Criminals are funnelling billions of dollars of “dirty” cash through pokies in NSW pubs and clubs every year as the machines remain a “safe haven” for money launderers because of weak regulation, a major inquiry has found.

The NSW Crime Commission, which led the review, said it could not tell how much of the $95 billion fed through pokies in the state annually were proceeds of crime, but it was “many” billions, primarily from drug dealing.
