Police Minister Mark Mitchell says told Mike Hosking that police bodycams would help clear up misconceptions in the field.
He says he was talking to a young constable who was coward punched and a body camera would've made for compelling evidence.
Police Commissioner Richard Chambers wants the cameras to be implemented after a decision was put off last year.
Police are still looking into ways to deal with transparency issues laid bare when new tasers for frontline officers didn't include a camera.
