New Zealand food scraps collections: how they work and what goes in

Food makes up roughly a third of what the average New Zealand household sends to landfill — and in a landfill it rots without oxygen, releasing methane. That's why councils across the country are adding a small food scraps bin to the kerbside line-up: Auckland rolled its service out from 2023, and councils from Tauranga to Christchurch either run one or are phasing one in. If a 23-litre green bin has just appeared at your place, here's how to get the best from it.

How the collection works

The setup is the same almost everywhere: a small kitchen caddy for the bench or under the sink, and a larger kerbside bin that goes out weekly alongside your rubbish and recycling. Collected scraps go to commercial composting or anaerobic digestion facilities, where they're turned into compost and, in some plants, renewable energy. Because it's weekly and takes the wet, smelly material out of your rubbish bag, most households find their red-lid bin shrinks dramatically — some councils have moved general rubbish to fortnightly as a result.

What goes in

• Fruit and vegetable scraps, peelings and cores
• Cooked and raw meat, fish, shellfish and small bones
• Bread, baking, rice and pasta
• Dairy, eggs and eggshells
• Coffee grounds and tea bags (loose leaves always; bags — check your council, as plastic-mesh bags are often excluded)
• Leftovers and plate scrapings

Unlike a home compost heap, the commercial process handles cooked food, meat, dairy and small bones without attracting vermin — so don't hold back the Sunday roast leftovers.

What stays out

• Compostable packaging and coffee cups — most NZ facilities can't process them; they go in the rubbish unless your council explicitly lists them.
• Liquids and cooking oil — drain them; liquids leak and smell.
• Garden waste — grass clippings and prunings belong in a green waste bin or home compost, not the food bin.
• Pet poo and kitty litter — rubbish bin, always.
• Plastic bags and bin liners — only use the compostable liners your council approves; anything else contaminates the load.

Keeping it fresh through summer

A warm Kiwi summer will test any caddy. Line it (council-approved compostable liners, or newspaper where allowed), tie bags off before they're heavy, and keep both lids clipped shut — the kerbside bin's handle locks the lid against wind and curious wildlife. Put the bin out every week even when it's not full, sprinkle in some baking soda if smells build, and give the caddy a hot soapy rinse at each empty. Freezing meat and fish scraps until collection day is the veteran move for hot weeks.

One more tip: the kitchen caddy only works if it's easier than the rubbish bin. Keep it next to where you chop, not under the sink behind the cleaning sprays — two seconds of friction is the difference between a habit that sticks and a caddy that sits empty.

Weekly food scraps, fortnightly recycling, maybe fortnightly rubbish too — the roster is getting harder to hold in your head. BinMinder sends a free reminder the evening before each collection, matched to your address, so every bin makes it to the kerb on time.
