Northland surfer Manu Scott-Arrieta has gone back-to-back with his second straight win in the Billabong Grom Series presented by Oceanbridge on Sunday, taking a comfortable ratings lead in the process.

The second of three events in the series was held at Whangamata in messy 1.0m – 1.5m waves, with the Coromandel Peninsula coastline blanketed by low cloud and rain.

Conditions were far from ideal for a summer event but New Zealand's top junior surfers battled it out across eight divisions to secure titles.

Scott-Arrieta won the first event held at Mount Maunganui two weeks ago and today he rode to a 12.0 point heat total in the final to defeated Waihi Beach surfer Zac Curle.

He will now head into the final event of the series at Piha in two weeks looking to close out the series with one more good result.

Placing third in the final was Whangarei's Jamahl Moselen who finished ahead of Wellington's Henry Gautrey in fourth. New Zealand Women's Champion Raiha Ensor from Mount Maunganui, returned to the domestic competition today with a win in the Under 20 Girls Division.

The 18 year old made easy work of her final picking up a pair of six point rides midway through the final for a 13.16 point heat total defeating Te Aroha's Lily McDonald who finished second ahead of Whangarei's Billie Scott in third. The Under 18 Divisions were won by New Zealand representative Jared Gebert, from Ohope, and first time-winner Aimee Brown, from Great Barrier.

Gebert's win sees him climb to number one on the rankings while Brown jumps into second place behind Mount Maunganui's Kea Smith, today's runner up and winner of the first event of the series. Australia's Eden Gray finished in third and Tegen Bishop, from Christchurch, in fourth. In the boys final, runner up Lee Ririnui surfed a clutch wave as the hooter sounded and posted a 7.0 point ride to go from fourth to second but brutally falling short of the 7.08 points required for the win.

Ririnui finished ahead of Whangarei's Tom Norton in third and Mount Maunganui's William Van Der Beek in fourth. Raglan surfer Josef Jungwirth ended a seven year journey to the top of the podium winning the Under 16 Boys Division.

Jungwirth has made numerous finals in the age group categories over those seven years but the win eluded him, until today. Jungwirth defeated Kora Cooper, also from Raglan, who had to settle for runner up for the second time in this series.

Whangarei surfer Tom Robinson finished third in the final ahead of Gisborne's Finn Johnson in fourth. Christchurch surfer Estella Hungerford claimed her first national event winning the Under 16 Girls Division.

After a finals berth at the National Championships in January, Hungerford found herself atop the strong field of female surfers in her division with a 10.84 point heat total.

Hungerford defeated Taranaki's Ariana Shewry in second, Raglan's Brie Bennett in third and Mount Maunganui surfer Georgia Wederell in fourth. Raglan surfer Jayden Willoughby ran way with the Under 14 Boys Division for the second event running to claim back-to-back wins in the series.

Willoughby's performance was highlighted by one long right-hander that saw him post an 8.0 point wave score.

Navryn Malone, from Raglan had to settle for second place in the final behind his Raglan counterpart. Finishing in third was Mount Maunganui surfer Harper McBride ahead of Mathias Thompson, from Piha, in fourth. After missing the first event of the series, National Champion and Christchurch surfer Ava Henderson continued her winning way for the year claiming the Under 14 Girls Division from Piha's Liv Haysom.

Event one winner Natasha Gouldsbury, from Taranaki, had to settle for second ahead of Australian surfer Carol Fujino in fourth.
