Akaroa seaweed waste turned into food ingredient
A Māori-led collaboration in Akaroa Harbour plans to convert invasive wakame seaweed into an organic food ingredient for local and export markets, with additional applications as plant biostimulants. The project involves Ōnuku Rūnanga, Premium Seas, and Ceres Organics, aiming to create a certified, export-ready product while addressing an environmental issue caused by the invasive seaweed.
What is happening
In Akaroa Harbour, a non-native seaweed called wakame is spreading. A Māori-led partnership—Ōnuku Rūnanga, Premium Seas, and Ceres Organics—plans to turn up to 280 tonnes of this invasive seaweed into a food ingredient that can be sold locally and overseas. The project aims to certify the product as organic and export-ready. Separately, some of the wakame could be used to make seaweed-based biostimulants, products that can help plant and crop health.
Key facts
- Invasive wakame has been found in Akaroa Harbour, prompting management concerns.
- The project is Māori-led and involves collaboration with Premium Seas and Ceres Organics.
- Goal: create an organic, certified food ingredient suitable for export.
- Potential additional uses include seaweed-based biostimulants for agriculture.
Who is affected
Local communities around Akaroa Harbour may benefit from new economic activity if the wakame is sold as a certified product. Farmers and exporters in New Zealand could access new supply for organic ingredients or bio-based agricultural products. The project may also influence environmental management of Akaroa Harbour by turning a waste issue into a valued commodity.
Practical next steps
Key steps include completing organic certification for the wakame product, establishing export channels and regulatory approvals, and validating the supply chain from harvest to processing. If successful, the initiative could expand to other harbours with similar invasive seaweed issues and explore additional uses for seaweed-based products in the food and agriculture sectors.
Limits and questions
Details on harvest methods, long-term economic viability, and environmental safeguards are not provided in the source. It is unclear how the project will address potential risks to native ecosystems, the scale of harvest relative to ecological limits, and how profits will be shared among partners and communities.
