World Tuna Day

World Tuna Day History

World Tuna Day is dedicated to recognizing the critical role of tuna in sustainable development, food security, economic opportunity, and livelihoods around the globe. It also serves as an opportunity to spread information, promote global awareness, and acknowledge international cooperation on managing tuna resources sustainably. This global observance has a significant impact, being one of the most widely consumed fish worldwide. It also emphasises the importance of sustainably managing marine resources, which is a shared concern for all nations.

The United Nations General Assembly officially recognised World Tuna Day in 2017, but it had been celebrated informally since 2011. For New Zealand, World Tuna Day holds particular relevance. New Zealand is home to one of the world's largest exclusive economic zones (EEZs), with a vast ocean area rich in marine life including multiple tuna species. New Zealand's commercial fishing industry, local communities, and many individuals depend on this resource. The country is highly invested in sustainable practices and international cooperation to manage regional tuna stocks and ensure their longevity.

In New Zealand, World Tuna Day is recognised by government agencies, fisheries, environmental organisations and the public. They may take part in awareness campaigns, educational programs, and sustainable fishing initiatives. It also includes discussions around the cultural significance of tuna, particularly to Maori communities. World Tuna Day occurs on May 2 each year, serving as a reminder about the importance of sustainable practices to protect the world's tuna stock and to appreciate its value for both current and future generations.

Top 8 Facts for 2026 World Tuna Day in NZ

• The 2026 observance of World Tuna Day centers on the official theme Sustaining Tuna, Sustaining Nations, a call to action established by the Parties to the Nauru Agreement (PNA) to highlight how the long-term stewardship of tuna stocks is directly linked to the economic resilience and food security of Pacific communities.
• For many in Aotearoa, the day carries a unique dual significance because the Māori word tuna refers to freshwater eels, a vital taonga and mahinga kai resource, which often leads to local interest in how international marine conservation efforts compare to the protection of our endemic longfin and shortfin eel species.
• Recent data from the January 2026 Status of the Stocks report reveals a historic milestone for the industry, showing that a record 97% of the global commercial tuna catch now comes from stocks at healthy abundance levels, with nearly 100% of these fisheries no longer experiencing overfishing.
• A major point of interest for the 2025–2026 fishing years is the remarkable recovery of the Pacific Bluefin tuna, which has rebuilt its population so successfully that international management bodies have authorized an 80% increase in commercial catch limits after decades of strict conservation.
• In a significant move for New Zealand consumers, major domestic retailers and brands such as Pams and John West have maintained 100% certification from the Marine Stewardship Council, making the "blue fish tick" a primary focus for Kiwis looking to support sustainable Pacific fisheries at the supermarket.
• New Zealand plays a pivotal role in the global tuna landscape as a member of the Western and Central Pacific Fisheries Commission, an organization headquartered in the Pacific that manages the region responsible for over half of the world’s total tuna harvest.
• Under the Fisheries (Pacific Bluefin Tuna Total Allowable Catch) Notice 2025, New Zealand's commercial limits for this high-value species have been adjusted for the current cycle to reflect the latest scientific assessments and the ongoing health of the Thunnus orientalis population in the wider Pacific.
• National efforts to protect marine biodiversity often overlap with World Tuna Day through the promotion of the Western and Central Pacific Tuna Conservation Pledge, a commitment supported by major New Zealand seafood companies like Sealord to eliminate the use of Fish Aggregating Devices that can lead to unintended bycatch of sharks and sea turtles.
