As bearers of a long and vivid musical tradition, we’re committed to leaving the planet a better place for the next generation. Read more below about how we’re bringing this goal to life, or contact us now to book us for your zero waste or carbon-positive event!
We play on instruments that have been lovingly passed from musician to musician. Our instruments have such long lifespans that some of them may even have been played at weddings and social gatherings a couple of centuries ago!
Our music is printed on paper made entirely from recovered materials (like wheat straw and recycled wood).

Travel to events and the Co2 emissions from that are an unavoidable part of our business, so in response each year we choose local environmentally-focused non-profits to support, to the value of our carbon footprint. In 2025 we’re delighted to again be supporting the work of Fair Food, an award-winning food rescue organisation in Tāmaki Makaurau who are on a mission to feed people, not landfill. In the past year, they rescued and redistributed 608,693kg of surplus food, feeding Auckland communities with about 33,445 meals a week, and thus reducing greenhouse gas emissions by 1613 tonnes.
We had the joy of playing for many weddings and events in beautiful outdoor settings this past season so we’re thrilled to be giving back and helping preserve our taiao through supporting Fair Food.

In 2025 we’re supporting the work of EcoMatters, an organisation that supports the community with knowledge and tools to restore nature, grow food, reduce waste, ride and fix bikes and live more sustainably. They also run workshops and provide opportunities for hands-on environmental action in Auckland.

In 2023 we supported the work of Matuku Link, an organisation aiming to protect and restore a critical piece of wetland in Te Henga. Not only is the wetland significant ecologically for native species such as matuku (bittern, their namesake), pekapeka touroa (longtailed bat), tuna (eel) and many native birds and insects, wetlands are better at carbon sequestration than forests and Matuku Link is working consistently to re-vegetate the wetlands with regular plantings from their nursery.
