"Our own chances? We're quietly confident, but respectful of all the other teams. A lot of our boys have already medalled at nationals."
Teams at the championships will compete for national honours in one, six or 12 paddler teams over distances of 250 and 500m.
The tournament is a milestone for John Paul College - students are competing for the first time in a decade, after starting training only six weeks ago.
Teacher Cecelia Pakinga praised the ethos of waka ama and the tournament.
"It's about leadership, broadening the scope of our school and giving opportunities to participate," she said.
John Paul College students Anahera and Claudia, both 13, said they were "nervous" but excited to be be taking part for the first time.
Waka Ama NZ boss Lara Collins said she was pleased the weather had picked up after such a drizzly morning.
For her, holding the championships at Tikitapu was a no-brainer.
"Look at it - it's beautiful."
She said waka ama was a great sport that everyone could get involved in.
"It's fun, anybody can do it. It caters to all kids, and people like getting out on the water and being with their friends."
