Barry Soper: ZB senior political correspondent on David Seymour ruling out a collaboration with Winston Peters - Heather du Plessis-Allan Drive

ACT's drawn a line in the sand- saying its MPs won't sit around the cabinet table with Winston Peters or his MPs.

NZ First scored 4.1 percent in the latest Newshub/ Reid Research poll, edging up to the 5 percent threshold.

But David Seymour confirmed he won't be in a Government where Peters is in Cabinet.

ZB senior political correspondent Barry Soper says he's not surprised David Seymour ruled out working with Peters- but Luxon shouldn't turn down NZ First.

"I don't think Chris Luxon should rule out Winston Peters, because in this business of MMP, you need all the political parties you can get."
