In 2016, over 190,000 tonnes of litter was collected from the streets of New Zealand by approximately 86,000 Keep New Zealand Beautiful volunteers. Motivated by this and with the support of the New Zealand Government, Keep New Zealand Beautiful carried out a National Litter Audit (NLA) in 2019 which compiled data through the physical inspection and visual counting of litter in a number of specific, fixed sites.
The information collected provides data on the quantities, types, locations, and brands of litter deposited across the country.
The NLA was developed in consultation with Statistics New Zealand, the Department of Conservation and the Ministry for the Environment. It will help to address the land based litter problem by providing Tier 1 statistics and baseline data on litter across New Zealand to help inform policy development, and will provide the basis for ongoing environmental reporting on litter.
