Mapusua has the experience and rugby knowledge of four former All Blacks and one Wallaby player in his squad.
He has named former Wallaby fly-half Christian Leali'ifano and ex-All Blacks Charlie Faumuina, Steven Luatua, Jeffery Toomaga-Allen and Lima Sopoaga along with a handful of Moana Pasifika players from the Super Rugby Pacific competition.
His squad will assemble in Apia on July 1 to start their build up and have matches against Japan, Fiji, Tonga and Ireland on their way to France.
