Orewa captain Lewis Gjaltema, who played No 10 for his First XV, is named as a halfback.
The squad will meet in Palmerston North on Saturday for a development camp, from which the separate squads will be finalised. The NZ Schools will play the NZ Barbarians Schools for the first time on September 19 at Palmerston North BHS before the top side embarks on a three-match tour of Australia, playing Samoa Schools on September 24, Australian Barbarians Schools on September 28 and the October 2 Trans-Tasman Shield test at Ballymore against Australian Schools in an annual fixture that goes back to 1978. The coveted Bronze Boots, for the best player on either side, will be up for grabs in this international. NZ Schools have not lost this game since 2012 in Auckland.
New Zealand Rugby high performance talent identification manager Matt Sexton said there was good reason to feel upbeat about this year's group.
"As with previous years, the panel is again happy with the level of talent and coverage across most positions. With such a fantastic season of secondary school rugby, it was great to see strong competition for places. Based on what we have seen this season, and the level of talent in squad we have selected, it augurs well for the future," said the former Canterbury and Crusaders hooker.
