The NZ Maori team will assemble straight after the finish of the provincial tournament before departing for Toronto.
"Selection is the key because it's quite a tough tour," Cooper said. "We meet and we're playing six or seven days from the meeting because of the ITM Cup. We've got to get the selection right and we've got to get young men who are aspiring to be the best they can be."
The USA recently pushed Ireland extremely close in Houston, the Irish winning 15-12, and Cooper believes both matches will be extremely challenging.
"We're going to have to unite very quickly in order to be successful."
Cooper, a former NZ Maori player of Ngati Pukenga descent, said he would be in close contact with Matson and the All Blacks selectors during the ITM Cup in terms of selecting players.
"Our main drive is really to continue the good work that has been done. I guess it's about getting the best players to create a real high-performance team that's going to go out there and be proud of who they are and win."
