Sonny Bill Williams has signed a two-year $10 million deal with Toronto Wolfpack, according to Nine News reporter Danny Weidler.
It stands as the most lucrative deal in either rugby code's history.
“There’s been a lot of speculation about what Sonny Bill’s next move will be,” Weidler told the Nine News Bulletin.
“It will be to return to rugby league. Not in the NRL, he’s made his mind up to join the Toronto Wolfpack, who play in the English Super League.
“The deal is stunning — $10 million for two years’ work. Incredible money there. Probably the biggest deal that I’ve ever heard of in rugby league or rugby union.
An official announcement is expected to be made within the next week ahead of an official function and jersey presentation at Canada House in London.
The 34-year old had a number of NRL suitors as well as big offers from French rugby union clubs as, neither of which could compete with the Wolfpack's bid.
He completed his All Blacks career on Friday as New Zealand ousted Wales to finish third in the Rugby World Cup Finals.
The Worldpack are still believed to be on the lookout for more big-name signings following their promotion from the second-tier Championship.
Earlier this year, Wolfpack owner David Argyle said there were "10 superstar names" on a wish list.
