"We just have to take the momentum from the last couple of games and use it to our advantage.
"In this competition anything can happen but we will stay composed and stick to a structured game plan."
There are three more rounds left in the competition after this weekend with the two top teams playing off for the Super 8 Shield on August 13.
Rotorua Boys' High are in the best possible position after wins over Tauranga Boys' College and Gisborne Boys' High School.
Buckton said the side were aiming to win the title after losing in the final last year to Hamilton Boys' High.
"We certainly want to get our hands on the trophy again," he said.
"Beating Hamilton was a big result for us and we have to use that confidence against Hastings.
"A lot is at stake so the boys have to keep focused and put in a solid team display."
- Kick-off at the Rotorua Boys' High School No 1 field at 12pm.
