We’re restoring blue ecosystems.
Welcome to Sea Nest.
Restore degraded ecosystems
Sea Nest enables restoration of degraded blue ecosystems by providing eco-engineered substrate that mimics natural habitat.
Regenerate mahinga kai
Sea Nest products provide suitable surfaces and niches for mahinga kai species such as kelp, pāua, mussels, oysters, fish, octopus, and crayfish.
Cultivate marine species
Sea Nest is propagating target marine species (including Macrocystis kelp) to accelerate restoration and enable cultivation for commercial aquaculture.
Support sustainable aquaculture
Sea Nest supports aquaculture by enabling the cultivation and ‘bottom mounting’ of multiple species, delivering biodiversity benefits, and eliminating or reducing adverse effects.
Provide eco-friendly coastal protection
Sea Nest products are suitable for the construction of eco-engineered artificial reefs - delivering positive coastal protection and biodiversity outcomes.
Adapt to climate change
Sea Nest is investigating the potential for artificial reefs and active restoration of marine environments to play a role in climate mitigation and adaptation.
What’s new about Sea Nest modules?
They’re sustainable. Sea Nest modules are made from eco-friendly concrete, and produced using overpours - i.e., concrete that would otherwise go to waste.
They’re low cost, scalable, and for all of NZ. Our modules are affordable, and easy to transport and deploy anywhere in NZ. Production by McGregor Concrete means we can easily scale up production, making marine restoration viable at a small and large scale.
They’re designed for NZ. Our modules are designed for temperate environments. They provide nursery habitat, refuge and substrate to support a wide range of species.
