The first time some 10 to 12-year-olds ever set foot on the beach is when they arrive on a school trip to help clean up the beach.
Many of the school children who turn up to the annual Love Your Coast Manukau Harbour clean-up event attend schools in South and West Auckland, as well as the Awhitu Peninsula which juts out into the harbour - yet they have never felt the sand between their toes.
Sustainable Coastlines Charitable Trust New Zealand chief executive Sam Judd said at one event he held, three-quarters of the children had not been to the beach.
