In its 23rd year, event manager Janette Blyth said the Port of Tauranga Half was second only to the New Zealand Ironman in significance on the country's multi-sport scene, attracting the best from New Zealand and Australia.
"It has added status as the official Triathlon New Zealand national championships and a selection event for the world long distance championships," she said.
A team of about 400 volunteers from local sports groups and organisations, who use the event as a fundraising opportunity, will help things run smoothly while five Mount Maunganui St John staff will man two ambulances during the event.
Ms Blyth said the event was unique because it was held in Mount Maunganui in the middle of the summer holidays, providing a great atmosphere for both athletes and the average three-strong support crews they each brought along with them.
"Participants and supporters get to mix the race with holiday time here at the Mount, the race and the area are both iconic in that respect.
"It also has a unique mix, where some of the world's best athletes are on the start line alongside your average person who enjoys keeping active."
