Te Ranga School's recent Pig and Possum Hunt raised over $20,000 for the school.
Principal Brendan Wilson says the silent auction alone netted over $6000.
Money from the event was tagged for fitting out and providing equipment for new classrooms being brought in to cater for the growing roll and for a Year 7 and 8 trip to Christchurch.
Brendan says because of the amount raised, there is also the chance to "do a couple of extra things".
"One of those is to move the library which is out on the field where it's been misplaced by the ministry, and we've been offered to have extra decks and things that we can now fund ourselves."
Brendan says the Pig and Possum Hunt, which was held for the 21st time, is part of the school's and local community's identity and culture.
"It's the thing that pulls us together, the families working together the day before and after to erect tents and all those sorts of things are really important.
"Whenever you go anywhere and say you are from Te Ranga people say that's the pig and possum hunt schools."
He says there has been an increase in professionalism in recent years and that, plus the school's experience of running the event, means other schools contact him asking if they can use it as a template to run their own pig and possum hunt.
