Orere's letter was penned by 10-year-old student Alysha-Marie Holmes. "We live a long way from Auckland," she wrote. "We would love to go to Queenstown because some of us have never gone on a plane. This would be a trip of a lifetime full of wonderful opportunities."
The decile-three school has a roll of 46 and Robson said they were "blown away" by the win.
He said most of the pupils had never been to the South Island before.
"A lot of the kids would never get the opportunities of students from more-affluent areas," he said.
The students lapped up country activities including cowpat and gumboot-throwing, a sack race, ducking for apples and a tug of war.
"We were so well looked after and we can't thank Jetstar enough for the hospitality," Robinson added.
Grant Kerr, head of Jetstar New Zealand, said: "It was fantastic to see the students having fun in the Jetstar Kids 'n' Country zone - they took the games to heart and we definitely saw some stiff competition between classmates."
