"Yeah, I was kinda shaking a little bit and I was like 'oh no' when he got that last ride," said Butler in reference to Whiteside's last wave.
"I am just happy to win again, I had fun at Whanga, I always do, and I am looking forward to Piha 'cause there are always waves there too. I want to finish the series with another good result."
Whiteside finished the final in second place which was a vast improvement on his semifinal finish at the first event. Isaac Kettle (Taranaki) placed third in the final which was one better than the first event of the series while Callum Chuter (Mount) made his first final at this level of competition and finished fourth.
The under-16 girls final was the closest of the day with the lead swinging several times before Jasmine Smith (Gisborne) zeroed in on her second straight win in the series. Smith finished with a 10.50 point heat total, her last two waves scoring 4.9 and 5.63.
"This is my last Billabong Grom Series event ever so I wanted to win so bad. It was one of my goals to win two events this year because I can't make the final event," said Smith who will be absent from event three at Mount Maunganui - it clashes with the Surf Lifesaving Nationals.
The second of two wins for local surfer Tane Bowden came in the under-14 boys division. Butler finished the final in second place on 11.40 points.
Tane Bowden (Whangamata) claimed his first of two wins in the under-12 boys with a massive 15.90 points. Bowden had no mercy on his less-experienced opponents as he warmed up for his big under-14 boys final match up. Luke Griffin (Mount) came second in the final ahead of James Ririnui (Mount) in third.
