Swim Rotorua and the Rotary Club of Rotorua have postponed the Lake Okataina Open Water Swim planned for Sunday due to the severe weather forecast over the weekend.
They said rather than risk the safety of the participants and event personnel, a decision has been made to move the event to the end of the month.
The organisers are disappointed but want the experience to be special one.
The swim was the final in the inaugural Swim the Lakes series promoted by Rotorua District Council to encourage visitors and locals to use the lakes for recreational swimming. It was to feature 200m, 400m, 800m, 1500 and 3000m options.
Lake Okataina was a fitting end to the series as it is described by many as one of Rotorua's most beautiful lakes.
