Not all laundry detergents are made equal. Some clean your clothes exceptionally, while others leave stains. Some are poisonous to aquatic life and some are just freaking expensive.

As a content creator, I am asked to trial many things and receive all sorts of lovely gifts. Earlier this year I looked at my laundry shelf and realised how many eco-friendly laundry detergents I had tested. It was only natural for me to write a blog post to review them here to help you on your hunt for the best washing power in NZ.

I’ve spent my spare time reviewing 6 eco-friendly laundry detergents. Time well spent? I’m hoping that my efforts help you find an eco-friendly laundry detergent that suits you.

Each detergent reviewed below is:

• Available in Aotearoa New Zealand

• Cruelty Free

• Made in Aotearoa New Zealand or Australia (mostly handmade in small batches)

All detergents have varying price points and are better for the planet and people. I have tested these eco-friendly laundry detergents by using them in our weekly washing loads. We are a childless couple with a muddy dog - just so you know what testing they have gone through.

Before I jump into my riveting review, here are some basic ways to improve your sustainable-laundry-game:

1. Wash at 30 degrees celsius or below. Why? It’s estimated that only 10% of the energy used to power a washing machine is used to power the motor. 90% is used to heat the water!

2. Use a Cora Ball or Guppy Friend to collect micro plastics that shed from your synthetic clothes when washed (use code ETHICALLYKATE for 5% off the ones at CaliWoods) or look into investing in a microplastics filter - learn more about microplastics in your washing here.

3. Spot wash + air dry + don’t wash your clothes just because you have worn them. Why? Being thrown around in a washing machine adds to wear and tear. The less it happens, the longer a garment will last.

4. Use metal pegs. Mine are from Bento Ninja (code ETHICALLYKATE for 10% off) - the dog chews the wooden ones and the plastic ones are a no-go for obvious reasons.

5. Line dry. Why? Dryers use energy, take up space, and cost money. If you must use a dryer, use woollen dryer balls. These dry your clothes faster, therefore using less energy. They will also break down in your home compost at the end of their life.

6. Wash full loads, never half loads, or just that one shirt. That’s such a waste!

7. A front loader uses less power and less detergent than a top loader (if you can, opt for a front loading machine).

8. Read the care label and follow it.

Eco warehouse SoapNut Shells

13c/wash ~ soap nut form ~ purchase online ~ produced in India ~ home compostable packaging ~

SoapNuts are a foreign concept to most of us. They were to me! How they work: “The shells of these fruits contain a natural substance called Saponin. Once released into water, they create mild suds similar to soap and will effectively remove dirt and oils from clothes and garments.”

I pop 7 soap nuts into a little cotton bag, and throw it in the wash. The SoapNuts can be used 3-4 times before you need to put them in the compost and fill the little bag up again. I dash a few drops of essential oils onto the bag too. Although I had more success with them than other reviews I’ve read, I found myself sub-consciously reaching for the other laundry detergent options over time, especially when I was washing a particularly smelly load. I know some households who absolutely swear by them! Even with kids! Worth a try I reckon, though be warned.

Why would I buy this? I probably wouldn’t, but I’ll keep on trying them.

Veto Washing Powder

25c/wash ~ powder form ~ purchase online ~ made in Aotearoa New Zealand ~ home compostable packaging ~

veto washing powder comes in three scents; rose, lavender, and jasmine. I tried the lavender one and it was great. A standard powder, nothing riveting to report. I would recommend pouring the powder straight into an airtight container, as the paper bag isn’t a great way to store it long term.

Why would I buy this? Incredibly cost effective, subtle smell, range of scent options, cute home compostable packaging.

Happi Earth

25c/wash ~ liquid concentrate form ~ purchase online ~ made in Australia ~ refillable packaging ~

Happi Earth is a different concept to your usual powder or liquid. It’s a concentrate, so no water is being purchased or shipped (this reduces carbon emissions). The pump is metal, and the refill pouches are made from craft paper and lined with plastic. A pouch should last you an entire year, so this is a great option for households who want the easy route. When the pouch is finished, send it back to Happi Earth to sterilise, and refill.

