Twenty teams will compete across the men's and women's senior competitions, as well as the women's under 19 divisions in Nuku'alofa.
Secretary of the organising committee, Iliesa Tora, said the event has been in the works for a number of years and was first mooted in 2013 by the late former Fiji and Tonga head coach Eddie Waqa.
"It's something that we hope to grow and the plan next year, already in the pipeline, is for next year to have three tournaments," he said.
