National is calling on Police Minister Poto Williams to resign following her comments on Newstalk ZB's Mike Hosking Breakfast today.

The Minister pushed back at the suggestion the police should be armed, and says the communities she represents - Māori and Pasifika - are against arming officers.

National leader Judith Collins says Williams should be replaced by someone capable of caring about police officers.

Ms Collins told Heather du Plessis-Allan firstly, Ms Williams representing claims are incorrect.

"You've got a minister there who says she represents Māori and Pasifika communities - no she doesn't, she doesn't at all. She represents Christchurch East.

"I can't imagine too many people in Christchurch East agree with her pathetic response when asked to condemn the activist group People Against Prisons Aotearoa, who want to disarm, defund and abolish what they call the blood-stained, racist institution that of the New Zealand Police. She couldn't even stand up for Police then.

"Police can't come out and fight for themselves when it comes to the media, the least thing they want from their Minister is to have some spine and to stand up for them, and if she can't do that she should go."

Collins believes Ms Williams has lost the confidence of the front line.
