NRL chief executive Todd Greenberg has vowed to dish out a lifetime ban to any player found guilty of match-fixing following allegations made on Thursday.
New South Wales Police has launched an investigation after claims that players were paid to fix NRL matches last season.
NSW state police confirmed its organised crime squad was investigating the matter and Greenberg said the NRL will do all they can to assist with the matter.
"Whatever the police require they will get from the NRL Integrity Unit," the NRL CEO said.
"If any allegations are proven and individuals are found guilty, we will ban them for life.
"We must be careful not to jump to conclusions. But we will take the necessary steps to protect the game.
"I'm not going to talk about any specifics, individuals, rounds or clubs.
"We will always confront issues in rugby league. And we will always deal with these issues.
"I will talk to all 16 NRL club CEOs after this briefing."
This is not the first time the NRL has been embroiled in a match-fixing scandal.
Ryan Tandy, who died in 2014, was in 2011 found guilty of a plan to manipulate the first scoring point of a game in August 2010 between the Canterbury Bulldogs and North Queensland Cowboys.
