Star forward Andrew Fifita has re-signed with the Cronulla Sharks for another four years.

Kangaroos prop Andrew Fifita has re-signed with the Cronulla Sharks for another four years, a month after a proposed move to the Canterbury Bulldogs collapsed. 

The 24-year-old star, who represented New South Wales and Australia last season, will now remain at Cronulla until at least the 2018 season.

"I'm very happy to have it done and I can now concentrate on playing football," Fifita said. "I'm really looking forward to the next four years here at the Sharks, to winning a premiership and to helping to create some history for this club."

Sharks coach Peter Sharp said the signing would allow Fifita to put his full focus back onto his on-field performances this season.

"Andrew is one of the best front rowers in the game and his signing is a very much a positive for this club," Sharp said. "We look forward to him leading the way for this club not only for the rest of this year but for the next four seasons as well."
