''It's about how hard these boys have worked in the off season over the last couple of years. It's not just a one year thing, they have actually worked hard over the last couple of years, so they deserve the opportunity.''
The standard of competition being played was also crucial.
''It's also a reflection of the quality of rugby we play in the Super 8 competition. It's a hard competition week in, week out, and for a school boy to be playing that week in, week out, is huge. Obviously they are going to grow as a rugby player and these three have certainly done that.''
Trask has already signed a contract with the Bay of Plenty Steamers Academy and Perham and Whata could also be heading into the professional ranks.
''I hear they're in talks with other unions at the moment, but they are keeping their feet on the ground. They are over the moon and the school is really proud of them, and it's exciting that our model's working at Rotorua Boys' High School. To get three boys in there and for them to be at the top level, it's awesome for the school.''
Trask and Whata are both Year 13, while Perham is still in Year 12.
''Hayze has worked really hard, and for a Year 12 to get in there is awesome,'' said Simpkins.
While Trask has played fullback several times this season, Simpkins sees him as a first five, the position he has been named at in the secondary schools squad.
''I've always thought he was an outstanding first five, but what he can bring in terms of speed at the back is the reason we've played him at the back. But I definitely think his leadership at 10 means he is going to really stand out there.''
