The fight against terrorism and organised crime as well as bolstering community policing will be key areas for incoming NSW Police Commissioner Mick Fuller, who has labelled the sought-after appointment his proudest career moment.

Hours after receiving the phone call informing him he would take the top job, news that nearly caused his wife to "pass out", Mr Fuller outlined his vision alongside Premier Gladys Berejiklian and Police Minister Troy Grant.

The 49-year-old flagged a different leadership style to that of his predecessor, Andrew Scipione, which will change a policing model that has existed for 20 years.

"I think I have a different brief to him in fairness and my brief is about moving NSW Police into the future," he said at Parliament House on Thursday.
