The three matches in Australia marked the best preparation the New Zealand Under 20s have ever enjoyed as they aim to win the world title for the first time since Mark Anscombe's class of 2011, which spawned no less than nine All Blacks.
The class of 2015 counts a whole host with Super Rugby and ITM Cup experience.
"We really got to test our combinations and to put the boys under some pressure in both the tournament environment with short turnarounds between games, and the competition for positions," said coach Scott Robertson.
"Our locks are big, tall and strong with the likes of Geoff Cridge coming out of the Hurricanes. That makes a massive difference for us along with guys who have been really focussed on their core roles and aerial skills.
"Otere will lead our backline, he's a strong leader, he's played ITM Cup, and he's in the Hurricanes wider training group. He'll lead us around the field well.
"We've got a good mix across the backline helped by the power that Nathaniel Apa brings. We've got a bit of pace, guys who can play in different positions and we've got depth in our squad, which is really exciting for us."
