The Police Commissioner says he's aligned with the new Police Minister on the changes needed for law and order.

Minister Mark Mitchell has publicly released a letter, outlining his expectations for Commissioner Andrew Coster.

That includes refocusing efforts on strengthening policing in communities, removing gang patches and cracking down on youth crime.

Coster says officers essentially need to spend less time doing the business of others.

"Which we do substantially in the social arena, particularly family harm where there's no violence, mental health- we need to be able to increase our visibility."
