Kelp Blue


New Zealand’s long history of living in harmony with nature and deep knowledge of the marine environment, together with having the ideal conditions to cultivate giant kelp, make it a clear choice for our second operating location. 

The cold, nutrient rich waters of the South Island have long provided the perfect growing conditions for Macrocystis Pyrifera, also known as giant kelp or bladder kelp. 

Currently in New Zealand, we cultivate locally sourced Macrocystis Pyrifera in our onshore hatchery in Bluff to outplant back to marine farms in Akaroa Harbour. We then trim the top of the kelp forest canopy, leaving the forest to grow and marine life to stay. Through a biorefinery approach, we process the bioactive components into products, starting with a liquid biostimulant for agricultural purposes. Globally, Kelp Blue has a farm in Namibia, an office in Amsterdam, and are setting up operations in Alaska. 


Let’s work together. We are actively seeking input and feedback from the community and stakeholders on our proposal.

To enable this, we are organising a series of hui in Southland, are spending time meeting, engaging, and listening to individuals and different groups. We invite all feedback and will be updating this page regularly with further information so please contact us at We value your feedback, please follow the link to the public consultation survey

Proposed expansion in Southland 

Kelp Blue is proposing to expand our Macrocystis farming into Southland. We have spent time on the water, are sitting with stakeholders, are studying the opportunity, and we are now preparing an application for marine space to farm Macrocystis in the cold, nutrient-rich waters of Foveaux Strait. Please find below a map of the sites we have identified following desk-based analysis and trips out on the water, we are now consulting with different community and commercial groups so we can include their concerns and comments into our final evaluation to choose a site.
