Christopher Luxon says he wants nothing to do with the Greens, while he's Prime Minister

Luxon's confirmed a National-Greens Coalition wasn't off the cards, when James Shaw was co-leader of the Green Party.

But he says the party has changed significantly under new leadership.

The PM says he had great respect for Shaw and his commitment to the environment, and would have been prepared to work with him.

But he says the Greens have since moved to what he calls a more "socialist" position.
