NSW Police Commissioner Mick Fuller says he has "never seen looting like I've seen during this emergency", as a police crackdown on theft and criminal activity in fire-affected towns resulted in no charges related to theft.

"I’ve never seen looting like I’ve seen during this emergency. It’s a disgrace and it made me sick to the stomach," he told radio 2GB on Tuesday.

"Part of what I need to make sure is we’re putting the right amount of police into these areas.

"I was on the ground in a recovery centre south of Batemans Bay and every second person I spoke to either had someone try to get into their house or their neighbours had someone trying to steal something from them."
