Almost 1800 secondary school students will paddle on Tikitapu over the next week.
The Te Wananga o Aotearoa Waka Ama National Seconday School Championships will see students from 118 schools, from Dunedin to Kaiataia, compete at the lake in W12, W6 and W1 divisions.
Event co-ordinator for Te Waiariki Purea Trust Kelley Korau said the event brought people together.
She encouraged members of the public to watch the racing which was taking place from Tuesday to Friday.
"The atmosphere is awesome. The kids are having fun and there's singing and the racing is exciting to see," Korau said.
