With more natural fibre than any other disposable nappy on the market, it is vital that you are fitting our groundbreaking eco nappies as they were designed.

A huge reduction in plastic means you need to get accurate about where you adhere the tabs – and keep them straight!

Please note that our incredible eco nappies run a little large, especially for newborns. If the size you’ve selected isn’t a snug fit at first, try us again as your bub gains weight in a couple of weeks.

Our boxes of nappies are now available in split sizes, so you can transition up the size chart more smoothly.
Make sure our mighty eco nappies stay put!
Watch our demonstration on how to align our tabs and frontal tape so your nappies stay put. You won't believe how strong our grip is when the tabs are secured correctly!
What size? And how many?
Our nappy size guide acts as a recommendation as only you know your child the best. As a guide our nappies should fit around your child easily, but not meet in the middle - the nappy should be a snug fit when tabs are secured. It is important that the tabs be fixed straight along the frontal tape to hold the nappy in place. Nappy Pants should pull up in place, and fit snuggly, but not so tight as to leave a mark on the skin. We recommend going up (or down) a size to ensure the fit is in line with these guidelines.

Our size guide has been developed around children whose size & weight is in the 50% and above, according to the World Health Organisation (WHO) also in your Red PCHR Book.
What makes our nappies the best?
It's our unique Plantcell Technology™ that makes the Ecoriginals absorbent core the best. It holds over 900ml of liquid, which is drawn away from the skin, so it stays dry and rash free. Happy bums = happy mums!

Our 3 most common queries

How I dispose of Ecoriginals 90% biodegradable Nappies? 

For our nappies to biodegrade in the fastest possible time, we rely on you to dispose of your Ecoriginals nappies without enclosing them in plastic. We offer biodegradable bin liners with our subscriptions and as a one-time order, and these are a perfect way to dispose of our nappies, so that they can decompose in your local waste management. Or wrapping them in newspaper or our nappy packaging is another great alternative if you’ve run out of our corn starch bags.

Where are Ecoriginals nappies made?  

We have built a relationship with a manufacturer located in New Zealand, whose plant is powered entirely by renewable resources and this is where all of our wipes are made. Our nappies include premium and responsibly sourced materials from the United States, China and Japan. These materials are then consolidated and shipped to our NZ partner's facility in China, with a view to bring all of our production to New Zealand shores very soon.
