"It was hard swimming in a wetsuit too. It's a bit tight when you're not used to it so I need to get in a couple more swims before the next event [in the State Ocean Swim Series] in Mount Maunganui," he said.

Stefannie Gillespie (Dunedin) was a convincing winner in the women's event. Gillespie was vying with national 5km open water champion Penelope Hayes for the title with around 500m to go, but a burst of speed saw her claim a comfortable 21 second advantage at the line.
The series heads to Mount Maunganui next month.
