Scott finished well ahead of the field, in a time of 1 hour 59 minutes 47.54 seconds. Next came David Boles in 2:00:22.82 and Sebastien Priscott in 2:03:06.31.
The open 10km women’s race was much closer, with Stefannie Gillespie (Zenith, Dunedin) taking the win by 0.34 of a second from Kate Dryden (Australia) in a sprint finish.
Gillespie and Dryden pulled away from Mia Pugh (Greerton, Tauranga) and Maiana Flament (New Caledonia) to battle it out stroke for stroke in the final 100 metres.
The female championships were blown wide open by defending champion Charlotte Webby’s late scratching.
Gillespie finished with a time of 2:11:59.22, with Dryden (2:11:59.56) and Pugh (2:12:08.85) taking home the silver and bronze medals.
Gillespie decided not to swim the 5km race to try to conserve her energy.
“I go to Adelaide in a couple of weeks for the Australian Open Water Championships and I learned a lesson last year when I swam both events here and didn’t have anything left in Australia.”
The 5km men’s championship race also came down to the wire with Scott out-touching 2016 champion Boles.
Scott finished with a time of 59:56.86, Boles was second in 59:57.17 and Quinton Hurley was third in 59:57.93.
The New Zealand Championship was the first step for Scott, who hopes to qualify for the Pan Pacific Swimming Championships this year. Scott will also head to the Australia champs, which is also a Pan Pacific qualifier.
The women’s 5km championship race was tight, with 15-year-old Maiana Flament from New Caledonia winning the visitors’ gold medal in 1:05:34.11.
Mia Pugh was the first Kiwi home in 1:05:40.45 to win the NZ championship. The 16-year-old from Bethlehem College in Tauranga also added the NZ Secondary School Open Water 5km and 10km titles to a successful weekend.
The New Zealand Open Water Championships form part of the annual Epic Swim which has attracted over 900 swimmers competing in a range of open water swims from 100m for children to the 17.5km event.
