The 24-year-old earned $40,000 in prize money and, as a result of the victory in long, overhead waves, now leads the Vans Triple Crown of Surfing series ratings.
Zietz shone after 20 minutes of the final against John John Florence, Fred Patacchia of Hawaii and Alejo Muniz of Brazil, having gradually built momentum in the showpiece contest.
Florence briefly threatened to come back with a late charge that included a near-perfect 9.2-point ride with a reverse 360 air, but Zietz was not to be denied as he answered back with a 9.43.
In addition to beating Florence in the final, Zietz also accounted for Sunny Garcia of Hawaii and Julian Wilson of Australia in what was a breakthrough performance from the Kauai surfer.
“Coming into Hawaii I was definitely feeling confident, feeling really confident in my boards,” said Zietz. “And you know, I’ve had a few injuries over the years, and they’re all healed up so I just believed in myself and I’m super stoked.
“I kept my head down and whoever I drew it didn’t matter, I was just in a heat against myself.”
Zietz has a start in the upcoming Vans World Cup at Sunset Beach, and will need to be in contention for the Vans Triple Crown title by its end to surf in the third stage at Pipeline.
