Aucklanders could have their food and garden waste picked up from the kerb as the region seeks to minimise rubbish under the new super-city.
A report to the Auckland Transition Agency says the new council should consider adding an organic bin to its weekly collections.
The Auckland region sends 1.4 million tonnes of rubbish to landfills every year, including one third which is organic.
A separate green waste collection has never been attempted.
The Waste Minimisation Act requires the region to reduce its rubbish by one-fifth by 2015. However, a report by PricewaterhouseCoopers says that is going to be a struggle under the present system.
Under the super-city, seven different rubbish systems will have to be brought together, meaning big changes for many residents.
The report says rubbish should stay under direct control of the council rather than be given to a separate council-owned company.
However, a waste management company owner on Waiheke Island says the idea to create a separate green waste collection for Auckland homes is crazy and residents should deal with it themselves.
John Stansfield says a campaign on the island has reduced the amount of green waste going to landfills by half and the super-council should encourage composting for the rest of Auckland.
