"Netball and basketball teams train on our courts three times a week, and members of the community use our basketball courts every day when the weather is good, so a lot of people are going to benefit if we can raise the $100,000 we need."
The reunion would be preceded by Colour Kaitaia, a 5km run/walk in and around the town while being doused in coloured powder, on October 26, with all proceeds from the $7 entry fee going towards the covered court.
The reunion/celebration itself would include a "massive" auction, special guests, "and of course the best banquet and entertainment".
"Get into it and make a weekend of it — celebrate the Far North, celebrate what is affectionately known as Bundies, celebrate life," Mr Tan said.
"All proceeds will go into our students and our town, and we can only do this as a community."
All events would be accessible via eventbrite.co.nz, search Kaitaia.
