Leach told the Rotorua Daily Post she was surprised but humbled.
"When I received it I was thankful and humbled. I felt so privileged to be in the same position as those before me.
"This will help me get the marks I'm looking at because that's my mentality. That I have to strive for excellence. I'll be getting mentoring from the best."
Leach said the awards ceremony was overwhelming.
"To be in a room with so much talent ... It's amazing to see the future of what our rangatahi are capable of."
Leach wants to pursue commerce and law at the University of Auckland. She also is a basketballer.
