In addition, the Wasps fixture will be the first appearance for Shahn Eru and Terrence Hepetema, who are both now playing for Te Puna, having arrived recently from Italy and the United Kingdom. Whaka's Whaimotu Craft-Chemis will also make his first appearance returning from injury.
The trial does not include players involved in Investec Super 15 or the World Rugby U20 Championships.
The Wasps versus Cavaliers match will be one of the last opportunities for players to put their hand up for the 2015 Steamers ITM Cup team. The team will be named mid-July ahead of two ITM Cup pre-season matches against Auckland (Friday, July 31 in Whakatane) and Manawatu (Thursday, August 6 in Tauranga).
