AgriSea

What AgriSea does

AgriSea is a M\u0101ori-owned, intergenerational family business founded in 1996 and headquartered in Paeroa, New Zealand, that develops and manufactures seaweed-based biostimulants, hybrid nutrient solutions, and animal nutrition supplements. The company processes New Zealand native brown kelp (Ecklonia radiata), fish hydrolysate, and other organic inputs through a proprietary cold-brewing fermentation technology that operates without heat, chemicals, freezing, or dehydration, preserving natural hormones, amino acids, micronutrients, and bioactive compounds (polysaccharides, phlorotannins, mannitols, betaines). Each batch is fully traceable to source. Auxiliary technologies include a zeolite-based slow-release carrier (sourced from the Rotorua/Taup\u014d volcanic region) used in Soil+ and Combo+, and a terrestrial-plant-extract blend combined with seaweed in Fortress+ Dairy.

The product portfolio spans 12 commercial SKUs plus the Ocean Organics consumer sub-brand: animal nutrition (Animal Nutrition, Fortress+ Dairy, Equine Nutrition, Animal+, Seaweed Salt Blocks), soil and pasture (Soil Nutrition, Ocean Nutrition, Soil+, Combo+, Pasture Nutrition), plant foliar (Foliar Nutrition), apiculture (Bee Nutrition), and consumer skincare, herbal tea, and home garden products under Ocean Organics. AgriSea serves dairy, drystock (sheep, beef, deer, alpaca), horticulture (kiwifruit, avocado), viticulture, apiculture, equine, turf, lifestyle block, and home garden segments. The company sells through a hybrid model of direct e-commerce (agrisea.co.nz), field sales via Area Field Consultants who perform on-farm soil and herbage testing, exclusive turf distribution through PGG WrightsonTurf, and four Australian retail partners for bee products. Pricing is unit-based across size tiers (1L-1,000L liquids; 20-500kg solids) with tiered freight, and products carry BioGro Organic, B Corp, FernMark, and NZ Made certifications.

Documented peer-reviewed and customer outcomes include an 18.5% lift in pre-weaning lamb weight gain (Lincoln University), 29% lift in calf weight gain, 17% lower somatic cell counts across 1,357 dairy cows, 49% reduction in kiwifruit coolstorage pitting, 80% lift in hive brood production, up to 123% lift in honey yield, a NZ$3,000/ha higher orchard gate return on kiwifruit, 50% fertiliser reduction, and NZ$50,000/year fertiliser savings on a 260ha dairy farm over six years. The company holds research partnerships with Lincoln University, Scion, University of Auckland, University of Waikato, AgResearch, Plant & Food Research, ECO Soils Research, and the Bioscience Economy Institute, and has won the 2020 National Fieldays Innovation Award, 2021 NZ Science Awards Partnership Award (with Scion), 2022 NZ Hi-Tech Awards M\u0101ori Company of the Year, and 2025 NZIBA Excellence in Sustainability award.
