That leaves the way open for Matt Scott (Auckland) to retain his so far unbeaten record in the series after he took line honours at Mount Maunganui and Auckland.
Scott also won the 10km Open Water Championship in Lake Taupo last month.
Also in the mix for the Legend of the Lake men's race are a trio of fellow Aucklanders, Phillip Ryan, Jackson Dawson and Sebastien Priscott. Priscott pushed Scott all the way in Taupo, and the pair could well feature in a close finish.
Swim Rotorua's Scott Boles, 16, has also shown up well this season, finishing third in the Sand to Surf and winning the Hinemoa Swim at the same stretch of water as tomorrow's race at the end of January.
In just its second year the Legend of the Lake has proved to be a popular addition to the national series and is also incorporated into the four round local Swim the Lakes Rotorua series.
As well as the 3.5km swim, which starts at 11am, there are 1km (1.45pm), 500m (1.47pm) and 200m (Ocean Kids - 1.30pm) distance swims.
The next round of the Ocean Swim series will be the Christchurch Crown on March 4, while the Swim the Lakes series finishes with the Rotary Rotorua open water swim at Lake Okataina on March 12.
