Wigan have signed Cook Islands international Anthony Gelling from Auckland Vulcans.
The 21-year-old, who can play at centre or second row, previously played for another NRL side Sydney Roosters.
Gelling, who stands 6ft 5in tall, will begin pre-season training in Florida this week.
"Anthony comes highly recommended and, having studied his career, I am sure he has the attributes to make a massive impact," said Wigan coach Shaun Wane.
New Zealand-born Gelling featured for the Roosters in the Toyota Cup in 2009 and 2010 but was dismissed from the New South Wales club for an alleged off-the-field matter in September 2010.
He returned to the country of his birth to join the Vulcans this year.
"He may be unknown to the public in the UK, however, some of English rugby league's most successful imports have come over with similar reputations," added Wane.
"Players like Kevin Iro, Henry Paul, Frano Botica and even George Carmont were little known over here but proved to be world-class acquisitions.
"I know he has learned from his experience both at the Roosters and in New Zealand and comes to the club fully prepared to buy into the Wigan culture and establish himself as a first-team player."
Gelling, seen as a replacement for rugby union-bound Joel Tomkins, added: "It will be an honour to play for the world-famous Wigan. I've already heard about how passionate the Warriors supporters are.
"I know the squad is packed full of talent so I will have to work hard to earn the opportunity to show the coaching staff and fans exactly what I can offer."
