A warning to the paparazzi from the Prime Ministers minders.

Parliament Speaker Trevor Mallard is threatening to expel Press Gallery journalists if they take unauthorised photos of the Prime Minister or Clarke Gayford on their return next week.

Newstalk ZB Political editor Barry Soper says Mallard is promising that if his rules are breached, he will withdraw the offending journalist's accreditation and penalise their employer.

Mallard says he wants to make Parliament more family friendly. He has posed in the Speaker's chair holding an MP's baby.

As an example, if the first couple happens to walk behind an interview being videoed with baby Neve, he expects that part of the interview to be deleted.

The Gallery will meet Mallard next week.
