"The trial is vital for Wigan ahead of the World Club Challenge against the Sydney Roosters but it's also important for us as we build towards our final preseason hit-out against Brisbane [in Dunedin on February 23].
"With this trial coming only three days after the Gold Coast match and three days before the NRL Nines, our depth is being tested this week but that's really what trials are about.''
Wigan fly out of England this weekend soon their opening Super League match against Huddersfield on Friday night. They're due to arrive in Auckland on Monday afternoon before transferring to Hamilton where they'll train on Tuesday morning. After the trial they'll set up base in Auckland where they'll train and attend the nines.
