New Zealand Owned & Operated

AgriSea New Zealand is an award winning, family owned seaweed company at the forefront of the biostimulant industry in NZ – we are the single biggest investor in research for the seaweed sector and have been helping farmers and growers for over 25 years.

Years ago, husband and wife, Jill Bradley and Keith Atwood went on a woofers holiday around organic farms of New Zealand. They discovered the true, rich tastes of organic fruit and veges and committed to growing organically for their family. They were also introduced to the effectiveness of seaweed on the health of soil, plants and animals.

This began their journey producing organic products for your garden and well-being and biostimulants for a complete biological and sustainable food production system.

Why AgriSea


Promoting The Mana And Mauri Of Soil

Rere Ki Uta, Rere Ki Tai is a collaborative research project that aims to build more resilient, profitable and healthy farms for our whenua and te taiao (land and environment), whānau (families) and farming communities across Aotearoa New Zealand.

Together, our collective of Māori, conventional and organic kaimahi pāmu (farmers) and researchers is sharing our knowledge, experience, and science to test ideas at the forefront of soil management. We want to know whether farming in ways that honour the mana and mauri of soil might be better for everyone, and if so, how to do it.

Our goal is to reignite hope and pride in farming in Aotearoa, honouring the Te Tiriti o Waitangi partnership between Māori and Pākeha to help restore and strengthen connections between the people who eat food and those who grow it, and between farmers and the whenua (soil) they love.

This research project is funded for two years by Our Land and Water National Science Challenge as part of the Revitalise Te Taiao research programme and is hosted by AgriSea.

What our customers say

Lynn Samuels

Larnach Castle, Dunedin

When we started off, the cattle were getting lice and I don’t get any of that now. They’re big and fat, I don’t feed them in winter but let them fossick and help themselves to what they need. Their health has improved enormously.

Miah & Jenny

Smith Dairy Farm, Atiamuri

“We really wanted to test it. There was no gap in pasture production after three years, and the AgriSea paddocks came in at half the cost. There is more available N in our AgriSea paddocks, where clover is actually fixing nitrogen, than the paddocks that had N fertiliser put on.”


Vilagrad Vineyard, Waikato​

“You could see the difference in the vines and the leaves in particular. The leaves went from a yellow colour to a very dark green. They were shiny and looked healthier.”
