Mr Mangan said the school was acknowledging each athlete's achievements in assemblies and the school community was supporting the former students all the way.
''We are all about raising good men,'' he said.
''It's about having confidence that you are well equipped to step out into the world with self belief. It's about raising those same qualities [...] Those are the same skills [you can apply] in the classroom, sportsfield and cultural arena.''
Meech, Saunders and Burling all attended Tauranga Boys' College at the same time.
Burling, with Tuke, was selected as the New Zealand flag bearer at the Olympics' opening ceremony.
''It's about setting goals and going for them,'' Mr Mangan said.
Burling is also the 2015 World Champion in the International Moth. He is the helmsman for Emirates Team New Zealand's 2017 America's Cup campaign.
