Shout out to Dale and Caspian for auditing the litter from our recent Petone Beach Clean Up🌊Thanks to the recent storms, it was a big one!

In just a 100m x 10m survey area, Wellington locals collected 1,899 pieces of rubbish — and of that total 1,896 of them were plastic.

The most common items found were:
🥡 Food wrappers: 1,088
🧴 Bottle caps: 522

That means the majority of rubbish washing up on the Petone foreshore is single-use plastic.

What’s even more alarming is the increase since the last survey:
Food wrappers jumped from 56 to 1,088, and bottle caps from 22 to 522.

This data shows how the way we use and dispose of plastic is directly impacting our coastlines and moana. The good news is that we all have the power to do something about it!

Next time you’re at the beach, take a moment to pick up three pieces of rubbish. And next time you’re at the shop, swap one item for a sustainable alternative. Small actions add up 💙

Our friends at Spirit of Adventure Trust have spots available on their upcoming winter sailings, which look truly life changing! If you know a 16–19 year old in your life that wants to push themselves, build confidence, and make lifelong connections, nominate them here! https://form.jotform.com/260966877159881

Even better, thanks to our mutual partnership with Aon New Zealand the Spirit crew and Sustainable Coastlines are collaborating to bring Litter Intelligence to every epic voyage.

Last weekend the people of Wellington showed up to clean up Petone foreshore. 🏖️

Every month we run a Litter Intelligence survey at this site – and sadly this has been our biggest one yet. The recent storm in Wellington brought a large amount of rubbish to the survey site. Luckily we had 46 awesome volunteers who came down and removed 94kgs/ 760 litres of rubbish from the beach. Results from the audit coming soon so stay tuned!

A massive thank you to all the volunteers who came along up to help protect our beautiful moana 🌊

There's so much about nature we're only beginning to understand. Clean-ups and litter data collection matter — not just for dolphins and seabirds but also for the tiny creatures who make a bigger difference to our ecosystems than we realise 🪱

Analysis: Some estimates suggest there may be more than 170 trillion pieces of microplastics in the world's oceans today.
