To change behaviour around littering, Keep New Zealand Beautiful recognises the need to understand the mechanics of how and why people litter. This is why, in 2017, Keep New Zealand Beautiful commissioned Sunshine Yates Consulting on the National Litter Behaviour Study.
Fieldwork in New Zealand covered areas from the greater Auckland region, from Orewa to Pukekohe, as well as the Wellington region, including Porirua and Lower Hutt, in the North Island and Canterbury, including Christchurch, Rangiora, Oxford and Akaroa in the South Island.
The methodology includes the use of observations of people disposing of items of litter, and surveys with members of the public, some of whom were observed disposing of items. The methodology is focused on the behaviour of New Zealanders in public places, such as shopping streets, parks, transport hubs, public buildings, public squares, markets, waterfronts and beaches.
The report was published in April 2018 and is available for viewing here.
