For the younger kids, the Banana Boat OceanKids event is open to children aged 7 to 10 years old and has 100m or 200m options.
The main event includes the 3.5km Round the Lake swim, and the shorter RotoVegas 1000m and 500m distances, plus an Amphibian event.
This sees swimmers tackle a 1.7km swim, then a 3.5km run around the lake before taking the plunge again with a 500m swim leg to finish.
Rice is excited about bringing the swim series back to Rotorua, and with the return of the national series in general with the first event, the Harcourts Cooper & Co Swim the Shore in Auckland on December 12.
"It's been a tough year for everyone and we hope these swims give people something really positive to aim for and, when they have finished, a real sense of satisfaction."
