In the other Division 1 semifinal Te Whare Kura o Mauao host Bethlehem College, who won their spot by points differential.
Te Whare Kura o Mauao remain the only unbeaten team this round having won the Te Kani Shield and the 1st round Dick Little John Trophy with a 29-17 win over Western Heights last week.
In Division 2 Taupo Nui a Tia have had a disrupted run to the semifinals with two defaulted games, so the Taupo boys may be a little rusty when they host Otumoetai College.
The travel factor will make the job a harder task for Otumoetai College. Taupo Nui a Tia have been unbeaten throughout the competition so it will be a tough ask for the Paul Braddock coached team.
In the other Division 2 semifinal Te Puke High School face the other Taupo team, Tauhara College, who will be seeking revenge for a 27-3 loss in round four.
Tauhara College were outgunned in that match and will need to lift their game to topple the second best team in the division.
The Division 3 title will be decided this weekend when Mount Maunganui College take on the U15A team from Rotorua Boys' High School.
This will be the Mount Maunganui boys' last home game and with a sniff of the title it should be the best game of the round.
