Winston Peters labels Green Party as 'communists' but praises James Shaw in game of 'kiss, kick or marry' on The Project

Winston Peters has likened the Green Party to communism while simultaneously complementing its co-leader in a cheeky game of "kiss, marry or kick".

Appearing on The Project on Friday night, the NZ First leader was tasked with playing "kiss, marry or kick" with the options of ACT leader David Seymour, Greens co-leader James Shaw and Te Pāti Māori co-leader Rawiri Waititi.

He chose to kiss Seymour. Earlier polling has suggested the National Party may need to form a three-way coalition with ACT and NZ First after the election, meaning Peters and Seymour would have to work together.

Peters then said he would marry Shaw, delivering a back-handed compliment where he praises the Greens co-leader but hits out at his party.

"James is a guy that I think is horribly in the wrong place, he's in the wrong party, in the sense he's for the real environment and the rest are for communism, frankly," Peters said.

"They've got a thousand ways to spend money and not one way to make it."

This left Waititi as who Peters would kick.

"I don't understand how you can be so anti the colonial and yet have a cowboy hat," he said about the Te Pāti Māori co-leader.

"He is never going to forgive me for saying it."
