Cutmore surfed to a 6.53 point ride on his last wave in the final minute to snatch victory from Gebert, himself leapfrogging Piper-Healion with his last ride of a 5.63.
It is a return to form for Cutmore and Gebert who suffered earlier than expected defeats at the National Championships. However, it is the second successive final for Piper-Healion. Mount Maunganui surfer and day-one standout Luke Griffin finished fourth in the final.
Manu Scott-Arrieta (Sandy Bay) was another returning to the winner's circle after a long stint winning the Under 20 Boys' Division. Scott-Arrieta eventually made easy work of the final surfing to a 12.63-point heat total to defeat Sam Sands (Chch) in second, Jacob Warnes (Mount) in third and Eli Voschezang (Auck) in fourth.
A pair of titles went to Whangarei after Billie Scott won her Under 20 Girls' Division. Scott's final was highlighted by a nice right-hand runner that shaped up nicely for her to post a 7.5 point ride. Scott finished ahead of Indica Ratima (Rag) in second, Maaia Reid-Bennett (Mount) in third and Lily Robertson (Te Aroha) in fourth.
Gisborne's Finn Vette won the Under 16 Boys' Division, his first win after competing in the Billabong Grom Series for several years. Surfing up a division, the 13-year-old goofy foot surfer defeated national champion Kora Cooper (Rag) by less than a point in the final after posting the highest single wave score of 7.67 out of a possible 10 points. Tom Robinson (Whangarei) finished in third ahead of Finn Johnson (Gis) in fourth.
Australian Charlie Phillips continued her good form day one to claim the Under 16 Girls' Division. Phillips led the final from the outset and was only challenged toward the end of the final by national champion Brie Bennett (Rag) who eventually finished runner-up ahead of Georgia Wederell (Mount) in third and Summer Carkeek (Auck) in fourth.
Raglan's Jayden Willoughby and Mount Maunganui's Anna Brock claimed titles in the Under 14 Divisions. Both surfers are first-time winners for the Billabong Grom Series.
Willoughby surfed to a 12-point heat total while Brock won with a total of 6.30.
