On average it costs $212 per tonne or $1000 per truck to send non-recyclable items to landfills and this cost is passed on to ratepayers around the country.
Southgate says: "One way we can all get involved is to rinse your recycling so it's clean before it goes into your recycling bin. Get the whole family or household into it and make it a habitual task – just remember rinse, recycle, repeat, it's easy and takes no time at all."
WasteMINZ Sector Projects Manager Sarah Pritchett says landfill was a needless end for potentially recyclable materials.
"We can do better. We really want to encourage people to give rinsing their recycling a go and to realise that it's not that hard. Their effort will reduce our waste to landfills significantly, so their actions have a huge positive flow-on effect."
The competition runs until November 5 and is part of a wider WasteMINZ campaign funded by the Ministry for the Environment aiming to change behaviour when it comes to recycling practices.
