Rugby World Cup organisers are chipping in $30,000 towards a new $65,000 sprung wooden floor at Wakatipu High School.
The gym will be used as an indoor training arena for the Georgian and Romanian squads during the cup.
Lakes Leisure events manager Jason Marrable brokered the deal with cup organisers after Queenstown was allocated extra training days following the February 22 Christchurch earthquake.
"It's a win-win situation for everyone - for the community and for current and future pupils at the school," he said.
The floor, scheduled to be installed by the last week of August, would be a "great legacy" from the Rugby World Cup.
"You have to have a welcoming and comfortable gymnasium for kids to be interested, to get them away from their PlayStation and computers. Anything that gets kids off the couch and on to the basketball court; we live in an active country where a lot of kids are inactive," he said.
England and Ireland will train at the Queenstown Events Centre and school board property manager Wayne Foley said Romania and Georgia had chosen the school gym for inside training.
The gym's present concrete floor is not up to RWC standard and Mr Foley said with the building of two new classrooms and entrances to the gym the timing of the offer was a "perfect opportunity to complement that - we're thrilled the Rugby World Cup were able to support us in this way."
One option had been to hire a sprung floor for $30,000, but it was decided the money was better put towards a new floor.
It was hoped the shortfall could be made up with a Queenstown company or organisation paying $10,000 for naming rights to the gym with the school's board of trustees paying the $25,000 balance.
"We've committed to the floor, because the opportunity won't come around again," Mr Foley said.
Although the new floor might only be used for a few years - the Ministry of Education is looking into acquiring land at Frankton Flats to relocate the school as early as 2016 - Mr Foley said it was still worthwhile as both a school and community asset.
"We're not aware that negotiations have been concluded but even if they were, it could very well be another five to seven years before the school's completed. In the meantime, it's vital that teachers and students have the best environment available," he said.
