This is the second year Ireland 'A' are competing for Churchill Cup honours. Last year's tournament, staged in Canada and the USA, saw the Bradley-coached side lift the Plate title.
Commenting on the 2007 competition, Michael Bradley said: "We have three tough tests coming up but if we perform to the best of our ability I believe these players can gain great experience from the competition.
"Three of our starting line-up - Johnny O'Connor, Jeremy Staunton and Roger Wilson - have been capped at full international level so we'll be looking to them to be leaders. Also, there are some exciting young players who have the opportunity to show us what they can do.
"Canada and the New Zealand Maori offer international class opposition so this tournament will play an important role in developing the players' experience at this level," added the former Ireland scrum half.
The team selected for Saturday's match includes two of the Irish Under-20s' Grand Slam-winning heroes - centre Darren Cave and winger Keith Earls.
