Wigan Warriors have confirmed that Sam Tomkins will join New Zealand Warriors next season.

The Super League club will receive what is believed to be a world-record fee for the 24-year-old Englishman, who has signed a three-year deal.

However, the agreement gives Wigan the first option of re-signing Tomkins if he decides to leave New Zealand.

"We are extremely disappointed to be losing a player of Sam's talent and ability, but Sam's determination that now is the time for him to be taking up the personal challenge of playing in the NRL (National Rugby League), is the driver of this deal at this time," Wigan owner and chairman Ian Lenagan told the club's official website.

Tomkins has made 150 appearances for Wigan since signing his first professional deal with the club in 2008.
