"We don't want it to turn into a circus or anything like that. It will be a proper game with two 40-minute spells. There will be the ability to change within each team but that is not what we are planning to do.
"We will have pretty set structures about the amount of time people will play. It is a midweek game and we are getting to the end of the club season so we aren't going to overload any player, given that they are having to back up on Saturday."
The trial teams did not include players involved in Super 15 or the World Rugby Under-20 Championships.
The trialists will train together at Te Puke Sports on Monday, June 15, at 6pm.
After the trial, the Wasps team would be named to play the Cavaliers in the first pre-season match on June 24 in Katikati. This is the final opportunity for players to put their hand up for the 2015 Steamers ITM Cup team, named mid-July ahead of two ITM Cup pre-season matches against Auckland on July 31 in Whakatane, and Manawatu on August 6 at Tauranga Domain.
Steamers trial: June 17, Rotorua International Stadium, 6pm
