"So after consultation with the Mt Maunganui Surf Club and Bay of Plenty Harbour Authorities, we've decided to move to the protected waters of Pilot Bay on the Tauranga side of Mount Maunganui," he said.
Despite the change of course, none of the races will be shortened, including the main race, which remains 2.6km long.
This will be the second time in the event's history the contingency course will have been used due to conditions. The first time was in 2011.
A huge line-up of 1100 swimmers will line up in tomorrow's races, including a strong field of elite swimmers in the main race, including former world 5km open water champion Melissa Gorman, other Australians George O'Brien and Rhys Mainstone and New Zealand number one Kane Radford, all of whom have won races in this year's series.
New race start times as follows:
'I'm Going Long' 2.6km - 10.30am start (briefing 10.10am at Pilot Bay)
'Step it Up' 1000m - 12.15pm start (briefing 12.10pm at Pilot Bay)
'Give it a Go' 300m - 12.55pm start (briefing 12.50pm at Pilot Bay)
State OceanKids 200m - (1pm at Pilot Bay)