The concept is great, but the execution isn’t quite there. The concentrate sometimes leaks out the side of the pump and gets a little messy. Additionally, sometimes it doesn’t come out and you have to direct it on a particular angle. I also don’t love the colour and texture of the concentrate, but I cannot fault it’s ability to wash my clothes.

Why would I buy this? I probably wouldn’t.

Figgy & Co. Laundry Powder

16c - 41c/wash ~ powder form ~ purchase online ~ made in Aotearoa New Zealand ~ home compostable packaging ~ options for DIY or pre-made ~ detergent free ~

Figgy & Co. have several accessible laundry detergent options. Order the pre-made tubs (41c/wash) or make 7.5kgs of it at once (with the help of Figgy & Co’s ingredients) for 0.16c/wash. I would recommend storing whatever option you choose in an airtight container. If you want the savings, but are skeptical about the DIY aspect, read their helpful blog here that should encourage you to go for it.

I’ve also learnt a lot about detergents from Figgy & Co; their laundry powder is detergent free. Detergent can have negative consequences on aquatic life, so instead, Figgy & Co hand batch their liquid soap which acts as their surfactant and ensures they stick to their values of planet friendly products.

Why would I buy this? Super cheap DIY option, reliable, can change the scent to whatever I want, detergent free.

ecostore Geranium & Orange Laundry Liquid

32c/wash (approximate, depends on what quantity you purchase) ~ liquid form ~ refill stations nation-wide ~ readily available in most supermarkets ~ made in Aotearoa New Zealand ~ take back scheme for all bottles ~

This laundry liquid is a favourite in our household. It’s what we have used for years and continue to use even throughout my detergent trials (because we know it works!). Although it’s the most expensive option out of the 6 I trialled (though this depends on the quantity you purchase), the minimal extra is worth it. The geranium and orange scent is delicious, though you can opt for scent-free too. We fill ours up at GoodFor Store but you can find refill stations all over the country.

Why would I buy this? Refill availability, always cleans the clothes, delicious smell.

Earthwise Laundry Liquid

21c/wash ~ liquid form ~ purchase at most super markets ~ made in Aotearoa New Zealand ~ packaging made from 75% recycled plastic ~

If this wasn’t in plastic, it might be my favourite. It ALWAYS does the job. I trialled the non-scented one, which was disappointing because I love that fresh washing smell, but I see they have other scent options. Earthwise has the ‘Environmental Choice’ tick and has been dermatologically tested - so it might be best for those with sensitive hands too.

Why would I buy this? I wouldn’t - there are many more plastic free options on the market that work well for me.

Eco-friendly Laundry Detergent Q&A

What makes a laundry detergent eco-friendly?

An eco-friendly laundry detergent is formulated with biodegradable ingredients that break down naturally without harming the environment. It avoids harmful chemicals like phosphates, dyes, and artificial fragrances, and often comes in recyclable or compostable packaging. Many eco-friendly detergents are also cruelty-free and made from plant-based or renewable resources. All of the products above are not as ‘sustainable’ as each other. I’ve deliberately listed a range of options so that accessibility of product and personal preferences are considered too.

What is the best eco-friendly laundry detergent?

The best eco-friendly laundry detergent often depends on personal preference and specific needs. It’s ideal to choose a detergent that suits your washing machine type and laundry needs while aligning with your sustainability goals.

Do eco-friendly laundry detergents work as well as regular detergents?

Yes, eco-friendly laundry detergents can be just as effective as regular detergents. They are designed to clean clothes thoroughly while being gentle on the environment. With advancements in formulations, many eco-friendly options are proven to tackle stains and maintain fabric freshness without compromising their green credentials. Often eco-friendly laundry detergents can be even more powerful and reliable than regular detergents.
