Winston Peters says it's no longer tenable for Speaker Trevor Mallard to stay in his job.

Mallard has withdrawn trespass orders against five people who attended the recent anti-mandate protests - all former MPs.

Two other people who attended the protests will continue to be banned from visiting Parliament Grounds for the next two years.

The New Zealand First leader told Mike Hosking Mallard has misunderstood what the role of Speaker should be.

He says the bans were a thoroughly political act, by a person who is supposed to act in a politically neutral way.
