Teams will be male, female and mixed, with a highlight likely to be the five-kilometre six-place mixed “sprint”.
Organisers are drawn from the two city waka ama clubs, Mareikura and Horouta.
One of the organisers, Vesna Radonich, said the event would not only help the development of junior and new paddlers, it would be a good hit-out for crews preparing for the long-distance nationals off Ahuriri and Napier in mid-October.
Out-of-town paddlers and supporters would be welcome, she said.
Organisers envisaged the event encouraging people to visit Gisborne for watersports.
The historical significance of the bay and district rivers, along with the abundance of clubs and people active in watersports, gave the event tourism potential.
The event would also showcase paddling to the Gisborne community.
If conditions suited racing along the shoreline, spectators could watch the action from the beach.
If racing was along city rivers, the riverbanks offered plenty of vantage points.
Ten races are planned for the day.
