With a runner up finish, Stewart jumps to second on the national rankings behind new front-runner Taylor Hutchison from Raglan, who finished seventh at the event this weekend.
Stewart said he felt good the whole weekend but was unable to find a final wave to secure a high score, with Quinn finishing the final with a 14.5 and Stewart with 13.75.
"My main kind of goal was just to get the win on the weekend."
However, having secured a second-place spot on the national rankings so early in the season doesn't hurt, he says.
Stewart has looked up to Quinn for 12 years and says when he saw his and other big surfing names on the draw he was excited for a tough competition.
"I don't really look at the draw but I saw all the names and thought it should be a tough weekend."
In the Women's Open division, Whangamata surfer Ella Williams won the title, with Pāpāmoa's Raiha Ensor coming in second. Taranaki surfers Michael Grendon and Jo Moore claimed titles in the longboard divisions.
Stewart leaves for Australia's Boomerang Beach today to compete in the World Qualifying Series between February 20-24. Ensor left New Zealand on Monday for the same competition, where Williams is also competing.
Other local surfers at this week's series includes Tiana-Breeze De Mooij, Elin Tawharu and Kehu Butler.
The 2019 edition of the Barrett Homes Surf Open included Open Men's and Women's Divisions and Men's and Women's Longboard. It was the second of seven events on the New Zealand Surf Series and New Zealand Longboard Tour.
