New Zealand King Salmon’s Blue Endeavour project, approved in 2024, is designed for exposed waters in Cook Strait and has a planned capacity of 10,000 tonnes of Chinook salmon.
New Zealand’s aquaculture industry is entering a new phase. For decades, the country’s seafood reputation has been built around premium mussels, oysters and King salmon, but the next chapter could be written much further offshore. The approval of a major open-ocean salmon farm near Rakiura/Stewart Island has turned a long-discussed opportunity into a potentially transformative commercial proposition, while Māori-owned seafood businesses are increasingly positioning themselves to capture more of the value created by aquaculture.
The timing is significant. New Zealand’s aquaculture sector generated about $650 million in export revenue in 2025, while the Government has set an ambitious target of lifting the industry to $3 billion in annual revenue by 2035. The most dramatic development came in August 2026, when the New Zealand Government fast-tracked approval for Ngāi Tahu Seafood Resources’ Hananui Aquaculture Project off Rakiura/Stewart Island. Once fully operational, the project is expected to produce 14,400 tonnes of salmon a year, generate more than NZ$310 million in sales and create an estimated 415 to 480 regional jobs. The Government describes it as the first aquaculture project approved through the Fast-track process.
That figure alone explains why the project matters. A single farm could generate more than $300 million in annual sales, almost matching the scale suggested by the emerging “$300m-plus” salmon opportunity. More importantly, it demonstrates how open-ocean farming could change the economics of New Zealand’s salmon industry.
New Zealand’s geography gives aquaculture an unusual advantage. The country possesses an enormous Exclusive Economic Zone, while its reputation for clean waters and premium food production gives its seafood exporters a strong international proposition. New Zealand Trade and Enterprise identifies more than 4.3 million square kilometres of exclusive economic zone and around 11,000 hectares of open-ocean space already consented for aquaculture. It also sees potential for King salmon production to rise from roughly 15,000 tonnes to more than 70,000 tonnes annually.
Open-ocean farming is not simply about finding more water. It is a response to the physical limitations of traditional coastal farming. New Zealand King Salmon’s Blue Endeavour project, approved in 2024, is designed for exposed waters in Cook Strait and has a planned capacity of 10,000 tonnes of Chinook salmon. The company sees deeper, cooler waters as an important route for future expansion.
Hananui takes that proposition considerably further. Its projected 14,400-tonne output illustrates the scale that could become possible when aquaculture moves beyond the constraints of sheltered farming locations.The commercial prize is particularly attractive because New Zealand specialises in King, or Chinook, salmon rather than competing head-on with the enormous global Atlantic salmon industry. King salmon represents less than 1 per cent of worldwide salmon production, but New Zealand’s premium positioning allows producers to target higher-value markets rather than relying purely on volume.
The Hananui project is commercially important for another reason: it places Maori enterprise at the centre of New Zealand’s next aquaculture expansion. Ngai Tahu has long pursued a stronger role in marine farming. A 2021 Southland aquaculture settlement transferred 16.6 hectares of aquaculture space off the northern coast of Rakiura to Te Runanga o Ngai Tahu, creating a foundation for future marine development. At the time, the iwi said it wanted aquaculture to support regional diversification while reflecting its responsibilities as kaitiaki, or guardians, of the marine environment.
The Hananui approval now gives that ambition a major commercial platform. Yet Maori participation extends well beyond one project. Māori hold approximately 27 per cent of New Zealand’s fishing quota by volume and value, while Maori-owned enterprises have also built substantial positions in aquaculture and seafood processing. Moana New Zealand, for example, describes itself as the country’s largest iwi-owned fisheries company and operates with a long-term approach rooted in Maori ownership and kaitiakitanga. This ownership structure could become one of New Zealand aquaculture’s most distinctive competitive advantages. Global consumers increasingly want to know not only where seafood comes from, but how it is produced, who benefits from it and whether production respects local ecosystems and communities.
Akaroa King Salmon provides another compelling example of Maori participation in premium aquaculture. The company is a New Zealand-owned partnership involving Ngati Porou, Onuku Rūnanga and the founding Bates family. It has been farming King salmon in Akaroa Harbour since 1985 and has developed a vertically integrated operation spanning hatchery, farming and processing. In June 2026, the business received government support to upgrade infrastructure and expand production. The investment is expected to create about 50 jobs over three years, with benefits flowing to iwi partners and surrounding communities. The company has also highlighted annual export earnings of more than $20 million and investment in breeding programmes designed to improve resilience, genetic diversity and temperature tolerance.
That is a useful illustration of where Maori-owned aquaculture can create value: not simply by owning marine assets, but by participating across the production chain, building technical expertise, creating regional employment and developing export-ready brands. A similar direction is emerging in Northland. Muriwhenua Incorporation renewed a 38-hectare coastal consent in 2024 for oyster farming and entered a memorandum of understanding with Moana New Zealand in December 2025 to explore the responsible redevelopment of its aquaculture interests. The partnership aims to combine expertise with local employment and economic development while retaining Maori decision-making over the underlying assets.
The optimism should not obscure the risks. New Zealand’s wider seafood sector is facing softer prices and demand in some markets. The Ministry for Primary Industries expects seafood export revenue to fall 3 per cent to $2.2 billion for the year to June 2026, before recovering modestly in 2026–27. Aquaculture also remains exposed to biological risks, weather, feed costs, infrastructure requirements, logistics and environmental scrutiny. Open-ocean farming introduces another layer of complexity because farms must withstand powerful marine conditions while maintaining fish welfare and operational reliability.
There is also a social licence question. Every expansion of marine farming must balance commercial opportunity with environmental, cultural and community interests. New Zealand’s regulatory system requires new farms to consider environmental, social, economic and cultural effects before gaining resource consent. That is where Māori participation could prove especially significant. Indigenous ownership can bring commercial decision-making closer to communities with longstanding relationships with the moana, while the principles of kaitiakitanga can provide a framework for thinking about marine assets beyond short-term returns.
The Government’s $3 billion aquaculture ambition may ultimately depend on whether New Zealand can move from selling seafood as a commodity to building premium, scalable and globally recognisable businesses.The latest salmon developments suggest that transformation is beginning. Hananui could create more than $310 million in annual sales on its own, while Blue Endeavour provides another pathway for expanding King salmon production. Meanwhile, Maori-owned and Māori-partnered businesses such as Akaroa King Salmon, Moana New Zealand and emerging iwi aquaculture ventures are demonstrating that ownership, cultural values and commercial scale can coexist.
For New Zealand, the opportunity is therefore bigger than a salmon boom. It is about turning the country’s vast marine estate into a higher-value export platform while ensuring that the economic benefits reach the communities whose relationship with the ocean stretches back generations. If the industry can combine open-ocean technology, premium branding, scientific innovation and Māori-led stewardship, aquaculture could become one of Aotearoa’s most intriguing growth stories of the next decade. The $300 million salmon opportunity may not be the destination. It could be the opening chapter.
