The Wanganui Swim Club received the $350 lion's share, while Gonville School received $200.
"We didn't expect to have anything left over from the reunion, but then again we didn't really have any idea how many would turn up. But really there was no better recipients for the leftover money," Adams and Lowe said.
The Labour Weekend reunion attracted 90 people
and entry money and raffles over the weekend made up the bulk of the reunion funds.
Wanganui Swim Club board member Neil Forlong and coach Andy McLay both welcomed the gift.
"We are just glad the Gonville members decided to think of us - it is especially welcome when the team is travelling to meetings. That can be an expensive business," they said.
