Walker passed a fitness test yesterday. His inclusion gives the side added wheels to go alongside the likes of Josh Honey, who played his way into the side with an impressive showing at Blake Park, alongside the play-making abilities of Trinity Neera-Spooner and Te Aihe Toma and the size of players like Matt Clutterbuck, Brynn Uriarau and Ralulu Bavou.
"We haven't got a big team in the forwards, but we've got speed and fitness and players capable of not taking the ball into contact too much," Woods said.
Woods added the side planned to treat day one as day two, with the opening match against Canterbury representing a quarterfinal before subsequent clashes with Counties Manukau and South Canterbury.
The match against South Canterbury is the final game on the opening day, meaning the hosts will know the equation to finish in the top two of their pool should they split their opening matches.
