Bay of Plenty surfers James Ririnui and Jonas Tawharu have taken out their respective divisions at the latest rounds of the Billabong Grom Series in Whangamata.

It was James' first win at a national level winning the Under-14 Boys' Division. He was the third different winner from three events this year proving the division is packed full of talent.

The youngster defeated national champion Thomas Robinson (Whangarei) after he rode to a 6.27 point ride with five minutes to go putting him in to the lead. James managed to hold Thomas off for the remainder of the heat.

Jack Lee (Whakatane) finished in third place surfing in his first final of the year and Taylor O'Leary (Mur) finished in fourth.

As for Jonas, he managed to surf his way to a second straight win in the series in the Under-17 Boys' Division but not before he was pushed until the final hooter by local surfer Dylan Preston.

The powerful surfer posted a 13.5 point heat total compared to the smaller Dylan who finished with 13.2 points.

Dylan's final wave fell short of the 6.3 points required when he completed an air reverse on the inside section for a 5.87.

Dylan surfed to his best result of the year, in finishing runner-up while Caleb Cutmore (Hamilton) placed third with Jared Gebert (Ohope) finished in fourth place.

Some of the other Bay surfers to feature strongly at the weekend was Raiha Ensor who finished a sold second in the Under-17 Girls' Division behind Gisborne's Kai Woolf.

Kai bounced back from a third at the first event of the series to post a comprehensive heat win.

She put the blow torch on her opponents when she surfed to a nine point ride midway through the heat to take the lead.

She finished with a 15.33 point heat total and an easy victory.

Winner of the first event of the series, Raiha finished runner-up after being the form surfer of the division, edging out Elin Tawharu (Mount) who finished in third place and Maaia Reid – Bennett (Mount) in fourth.

In the other divisions, Dune Kennings won the premier Under-20 Boys' Division alongside Gabriella Sansom (Albany) who won the Under-20 Girls' Division.

The surf deteriorated for the second day of the event with a small swell under 1m and moderate onshore winds all day.

Dune finished with a 14.43 point heat total to win the final beating Taylor Hutchison who surfed to his second runner up finish of the three event series.

Hutchison finished with an 11.77 point heat total to defeat Harrison Whiteside who is fresh back from competing in Australia on the World Qualifying Series.

Finishing fourth was first-time finalist in the Under 20 Men's Division, Matt McGregor (Whangarei).

Gabriella backed up her win at the first event of the series with a win at Whangamata.

She was locked in a close battle with all finalists and held down second place for the part of the final before her sister Bianca was deemed to interfere with another surfer and was deducted half of her second scoring wave relegating her from first to second.

Gabriella then took advantage of the situation increasing her lead and surfing to an 11.33 point heat total for the win.

Despite being at a disadvantage with the interference, Bianca managed to place second in the final ahead of Claudia Fraser (Piha) in third and Abby Falwasser – Logan in fourth.

Stella Smith repeated the dose in the Under-14 Girls' Division winning her second straight event of the Billabong Grom Series.

Stella looked aggressive in her approach going for big turns ultimately finishing with a 10.93 point heat total.

Christchurch surfer Estalla Hungerford finished runner up ahead of Mount's Georgia Wederell in third.

The Billabong Grom Series presented by Oceanbridge comprises three events at Mount Maunganui, Whangmata and Piha. The Piha event takes place on March 5 and 6.
