The NRL has announced Head of Football Todd Greenberg as its new CEO.

The NRL said on Wednesday it will support and provide any assistance requested by the Police investigation into match fixing.

CEO Todd Greenberg reiterated that there is no place in Rugby League for any person found to be involved in match fixing.

"We are not going to pre-judge any person associated with the game while this process is under way," he said.

"But I repeat my earlier warning that if any person is convicted of match fixing they will face a life ban from any involvement in Rugby League."
