The players who are locally based were selected based on their performances at the Tri Series last year and the Nines competition earlier this month.
The team coached by Bobby Hansen will be trimmed to 25 and eventually to a final 15.
Cook Islands Rugby League official Tai Nelio said coach Hansen was very happy with the keen interest of many local players who have put their hands up to represent the Cook Islands at the Pacific Games.
Nelio said many Cook Islands overseas players have also asked to join but they could not because they do not meet the games criteria.
The Pacific Games criteria include players have to be born in the Cook Islands, or have resided here for five years, be a Cook Islands resident and have a New Zealand passport.
The training squad comprised some experienced players who are leading their respective teams in the domestic competition.
“Experienced players like Eric Newbigging, Ozwel Tunupopo, Aiden Anunga and Sato Wale will inject depth in the team. As well as the inclusion of the Iro brothers Kayal and Andre and Chedyn Mani who will add speed and balance in the team,” Nelio said.
“Players will be picked on form not reputation.”
