"Of course playing in Denver brings with it some unique considerations but having experts on board like Greg Macleod allows us to be prepared in the best possible manner," Kiwis manager Nadene Conlon said.
The Warriors are likely to have at least eight players eligible for selection but CEO Cameron George has previously said none will be released unless they are 100 per cent fit.
The test will take place between the rounds 15 and 16 of the NRL competition, with Warriors players having to return from their clash against the Cowboys in Townsville on June 15 before embarking on the flight to the US.
The weekend following the test, the Warriors are set to host the Cronulla Sharks at Mt Smart Stadium on June 29, but it is doubtful whether any of their Kiwis representatives will be asked to back-up just three days after arriving home.
Warriors forward and Kiwis 2017 World Cup captain Adam Blair says he is supporting the NZRL's commitment to the Denver test.
"It's exciting for international rugby league and New Zealand have jumped on board trying to change things around New Zealand rugby league," Blair said.
"I'm supporting the game for what it is and if I'm selected then I definitely won't be turning down a Kiwis jersey at any time."
Applications for the vacant Kiwis coaching job close today with the NZRL's coaching appointment panel set to interview interested candidates before making a recommendation to the NZRL board which will finalise the appointment.
