Christopher Luxon is ruling out welfare cuts and state asset sales if National leads the government after next year's election.
After six months in the job Luxon is rebranding the party - promising strong action on climate change and a return to standing in the Maori seats.
He spoke to Guyon Espiner about what drives him and drew some important lines in the sand, including a pronouncement that he won't follow the lead of previous National governments by selling state assets.
Political commentator Ben Thomas, a PR consultant and a former National Government press secretary, spoke to Susie Ferguson.
