After a settlement period the reclamation will be used for carparking. Amour rock for the marina seawall was sourced from Whangārei and barged all the way down the coast direct to Westhaven, rather than trucked, minimising the project’s carbon footprint. “We’re currently working on the Kennedy Point Marina in Waiheke Island. That’s a very large marina project,” says Greg. “At the moment we’re casting big concrete floating breakwater attenuators in Whangārei for that project. “These are the first of their type seen in New Zealand. Each wave attenuator weighs 220 tonne and we cast our first one yesterday. “In total there are twenty-three of them to do. Rather than building a rock breakwater, which you see in a lot of marina’s, Kennedy Point will have a floating attenuator that goes up and down with the tide, keeping the craft safe inside the marina.” “You can buy as many pieces of good plant as you like, but unless you have the right people operating that plant and managing the projects you wont last very long at all.”
