New-entrant testing at year 9 identified high achievers, Mr Smith said.
"We have accelerate classes where all of those boys are put together. In year 10, a lot of them are doing NCEA ... so they're extended by doing NCEA."
High achievers were celebrated via an "Elite Performers" group which included top arts, academic and sporting pupils.
"They get to wear a special jacket and the first boys into that group are our top academics in year 12 and 13. We celebrate success all the time, so I don't think they feel any tall poppy syndrome," Mr Smith said.
Mrs Tapper said several surveyed students were concerned about getting a nerdy name, and most had been called a nerd.
"Able students are encouraged to be the best they can be but ... have learnt to keep quiet about their successes or else someone will turn around and be offended."
