Unlocking seaweed's potential

Greenwave Aotearoa is cultivating a world-leading regenerative seaweed industry from Aotearoa New Zealand. We grow macroalgae to restore marine ecosystems, support coastal livelihoods, and unlock new value in product innovation across agriculture, health, beauty, and beyond.

With a focus on science, partnership, and Te Ao Māori, we’re building a vertically integrated, impact-led enterprise that transforms seaweed into high-value solutions for our planet, our people, and our pets.

Our vision

A thriving Blue Economy that regenerates ecosystems and creates lasting cultural, social, and economic value.

Our mission

To unlock the full potential of Aotearoa New Zealand’s ocean economy by restoring mauri to our moana (seas), creating lasting regional jobs, and delivering measurable ecological, cultural, and economic outcomes at scale.

The core focuses
Indigenous Partnership & Cultural Integration
Co-designed governance with iwi and hapū ensures Te Ao Māori values shape our strategy, sites, and supply chain. Our work is aligned with the UN Sustainable Development Goals (SDGs) and global movement toward nature-based solutions.
Circular Economy & Climate Action
Products that replace synthetics, reduce emissions, and drive sustainable design from the ocean up using cutting edge R&D and proprietary technologies to unlock the potential of Aotearoa’s unique macroalgae species.
Marine Ecosystem Regeneration
We restore biodiversity and enhance water quality, backed by peer-reviewed science and ecosystem monitoring. We measure success not just by revenue, but by what we regenerate.
People & Place-Based Development
Regional bioprocessing hubs, training pathways for rangatahi Māori, and scalable job creation in coastal communities.

Why seaweed?

Seaweed is a climate-positive solution with untapped potential.

It absorbs carbon, restores biodiversity, and improves water quality—while serving as a powerful input for bio-based products across five high-growth sectors:

• Agricultural Health – regenerative biostimulants to restore soil and reduce chemical inputs

• Pet Health – natural supplements for vitality, immunity, and wellness

• Human Health – nutraceuticals backed by science and traceability

• Beauty & Personal Care – clean, clinically active cosmeceuticals

• Macroalgae Innovation – sustainable ingredients for future-focused industries
