There are four uncapped players on the bench - Tom Court, Ryan Caldwell, Jonathon Sexton and Frank Murphy.
Interim Ireland coach Michael Bradley said: "Barbarian games are always exciting, high-tempo matches.
"From that perspective it will be good preparation for us as we head into the tour where the teams have been playing a fast and loose game under the new experimental law variations.
"The match will be important for the players to get up to that pace of play before we arrive in New Zealand and also for the Churchill Cup players in the match squad ahead of their tour."
