About AgriSea
New Zealand's leading producer of sustainable seaweed-based solutions
for agriculture, horticulture, and personal care
Science, Technology & Global Leadership
AgriSea is New Zealand's largest investor in seaweed biostimulant research and one of the country's most advanced developers of biological and nutritional farming inputs.
We work in long-term partnerships with leading research organisations including the University of Auckland, University of Waikato, Lincoln University, AgResearch and The Bioscience Economy Institute. This research is supported by the Ministry for Primary Industries, Callaghan Innovation and the Agricultural and Marketing Research and Development Trust, ensuring our products are grounded in robust, independent science.
Our proprietary fermentation extraction technology allows us to consistently unlock high-value bioactive compounds at commercial scale – delivering repeatable, reliable performance across soil, plant and animal applications.
AgriSea technology is now licensed internationally, enabling our global partners to produce advanced biostimulants, hybrid fertilisers and animal feed additives using our proven processes.
Designed for Commercial Farming Systems
AgriSea's supply chain is fully integrated. We oversee everything from raw material sourcing through to formulation and production. Our Paeroa manufacturing site operates as a living laboratory, giving us complete control over quality, consistency and scalability.
AgriSea products are trusted by leading farmers, growers and government-owned Pāmu farms, and are exported globally. Many of our customers are recognised industry leaders who demand measurable results, season after season.
Sustainability at AgriSea is embedded into our product design to reduce environmental impact and support regenerative farming systems.
Pushing the Boundaries of Biology
In addition to our core agricultural products, AgriSea is extracting value from our seaweed resources for future-focused biotechnology. We hold exclusive global IP for a high-performance nanocellulose hydrogel developed from our seaweed waste streams, with applications in agriculture, healthcare and advanced materials.
Across everything we do, our purpose remains clear: to combine our values, world-class science and practical innovation to deliver biological and nutritional solutions that help farmers and growers win – now, and for generations to come.
