Tauranga Girls' College are back to defend their under-19 girls' title in a tough grade with former champions Hamilton Girls' and Feilding also in the hunt to retake their former title.
The addition of an under-19 girls' development grade to the tournament for the first time is a reflection of the growth in girls' rugby nationally.
Tournament director Ian Parata said the tournament was a great one and would be the start of an Olympic journey for some players.
"I am again looking forward to running this tournament," he said. "The talent that we will have on display will be fantastic to watch and to see the growth in these young athletes skill set will provide plenty of excitement for spectators. We are confident this tournament will continue to be a high quality experience for all involved.
"We look forward to sharing this experience with the players and parents at the International Stadium. Having finals on a Saturday makes this a real whanau event with our future talent doing their best to take home the medals."
The sevens action is from 10am to 5pm on Friday and Saturday.
