Act leader David Seymour believes Christopher Luxon will likely be National's new leader.

Luxon appears to have decided to run for the leadership and may have the edge over Simon Bridges in terms of numbers.

Meanwhile, fellow possible contenders Mark Mitchell and Nicola Willis aren't giving anything away ahead of tomorrow caucus meeting.

Seymour told The Country the party needs to make a show of starting a new chapter.

“If I was to look into a crystal ball, I’d say they'll go with Luxon because they need to break the pattern that they're stuck in.”
