His preparation for ISA Worlds has included running and surfing as much as he can, as well as researching waves in Ecuador. "I've been told it's like surfing Manu Bay in Raglan, a left-hand point break," he said.
His goal is to at least get through to the quarter-finals of the event, and he thinks the New Zealand team have a good chance. In 2013 the Kiwi team placed ninth at the event when it was held in Nicaragua.
"The surfing's good - we just don't get the support that the other countries get."
The trip is expected to cost around $5000 to $6000, and Scott-Arrieta is selling raffle tickets and appealing for donations to help him get there.
Scott-Arrieta's ultimate goal in surfing is to "try and make a living out of it". Donations can be made into Scott-Arrieta's fundraising account 12-3099-0765129-51.
The Junior Championships is an annual event having been held since 2003.
