Three people, including a man believed to be photographer Richard Green, have been found dead at the site of a helicopter crash in NSW'S Hunter region.

The wreckage of the helicopter, that had gone missing on Saturday evening, was found on Monday night in the Watagans National Park, south of Cessnock.

The Australian Maritime Safety Authority says no survivors were found at the crash site, which is in mountainous terrain and covered with dense vegetation.
