About Agrisea New Zealand

AgriSea NZ Ltd is a multi-award winning sustainable New Zealand company, family owned and operated. The company produces Seaweed Soil, Foliar, Turf, Pasture and Animal Health concentrates for Agriculture and Horticulture.

The New Zealand native seaweed species (ecklonia radiata) is batch-brewed with specially selected essential herbs for up to 90 days. The natural brewing process eliminates the use of processing with heat, chemicals, freezing or dehydration that might ‘denature’ the sensitive nutrient balance, allowing the natural growth stimulants and micro-nutrients to be released in an active form to enhance soil and plant health. AgriSea’s natural brewing methods are unique for commercial production.

AgriSea continues to develop its export relationships with a number of international interests. In many cases our contacts in Europe, USA and Korea have used seaweed based fertilizers for many years and consequently have a high level of knowledge and confidence with these products. The export section of the business is expected to provide healthy growth for the Company over the next few years.

Research into the benefits of seaweed has been more advanced internationally than in New Zealand, as seaweed products have been used internationally for generations. AgriSea would like to provide research that is specific to NZ seaweed. AgriSea is committed to funding ongoing research trials in NZ to establish accurate data relating to the efficacy of its products.

An American Scientist - Mr Douglas Murray conducted trials near Chicago on AgriSea's Foliar Nutrient compared with equivalent products from the US which had to be used at 10 times the rate to get the same results as the AgriSea product.


"Scientists overseas are interested in New Zealand seaweeds because they produce higher levels of sulphates and other compounds that generally make molecules more reactive".
Dr Jenny Smith, Marine Scientist, Cawthron Institute - Nelson NZ"


The major difference between Seaweed and chemically manufactured mineral sources is that artificial minerals can be 'locked up' in the soil and not efficiently utilised by plants and/or animals. Unfortunately, the deficiency of one trace mineral may not always be corrected by the simple addition of this one micronutrient. The lack of one trace element may in fact be attributed to an excess of another. For example excess copper and zinc reduce iron availability. On pasture, an excess of molybdenum produces a copper deficiency. It is therefore sensible to provide a balanced micronutrient package contained in seaweed, rather than a single element."
