The first of three events in the Billabong Grom Series presented by Oceanbridge was completed in small waves of less than 1m and onshore winds at Tay Street at the weekend.

Andrew battled the final with each surfer in the final locking in one good ride each, but it was Andrew that went to the sky with a clean front-side air reverse for a 5.93 point ride, and a late lead change he held until the final hooter.

'That was my first final ever and my first win,” Andrew says. 'I didn't even know I was in the lead but that air I did felt pretty good so I was stoked about that then when I got to the beach I was told I won, I was pretty happy, ecstatic about it actually.”

Andrew finished with a 12.27 point heat total. Placing runner-up in the final was the 2015 series champion Taylor Hutchison (Raglan).

He had the highest single wave score of the final, a 6.67 point ride but he could not back it up with another good ride.

Mount surfer Callum Chuter placed third in the final with fellow Mount rider Jordan Griffin placing fourth. Gabriella Sansom stole the win in the Under-20 Girls Division after surfing to a 7.17 on her final wave of the final courtesy of three consecutive backhand turns on a clean right-hander.

She finished with a total heat score of 12.33 out of a possible 20 points to take an early lead in the three event series. Piha surfer Claudia Fraser led for three quarters of the final before being eclipsed by Gabriella ending with a 10.47 point heat total and finishing runner up.

Muriwai surfer Britt Kindred finished in third place ahead of Bianca Sansom (Albany) in fourth.

Mount Maunganui surfers proved too good in the Under-17 Divisions, along with Jonas Tawharu and Raiha Ensor taking out their respective divisions.

Jonas was locked in a tight boys final where he edged out Ohope surfer Jared Gebert.

Jared tried valiantly to find the right waves working hard to find connections but came up short against Jonas.

Elliot Brown (Dunedin) who, two weeks ago won the Under-18 Boys national title, had to this week, settle for third place ahead of Caleb Cutmore (Hamilton) in fourth.

Raiha ran away with the win in the girls final using her smooth style and speed in the small conditions to post a 14.0 point heat total.

Like Jonas in the boys, Raiha managed to relegate double national champion Mount's Elin Tawharu to second in the final with Elin edging out Kai Woolfe (Gisborne) who finished third and Mount's Kea Smith in fourth.

Gisborne's Finn Johnson dominated the Under-14 Boys Division final from start to finish finishing with a 14.0 point heat total.

It was Finn's first win at a national level and his surfing all weekend looked sharp with powerful forehand surfing.

Finn beat Muriwai surfer Taylor O'Leary who started the final well but fell short of the pace Finn set ending with a 12.6 point heat total.

Christchurch surfer Myka Black finished in third place ahead of Josef Jungwirth (Raglan) in fourth.

Gisborne took their second title of the day with Stella Smith winning the Under-14 Girls Division.

It was also Stella's first title and indeed her first final ever as she looks to follow in her sister Jasmine's footsteps, Jasmine having already represented New Zealand on several occasions as well as winning numerous Billabong Grom Series events.

Placing second in the final was Georgia Wederell (Mount) with Hannah King (Gisborne) in third and Daizee Rawls (Raglan) in fourth.
