Swimming Northland will host its first open-water event in seven years at Kai Iwi Lakes on December 15.
Event director Ross Gillespie said it had been a while since the last event because of difficulties in finding a suitable date in the current crowded swimming calendar.
"As well as offering a beautiful and unique venue, another benefit of holding it at Kai Iwi is that the whole course is visible to onlookers from the shore with one part of the course running only a few metres from the shore," he said.
Gillespie expected good numbers at the event, with some top open water swimmers attending, including Philip Ryan, who has represented New Zealand and Seb Prescott, a promising competitor.
All course information was available on the Swimming Northland Facebook page and website.
