Kiri Allan's arrest has raised questions about Labour's chances in the upcoming election.

Ginny Andersen has taken over as Justice Minister from Kiri Allan - who was charged with careless use of a motor vehicle and refusing to accompany a police officer in Wellington last night.

She's the latest Minister exiting Cabinet in recent months, following Stuart Nash and Michael Wood.

Former Labour Chief of Staff Mike Munroe says Kiri Allan's departure is another sorry chapter for the party- but there's 80 days left to go.

"The concerns that people have got are the concerns around law and order, crime and the cost of living. And we'll find that those issues are going to be front and centre of the political conversation over the next 80 days."
