Kiwanis secretary Leigh Baker is recommending a splash and dash in the clear waters of Lake Rotoma to celebrate Waitangi Day.
He said it was a way for locals to make the most of the natural beauty of the area, as well as having fun and exercising.
"A swim for Waitangi Day makes people aware of the resource we have and maybe we should care for it and look after the ecology of the local area," he said.
The Lake Rotoma Swim has been run annually on Waitangi Day since 1979 and started with just a couple of families wanting to meet up for a regular activity on the day.
Since then the swim has blossomed to a fun day out for more than 100 people and the day has more than 20 entry options for swimmers of all ages and abilities.
