10 Sustainable NZ Swimwear brands

Updated: Nov 24, 2022

The temperatures are rising and, all of a sudden, days at the beach and by the pool don’t seem too far away!

If you are on the hunt for new togs (swimsuit for those non-NZ readers) and want to make a conscious, sustainable choice (YAY YOU!) then you’ll be happy to hear that NZ has a number of sustainable swimwear brands, some are even made right here in New Zealand.

Until recently, the swimwear industry was completely dependent on materials made from polyester. The exciting news is that there are now eco-friendly swimwear fabrics, which most of the brands in this article are using. The main fabric used for sustainable swimwear is ECONYL®. So, before I launch into the amazing swimwear brands, let’s start with a quick run down of this amazing fabric:

Manufactured in Italy, ECONYL® is made from 100% nylon waste material, including discarded carpets, plastic components and ghost fishing nets that litter our oceans. It is produced within a closed loop, which means it can be recycled infinitely without loss of quality. In other words, ECONYL® can be recycled, recreated and remoulded again and again. It’s recycling and up-cycling taken to epic levels. Amazing stuff.

And now, bring on the brands….


Nisa is an ethical fashion label and social enterprise based in Wellington, New Zealand. They offer a fully-reversible swimwear range to allow you to wear two different colours in the same style. This year's swim collection features three one-pieces, two bikinis, and a rash top, including some higher coverage options for those who want a bit more protection from the sun. The 2022 collection also features gorgeous gingham prints in black and red.

Nisa's mission is to employ women from refugee and migrant backgrounds, who work together to sew all of Nisa's garments in their central Wellington workshop. The workshop is a place to develop work experience, improve English and start a long and fulfilling career in Aotearoa New Zealand. Sustainability is at the core of Nisa's production, so each swimwear garment is made from ECONYLⓇ regenerated nylon and deadstock fabrics.

“Nisa Swim brings beautiful to ethical by using fabric from recycled materials to make swimwear that celebrates and supports women.”

Price-range: Approx $129 (separates) -$249 (one piece)

Fabric: ECONYLⓇ,

Made in: Wellington, New Zealand. Their workshop is open to the public, and has a shop inside.

Packaging: Wrapped in tissue, then sent inside a mailer made from recycled paper.

Other: NISA currently employs seven refugee women, and has the dream to build an alumni of 100 former employees who go on to inspire their own communities.

NISA places huge focus on quality, creating garments that will be worn and loved for a long time.

The thing that sets Emroce apart from all other sustainable swimwear brands in the world is the fact that they cut everything from zero waste patterns and create no fabric waste in their production process.

With normal pattern making between 15% & 40% of the fabric is sent to landfill.

Emroce have been making waves in Italy for years, but the craziness of 2020 has brought founder Emma and her family back to her homeland of NZ - which is exciting news for us Kiwis! Now based in Pāpāmoa, the Emroce zero-waste swimwear collection is designed and made right here in New Zealand with high-quality, recycled Italian fabrics.

"The main aim for our swimwear is to be zero waste and functional with a perfect fit. We don't make anything for pure aesthetics. We don't follow trends. We cut every style back to it's basic necessities. We would never add an extra strap or frill to make the garment prettier. We would only do so, in order to make the garment function better or to use any scrap fabric that would otherwise become waste."

Price-range: $50(separates) - $95(one pieces)

Fabric: ECONYL® Renew prime

Made in: New Zealand.

Packaging: The swimwear is placed in a brown paper parcel and closed with brown paper tape. The cardboard swing tags are attached with 100% cotton twine.

Other: Each style is cut from a tessellating pattern which leaves no waste. Thread off-cuts are used to stuff cushions, they even use recycled paper for their patterns! After 7 years of manufacturing, no fabric waste has ever left the studio. Based on the average fabric waste caused during clothing production they have saved between 150 to 300 meters of fabric from going to landfill. They also offer some young girls' styles and a collection of non-binary / trans-inclusive swimwear.

Aurai fuses owner and designer Natalia’s life in Auckland, New Zealand, with her hometown in Brazil. The designs are simple but eye-catching, always with a point of difference. Not only are her pieces made from recycled materials and ethically created, the materials are also locally sourced to minimise the cost and impact of transportation. One of the NGOs they work with, Paddle for Hope, has also been their inspiration to make most of their pieces mastectomy friendly.

“AURAI is an eco & ethical swimwear brand propped up by an intimate flair with surf and beach culture and deep respect for nature, created by italo-brazilian designer Natalia Bertolo.”

Price-range: $69 (separates) - $149

Fabric: Their materials include ECONYL®. They have also introduced AMNI SOUL ECO®, made from a polyamide with an improved formulation that accelerates biodegradation in the anaerobic environment, common in most landfills. Also, AMNI SOUL ECO® is a yarn developed and produced in Brazil. Both fabrics are OEKO TEX certified, i.e., zero harmful substances are used in their manufacturing.

Made in: Brazil. The swimsuits are carefully handmade at a small family-owned atelier in Natalia’s hometown in southern Brazil, where she locally sources most of the materials.

Packaging: The packaging consists of a reusable compostable pouch or 100% recycled paper pillow box, wrapped in a compostable shipping bag.

Other: In collaboration with Paddle for Hope, they were inspired to convert most of their SS19 collection into mastectomy-friendly designs. There are not many stylish swimwear options in the market for women who have been through a mastectomy. They make annual donations to Paddle for Hope. Almost all the AURAI pieces feature functional design, such as reversible options and customizable ties.

Now AWWA is different to the rest of these brands, their swimsuits are made from spandex/polyester, they are manufactured in China / Sri Lanka… so how come they’ve made this list? For a very good reason. These are period togs. Yup, they can hold a tampon worth of flow. So while the materials may not be recycled, they are preventing single-use period products, which is another great way to be sustainable! Oh, and AWWA is also a carbon positive company doing great things for our planet in NZ and beyond. They have the one bikini design, which you can buy as separates or together ($39.50 each).

And we can't forget the kids! Nature Baby have just released a range of SPF50 ECONYL® swimwear for your little ones. The one-piece is $69.95.

Find the super cute design here.

So there you have it! An amazing selection of trail-blazing brands who are making swimwear sustainable and ethical, right here in little old New Zealand.

A final thought: when it comes to swimwear, like all fashion, let's take it slow. Let's use what we have, consider second hand, or invest in quality garments and classic styles, that will stand the test of time. Look after them, cherish them, love them. In the words of Vivienne Westwood: "Buy less, choose well, make it last."

I want to thank the lovely Kate Hall from Ethically Kate, who wrote an article on this topic a couple of years ago. That article was my starting point for this one, and you can find it here.
