TV and radio presenter Hayley Holt will stand for the Greens at the next election, possibly even going up against the Prime Minister.

The announcement comes soon after third-placed Auckland mayoral candidate Chlöe Swarbrick signed up with the party, and co-leader James Shaw is teasing more big names are to come.

Ms Holt, 36, announced her candidacy on Monday, having formally signed up to the party's list. She hasn't been picked for an electorate contest yet, but Rodney - considered a safe National seat - and John Key's electorate of Helensville have been considered.

Mr Key has held the electorate since 2002, four years before he was elected as National's leader in 2006.

Mr Shaw says he's delighted, and Ms Holt is just the latest in a number of "really strong candidates" who will make themselves known over the coming weeks.

He says her lack of political experience is something all new MPs need to grapple with.

"Nobody has any experience until the first time they do it. If you look at Hayley's record in the sports world, and in the media, she brings a lot of skills to it - as do a number of other candidates.

"People come from all walks of life, and the point of the House of Representatives is that it is representative - that it represents a broad spectrum of society."

Ms Holt's television career so far has included sports show The Crowd Goes Wild, political pub panel show Back Benches and as a judge on Dancing With The Stars. She's also been a competitive snowboarder and dancer.

Ms Swarbrick announced she was joining the Greens last month. The 22-year-old posted her announcement to Facebook and Twitter, saying there's a "tide for change" in politics.

Mr Shaw says future candidates will come from a variety of diverse backgrounds.

"The great challenge is going to be getting everyone into Parliament."

Ms Holt has been approached for comment.
