One National MP is feeling confident about a caucus reshuffle, under new leader Christopher Luxon

He's expected to reveal his first shadow cabinet in about an hour .

Former leaders Judith Collins and Todd Muller aren't likely to play a prominent role.

Deputy Nicola Willis is expected to stick with housing, and Chris Bishop, the Covid-19 response.

Bishop says it'll be a good match against Labour's Caucus.

He says it'll be a refreshed and rejuvenated team, and reflect Luxon's priorities as leader.
