The 17-year-old says his two favourite sports, hockey and swimming, have more in common than many may think.
"Although they seem very different sports both rely on individual skill.
"As goalie you have to commit to stopping a shot at goal - even if someone tees off on the front foot and I have stopped a few which hurt. But both sports are fast paced and require explosive speed and focus."
Rob says although he was "forced to start swimming" when he was 5, he now trains for up to two hours, four days a week before competitions.
He has grown to love the sport and lists a recent highlight as winning division II national 50m and 100m backstroke events in Wellington in April.
Rob has also represented Central Otago men's hockey representative (Ian Smith tournament 2007-08).
While he says being a prefect has not cured him of an aversion to public speaking he has enjoyed more involvement in school management, and thinks the leadership roles he has assumed this year may help "in the board-room in future."
