The Expo is organised by the Tauranga Marine Industry Association and chairman Brian Kent says punters will be able to wander through the site, which is located right on the Tauranga Harbour.
"Showcasing the beautiful Tauranga Harbour and having fun on the water is what this Expo is all about," he says. "We encourage people to take the opportunity for a free jet-ski rides and to try out the paddleboards and kayaks; a ride in the amphibious Sealegs craft is a real treat."
The Bath Tub Boys will run scheduled races and there will be demonstrations from wake boarders and water-skiers.
The Tauranga Yacht Club will be racing just off the harbour's edge.
