Kiwi households are churning through nearly two billion plastic containers a year with over a third of it by weight ending up in landfill.
New Zealand's unhealthy addiction to plastic has been laid bare in a report that found households also put nearly 100 million plastic drink and milk bottles in their rubbish bins - instead of recycling them.
Waste Management Institute of New Zealand (WasteMINZ), which is behind the in-depth audit of household rubbish and recycling, says poor labelling and confusing rules across regions are largely to blame.
Sorting through kerbside rubbish and recycling bins of 867 New Zealand households from eight areas the report estimated 1.76 billion plastic containers were being disposed of across the country each year - more than metal (767m) and glass (854m) combined.

The report also found 39 per cent - by weight - of household plastic bottles and containers that could be recycled were going to landfill, and 97 million plastic drink and milk bottles went directly into rubbish instead of recycling bins.
Almost 26m plastic containers were likely not recycled by the processor due to a container's plastic shrink sleeve.
Triggers and pumps - such as those on spray bottles - could also often not be recycled.

Researchers also found confusion around the different types of plastic that could be recycled, with just 2600 tonnes of household grocery packaging made from plastics 3, 4, 6, and 7 disposed of via kerbside collections, compared with the estimated 41,300 tonnes of packaging made from plastics 1, 2 and 5.
"Improved labelling, the choice of plastic used when designing packaging, and standardising nationally the plastic packaging accepted for kerbside recycling to make it easier for Kiwis to know what can and can't be recycled - all of these actions can improve our recycling rates," Sood said.
Associate Minister for the Environment Eugenie Sage said the report was a "wake-up call".
"It highlights the value of much better product design so products and their materials can be easily reused or recycled, and the need to reduce what we use, reuse what we can, and recycle properly.
"It's a timely wake-up call for designers, manufacturers, retailers and marketers to shift towards more recyclable and reuseable packaging. There is a strong public demand for this."

Industry group Plastics New Zealand's CEO Rachel Barker said the report showed current recycling rates were not high enough, with just 65 per cent of plastics 1, 2 and 5 recycled.
"Many councils don't collect polypropylene [5] even though there is a strong end market for this material. Increasing the rate of collection would hugely improve the recycling statistics and this valuable material could be reprocessed right here in New Zealand."
There needed to be better education around proper recycling etiquette, with 8m soft drink bottles with liquid in them, and 1.8m "stinky" milk bottles ending up in landfill, Barker said.
Plastics NZ also proposed improved labelling, allowing only natural or light plastic colours, and improved collection and sorting infrastructure.
The audit and report, supported by a $425,000 grant from the Ministry for the Environment over three years, was carried out late last year in partnership with councils in several cities and regional towns across New Zealand.
Sage said combined with the Chief Science Advisor (CSA) Juliet Gerrard's recent report Rethinking Plastics in Aotearoa New Zealand, the audit provided solid information to help inform the Government's work programme to reduce waste.

Following Gerrard's report the Government announced a ban on more single-use plastic items, including meat trays, cups and takeaway food containers - six months after the official plastic bag-ban came into force.
The overall plan also includes:
• A container return scheme for drink bottles and cans.
• Newspapers, magazines, advertising mail and envelopes
• Paper and cardboard packaging
• Egg cartons
Before recycling rinse all containers. Leave lids on all bottles and containers (except on Great Barrier Island: take lids off all bottles and put in your rubbish bag). Containers should be no larger than 4 litres.
What you cannot recycle in Auckland:
• Plastic bags, and other soft plastics. Seek out soft plastic collections across the city.
• Batteries - lithium batteries can explode and have been known to cause fires in recycling trucks.

What the numbers mean
Many thermoplastics have a code on them that identifies the type of plastic they are made from, helping industry readily sort them in recycling facilities.
But territorial authorities differ greatly in what they accept. Auckland Council accepts plastic bottles and containers from all codes 1-7, while others, such as Whangārei District Council, only accept 1 and 2.
