Newstalk ZB senior political correspondent Barry Soper says Chris Luxon's now faced with the knowledge there's several detractors in his caucus. 

The Prime Minister's survived a second vote of confidence in a matter of months, following an urgent caucus meeting which lasted close to three hours. 

He says the Prime Minister has to avoid wreaking havoc on the party and not immediately penalise those who plotted against him. 

"He's got to live with that, that's the nature of politics. Between now and the election, at least - after the election, all bets are off."
