A senior NRL player's phone has already reportedly been seized and NSW Police will interview at least six current stars as part of the match-fixing investigations.
Interviews by a strike force set up by NSW Police on Wednesday, with the backing of the NSW Crime Commission, will go for over four months according to News Corp Australia.
Players will face immediate jail time of up to six months if they fail to answer questions.
It's believed Strike Force Nuralda will look into three Manly games, including losses to Parramatta and South Sydney last year, as well as another against the Eels this season.
Reports also claim allegations centre around players being paid $50,000 each to throw a of match last season, with a $700,000 bet placed.
Prominent gambler Eddie Hayson, who has a number of links to NRL players, has continuously been linked with the matter in the media.
However he denied any allegations on Wednesday.
"Nobody's gonna get me for match fixing because it doesn't exist," he told 2GB.
"There wouldn't be six players over there that would cheat on their girlfriends let alone a match. That's how square the Manly boys are, it's a complete joke."
NSW Police confirmed in June they were looking into the possibility of match-fixing in the NRL.
According to Fairfax Media, they have spent the months since then trawling through betting records at corporate agencies and individual activity to locate a money trail.
"Police will work closely with the NSW Crime Commission, and have the full support of the NRL," a NSW police statement read on Wednesday.
"The investigation is expected to be protracted, with dozens of players, officials and members of the community expected to be interviewed in the coming months."
Anyone found guilty of fixing could face up to 10 years jail, with the NSW Government introducing tougher anti-cheating laws in 2012.
