The Tauranga Girls' College Year 10 student was also the underdog in her final, up against Emmalee Morrell, 17, who is regarded as the club's top women's player.
But Jodae, who plays off a seven, upset the predictions with a 5&3 win.
"I just went out and played not worrying, whereas Emmalee went out thinking she was not going to lose," Jodae said. "It was crazy. I just played my best game ever, I think, in the second round, when I shot even par for 15 holes."
Jodae lost the junior girl's final to Olivia Choo the day after her senior triumph, with fatigue setting in after BOP junior golf commitments meant she played 13 rounds in seven days.
Tauranga Golf Fusion pro Rob Ilott says Byron and Jodae winning did not surprise him.
"Their work ethic and how nothing fazes them too much makes the difference. They like the challenge and are mentally tough," Ilott said. "It is going to become more common. Kids want it now with Lydia Ko and Danny Lee leading the way and I think it will get younger and younger."
