Meanwhile, in the men's grade, Tauranga's latest professional squash player, and top seed, Ben Grindrod took out the men's title against third seed Max Trimble - winning in three sets.
Trimble, however, made it to the final after a close five set battle with his training partner and mentor Brent Lewis.
Devoy's sons Josh and Jamie Oakley were both playing in the men's open division with Josh, who is currently vying for selection into the New Zealand Junior Boys team along with Trimble, finished fourth.
Josh, who was seeded fifth, played Northland's Lewis for in the third and fourth play-off.
The division 1 men's final was a tense battle between Dargaville's Aaron Randall and Dean Williams from Cambridge, with Randall winning in an exciting five-setter.
The prize-giving was followed by a highly-anticipated $500 cash draw sponsored by Angus.kiwi.nz, which was won by 10-year-old Devlin Gurr of Mid-Western.
Organisers felt it was a successful event, citing the tournament attracted 97 entries from all over Northland, Auckland, Waikato, Bay of Plenty and one from Australia.
