The Watercare Harbour Clean-Up Trust oversees the removal of litter from Auckland's Waitemata Harbour, Manukau Harbour and inner gulf islands, and promotes the concept of rubbish-free waterways.
Sponsored by Watercare, the trust has two contractors who crew the Phil Warren boat. They work year round to scoop up bottles, plastic wrappers, tyres and other litter from the harbour. They also clean along the shorelines and beaches as well as in estuaries and mangrove areas using kayaks or a flat-bottomed punt.
Since the Watercare Harbour Clean-Up Trust’s launch in 2002, 3,672,338 litres of rubbish have been removed from Auckland's harbours and the Gulf Islands. This equates to nearly 30 million individual pieces of litter.
In the first three months of this year, the trust and its volunteers collected 110,255 litres of litter.
