"The growth in participants has been quite phenomenal really and I think the secret to its popularity is that waka ama is quite simple for kids to take up. The atmosphere at all our race meets is electric. The paddlers are all very competitive but everyone definitely has a lot of fun, too," Collins said.
Six paddlers work as a team over varied distances from 500m and 1500m to the marathon races of 30km to 75km.
The ama, or outrigger, on the left-hand side balances the waka, helping it speed through the water with each stroke of the paddlers.
In Rotorua, the schools will compete for national honours in teams with one, six or 12 paddlers over distances of 250m to 500m.
