Quinn could not find the right waves in the final. With time running out, he started to go for broke to bridge the gap but fell on crucial waves, finishing with a two-wave score of 13.57.
Raglan’s Luke Hughes, who shapes Stairmand’s boards, finished second with a two-wave score of 16.40 after leading early in the 30-minute final.
Dunedin surfer JC Susan, the only goofy-footer in the final, was fourth with a heat total of 8.17.
Stairmand heads to Hawaii in the next two weeks to start his international campaign at the Volcom Pipe Masters, so the national title comes as a timely confidence boost.
“To have my name on that trophy with all those amazing surfers like Al Byrne, Wayne Parkes, Iain Buchanan, and Maz and Jay Quinn is crazy,” Stairmand said.
In the women’s division, former world junior champion Ella Williams, of Whangamata, won her first open title.
“I have dreamed of getting that title since I was seven years old,” said Williams, who won the final with a two-wave total of 13.5.
She will now try to qualify for the World Tour, with her focus on the first event of the year, at Burleigh Heads in Australia at the start of February.
National champs host club South Coast Boardriders Association claimed the club championship from defending champions Bay Boardriders of Mt Maunganui.
Mt Maunganui surfer Kea Smith, 15, was second in the women’s final. She contested three finals and was runner-up in each of them.
Third was Mt Maunganui’s Elin Tawharu, who won the women’s under-18 and u16 divisions, and fourth was Auckland’s Bianca Sansom.
Raglan’s Daniel Kereopa contested more heats than anyone else during the week and on the final day. He ended with four runner-up finishes — in the over-28 and over-35 divisions, men’s longboard and men’s stand-up paddleboard.
Vehicle breakdown thwarted the national championship hopes of Gisborne over-60s surfers John Gisby and Ross Moodie.
