointed out it was her first time on the show. 

The 29-year-old discussed the upcoming second season of her BBC show Starstruck, as well as reflecting on her upbringing in Aotearoa and using her family as material for her early standup shows. 

"Because I was so young when I started, I had no life experience to base my observational material on," she laughed. "So it was mainly about my family." 

"I had a weird upbringing and I didn't really realise that until I started talking about it on stage and people were like 'I don't relate to that!'," she said. 

Matafeo recalled one show where she "ripped into" her nan about the way she pronounced the word muesli, only to be heckled by her nan from the crowd. 

"From the back of the room she went: 'Next time I'll make you something different, then!' [She was] trying to like, slam me, but it was the most polite heckle of all time." 

Later, the Funny Girls star grilled a fellow Kiwi who appeared on Graham Norton's famous 'Red Chair' segment, in a bid to find out whether they knew each other. 

Matafeo's episode of The Graham Norton Show will air in New Zealand on February 3 at 8.30pm on Three, and will be available on ThreeNow.
