Surf Life Saving New Zealand sport manager Mike Lord said it had been several years since Surf Life Saving ran a provincial competition like this.
"Today's challenges were about reinstating a high performance event that offers athletes a shot at national representation at the pinnacle event- the World Lifesaving Championships. We got to see some really high level racing as around 240 athletes tested themselves against the best of the best. Athletes are always proud to represent their club but representing your region adds another level of responsibility and they gave it their all," Lord said. "We look forward to seeing this event grow in the coming years."
