The Warriors have confirmed the signing of Sydney Roosters fullback Roger Tuivasa-Sheck on a three-year NRL deal.

The 21-year-old Kiwi star will join the Auckland-based club from next season.

The Warriors also confirmed unsettled England fullback Sam Tomkins will be granted an early release from his three-year Warriors deal, allowing him to return to Super League club Wigan.

Tomkins, who has been sidelined by a knee injury, will leave at the end of the season.

According to reports, the Warriors offered Tuivasa-Sheck a contract of more than $800,000 a year – double the $400,000-odd the Roosters’ offered.
