ISBN 978-0-473-49359-2 2 | Keep New Zealand Beautiful 2019 National Litter Audit MESSAGE FROM THE ASSOCIATE MINISTER FOR THE ENVIRONMENT New Zealand prides itself on its reputation as being “clean and green”. Ensuring that reality matches the image we need major shifts in the way we care for the land and waters of Aotearoa, and the climate, to reduce the impacts of human activities. We need nature to sustain us and we need to connect with and restore nature. Research for Keep New Zealand Beautiful has found that 99% of New Zealanders believe it is crucial for our country to maintain its clean, green image, with 93% believing it is very important not to litter. We need to do much more to reduce waste and work is happening here. It is heartening to learn that 84% of waste that could become litter is dealt with appropriately, by being put in the bin (preferably a recycling bin if it can be recycled). That still leaves 16% that isn’t. In tonnage terms, this is significant. And it represents an unacceptable amount of litter pollution that ends up in nature, including in rivers and streams and the ocean. We can and must do much better. Shifting to more sustainable practices requires changes in behaviour. Central and local government need to make this easy but individual actions around what products to use and consume, and what happens to our stuff at the end of its life, make a big difference. Funded through the Government’s Waste Minimisation Fund, this report is one of various initiatives underway to better manage litter in New Zealand. These projects are providing better data, helping to raise awareness about the impacts of litter, and encouraging people to refrain from littering. Better data helps identify the policy changes that will be the most effective and where investment is required. This report also gives us a baseline dataset to monitor litter into the future. It helps us shift to a circular economy, where we focus on designing out waste and pollution, keeping products and materials in use longer, and restoring and being restored by nature. This Keep New Zealand Beautiful report helps fill an important gap in our knowledge around litter to ensure our “clean green” image is a reality.
