The Greyhound Racing NSW board and chief executive Brent Hogan agreed to stand down on Wednesday night in the wake of the live baiting scandal engulfing the sport.

Deputy Premier and Racing Minister Troy Grant spoke with each of the board members personally before the decision was made.

The move came after Monday's Four Corners expose on the dark side of the sport. The program featured piglets, possums and rabbits being used as live bait to blood greyhounds.

While there was footage from Queensland and Victoria, there were disturbing practices shown on NSW properties.
