Eight players who were not involved in the Under-20 Six Nations Championship have been added to the squad.
Diarmaid Dee, Dylan Donnellan, John Madigan, Darragh Moloney and Craig Trenier are named in the forwards, while Billy Dardis, Ryan Foley and Ciaran Gaffney join the backs division.
Four of the squad featured in the 2013 Junior World Championship last summer - forwards Peter Dooley, Jack O'Donoghue and Peadar Timmins and full-back/winger Alex Wootton.
Connacht's Sean O'Brien will captain the Ireland U-20s for the June tournament. He was skipper during the recent Six Nations in the absence of Dan Leavy, who misses the Junior World Championship through injury as does his UCD and Leinster colleague Adam Byrne.
Ireland share Pool B with Six Nations winners France, Fiji and Wales. Mike Ruddock's youngsters open their campaign against the French at QBE Stadium in Auckland on Monday, June 2.
