Swimmers using Rotorua lakes are being reminded to stay out of water ski lanes.
The lakes' harbour master and maritime officers have received complaints from water skiers that swimmers are using the designated ski lanes when the lakes are busy, creating problems for skiers.
One complainant who received an infringement notice (fine) for exceeding five knots outside the ski lane had brought a learner wakeboard rider in slowly at a safe place where there were no swimmers, because they had counted 23 swimmers in the ski lane. Later in the day there were more than 40, including small children.
Lakes harbour master Pererika Makiha said the ski lanes were designated to keep both swimmers and skiers safe, and swimmers should stay clear of the designated lanes. However, signage designating the ski lane was often obscured by vehicles and gazebos.
"Skiing from shore is only permitted within the designated ski access lane or reserved ski area," he said.
