Keep New Zealand Beautiful Announces National Litter Audit Results
Enough cigarettes found across New Zealand for 2,142 per person
Keep New Zealand Beautiful (KNZB) has today announced the results of the 2019 National Litter Audit (NLA), the most comprehensive litter audit of its scale ever carried out in New Zealand.
The NLA was developed in consultation with Statistics New Zealand, the Department of Conservation and the Ministry for the Environment with funding from the Waste Minimisation Fund. The audit includes similarities to the Beach Litter methodology developed by these entities to allow for comparability and standardised monitoring across domains. Over 80% of the litter and pollution found in our oceans and waterways comes from land, with the United Nations estimating that there are 46,000 pieces of plastic in every square mile of the ocean. The importance of this audit for both land and sea litter management is immense.
Keep New Zealand Beautiful is an iconic not-for-profit charitable organisation that has been leading the way in educating New Zealanders on how to ‘Do The Right Thing’ since 1967. For 52 years they’ve been at the forefront of the litter abatement movement in New Zealand. As New Zealand’s population and tourism has grown, so has the litter problem. KNZB are committed to innovation in sustainability to combat litter and continue to serve as leaders in the environmental sector.
Heather Saunderson, KNZB CEO says, “For the first time, New Zealanders now know exactly how much rubbish we are accumulating and what that rubbish actually is. As we looked at count, weight and volume, some of the results are on par with international studies. However, there are some surprises as well, such as the volume of disposable nappies littered across New Zealand. Enough to fill 158 Olympic size swimming pools! So, there’s much work still to be done.”
KNZB undertook the audit from February to July and compiled data through the physical inspection and visual counting of litter in a number of specific, fixed sites. The audit covered quantities, types, locations and brands of litter disposed across the country.
“As you can imagine it has been a huge undertaking but a critical one for New Zealand. Now we have a benchmark and can use future audits as a tool to track our progress. Our G.J. Gardner Homes Clean Up Week on 9-15 September is a good example of one of our behavioural change campaigns that KNZB runs across the country, changing the landscape of New Zealand through educating, inspiring and empowering more New Zealanders, to keep New Zealand clean. From the research it’s clear that Clean Up Week is more important than ever and we’d encourage businesses, schools, marae and community groups to sign up here and get involved.”
A minimum of five areas per local authority were audited, across a mix of site types; public recreational spaces, car parks, industrial, residential and retail sites, as well as a mix of railways and highways. More than 40 sites in the Auckland region were monitored to account for the size of the population.
The NLA addresses the land-based litter problem by providing Tier 1 statistics and baseline data on litter across New Zealand to help inform local and national policy development and will provide the basis for ongoing environmental reporting on litter.
Executive director of Packaging New Zealand, Sharon Humphreys, says the National Litter Audit opens up a new level of conversation between institutions in New Zealand. “The work done by Keep New Zealand Beautiful not only gives us a baseline to measure future initiatives from, but allows us to draw a line in the sand and respond as a collective to hard facts. This is the litter situation in New Zealand as it is at the moment; the question is, what can we do as a nation to improve it?”
The cumulative results from the research and initiatives reported in this summary provide a foundation for the next generation of litter prevention activities. Keep New Zealand Beautiful are focussed on education, behaviour change and working with leaders of industry who are committed to sustainability. To this end, Keep New Zealand Beautiful have partnered with DB Breweries whose mission it is to ‘brew a better New Zealand’. Further details of this partnership will be released in due course.
The next audit will be crucial, says Saunderson, to fully understand the litter flux. “To truly understand and combat New Zealand’s litter issue, we will need to revisit these sites within three years’ time. Changes in litter type and the accumulation of litter can be used to assess the effectiveness of management strategies, identify sources and activities leading to the production of land (and subsequently waterway) litter and to determine threats to our ecosystem.”
