A former National cabinet minister says the party needs to move on from internal wrangling to the more pressing issues at hand.

Chris Luxon's passed a vote of confidence at yesterday's caucus meeting.

MPs aren't revealing details of the vote, including how many of them supported Luxon.

Former minister Chris Finlayson told Ryan Bridge the path forward, for National, is simple.

He says they need to deliver a good Budget, pass RMA reforms, sign the India free trade agreement, and start speaking highly of each other and campaigning in a unified way.
