About Us
Green Waste Products NZ is an early-stage Māori cleantech company on a mission to transform gorse, one of Aotearoa’s most invasive weeds, into sustainable, bioplastics products. Our current focus is to unlock the potential of gorse oil for innovative cosmeceutical applications.
Based in Te Tai Tokerau (Northland), our kaupapa is grounded in circular economy principles, whenua regeneration, building strong community partnerships and creating meaningful pathways.
Aotearoa is home to over 25,000 exotic plant species, with hundreds threatening our native ecosystems. Gorse alone covers around 1.7 million acres and spreading. We work alongside local Māori, businesses, and organisations to create a more resilient future by quite literally turning gorse into gold.
The world's first gorse-based bioplastic golf tee prototypes
It's been 3.5 years in the making but finally we've got some gorsome news to share. Introducing to you the world's first gorse-based bioplastic golf tees, made from a blend that contains 30% gorse and a natural agri-based polymer.
A big thank you to my friends, family, funders, partners and gorsome humans for all the insights, encouragement and support.
We're on a mission to turn more of this green waste into gold.
2025 Tupu Accelerator Journey
What an incredible evening at the Auckland Art Gallery to close out our 8-week Tupu Accelerator Programme — https://tupu.org.nz/.
Huge thanks to Tapuwae Roa, Sprout Agritech, and Callaghan Innovation for creating a platform where Māori innovators can unlock potential, chase dreams, and drive meaningful impact.
We were fortunate to have an outstanding delivery team led by Te Puoho, Aunty Saara, James, Brittany, and Ian, along with inspiring guest speakers who shared real-world experiences and practical solutions.
Lastly, a special mihi to my fellow cohort members — you made this journey richer, more inspiring, and truly memorable.
