Fairlie won with a 9.86 total to Emerre-Ryan’s 8.34, with Demi Roberts (Mount Maunganui) third on 7.53 on a countback from Emma Ryan (Mangawhai).
“It is so epic,” Fairlie said. “I had a hard year last year but have come into this year trusting that I have what it takes to do well, so yeah, I am happy to win.
“All of the big names were out of the final and all the groms were in there and it was good to be surfing with them all and vying for the title.”
Gisborne’s Dylan Barnfield was second to national champion Jaxon Willows (Mount Maunganui) in the open men’s final.
Barnfield was second in his heat, but won his semi-final with a 15.17 score, eliminating fellow Gisborne surfer Daniel Procter (third, 11.84) in the process.
Willows, who did the open/under-18 double at the national championships in Gisborne, repeated that effort in Papamoa.
The 17-year-old won the open men’s final with 14.67, heading off Barnfield (12.84), local Matt Cockayne (11.90) and Auckland’s Matt Newdick (10.44).
Willows also won the U18 boys’ final with the highest score of the event - 17.66, including a 9.33 wave.
