Both agree Koroi fully deserved his inclusion in the wider All Blacks Sevens training squad. The only surprise was how rapidly he had progressed.
Malcolm and Mason were both slightly surprised he had received the call at 16.
"He's a very talented player with natural flair and very quick. You name it he can do it," Mason said yesterday.
"It doesn't surprise me he has made the All Black Sevens squad, the only surprise is he got the call at just 16-year-old. He deserves it though and it's primo - awesome."
Malcolm said he had always shown real promise.
"I'd heard he made the squad and that's great. He was a big part of both our 15-a-side and sevens teams at WHS and the school is very proud of him. I must admit while he deserves his chance, I was a bit surprised given his age," Malcolm said.
Koroi will be joined in camp by fellow schoolboys, Elias Goodhue and Nathaniel Apa.
