This season's ITM Cup game priorities were developed following discussions with those involved in the game, particularly ITM Cup coaches, and take trends into consideration that have emerged throughout the 2015 Investec Super Rugby competition.

Harris and Macleod have the bulk of their squad available for tonight's match with the exception of Dan Bowden, Dan Pryor, Daniel O'Rourke and Kara Pryor (injured), while Josh Goodhue, Sam Nock, Matia Navares, Filipo Nakosi and Isimeli Taqea will be unavailable due to their involvement with Mangonui and Bay of Islands premier club finals.
Jone Macilai will get some game time after recovering from his foot injury, however, Harris will keep a close eye on his rehabilitation. "Anyone that's 50/50 we've scratched."
