Greenshields said part of the initiative was to educate young people on the importance of the dune system.
"It's important because they are the next generation.
"The eco-systems [the dunes] support here are massive. We wouldn't have our roads. We wouldn't be able to live so near the beach if we didn't have a healthy dune system."
Coast Care was a partnership between five coastal district and city councils and the Department of Conservation.
Over the past 25 years, volunteers and schoolchildren have helped to plant more than a million native plants along the New Zealand coastline.
