The Rotorua Girls' High School team has tough competition to retain its crown - with Hamilton Girls' High School, Tauranga Girls' College and Long Bay College also vying for the top spot.
"The Tauranga girls will be ones to watch especially," said Te Aomihi. "They always have a strong team and I remember last year they pushed us all the way.
"For us to win we need to play together well as a team, not as individuals because that just mucks everything up. Our attack is looking very good - we've got some pretty fast players who could open up gaps for us but we need to work on our defence a bit. It needs to be solid to stand any chance."
In total the competition will field 11 under-15 girls' teams and 14 under-19 girls' teams. Five of the girls' teams will compete in the development grade and nine in the open grade.
Rotorua will be represented in the women's under-19 development category by John Paul College. Tauranga Girls' College will be back to defend their under-19 girls' title in a tough grade and former champions Hamilton Girls' and Feilding are also ones to watch.
There are 12 under-15 boys' teams, with five making up the under-15 boys open grade and seven teams forming the under-15 boys' co-ed grade. Title holders Rotorua Boys' High School are not attending.
An added incentive will be the presence of the New Zealand Sevens talent identification team on finals day.
"I'm not trying to think too much about that because it puts me off my game," Te Aomihi admitted. "All I'm thinking about is the game and to try my hardest."
Te Aomihi said she was aiming for a big future in the sport with full backing from her school and family.
"I'm hoping to go very far in this sport because I love it. I want to play for my country. I really look up to Portia Woodman [Silver Ferns Sevens winger]. It would be great to play off her one day."
Carol Holt, the Rotorua Girls' High School sports co-ordinator, added: "Te Aomihi has a great future ahead of her and is a prime example of how we are trying to develop youth here at the school.
"The focus at the moment is developing our youngsters, that's not just individuals but teams, so we have a succession of sides doing well rather than having one-offs.
"It's a big stage for the girls at the stadium but it won't be daunting for them.
"They have put in a lot of work - it's a very different team to last year - so I don't want to say too much about winning but hopefully the result will take care of itself."
