Five new marine protected areas have been established off the southeastern coast of New Zealand's South Island. They officially came into effect on July 1, 2026, and cover a total of 308 square kilometers of the coastal waters of the Otago region. This represents about 4% of the region's entire coastal marine territory.
The new network has been named Te Au Roa o Te Rakihouia. It was chosen jointly by the New Zealand Department of Conservation and representatives of the indigenous Māori people — Kāi Tahu. The protected areas represent the first major expansion of fully protected marine territories off the country's mainland in over a decade.
Several unique marine ecosystems are now under protection: kelp forests, rocky reefs, sandy seabed areas, underwater canyons, and fragile deep-sea coral communities. Such places serve as shelter, feeding grounds, and breeding areas for a multitude of marine animals.
The new protected areas are particularly important for yellow-eyed penguins, New Zealand sea lions, Hector's dolphins, and albatrosses. These animals use the waters off the coast of Otago for foraging, resting, and raising their young. A significant portion of their habitat now has the strictest conservation status.
Marine protected areas in New Zealand operate on the principle of 'you can look, but you can't take'. Swimming, diving, snorkeling, and boating are permitted here, but fishing, collecting shellfish, damaging kelp, or otherwise disturbing the natural environment is prohibited. Essentially, these are true national parks, just underwater.
The creation of these protected areas is especially crucial for kelp forests. These underwater groves provide food and shelter for fish, crustaceans, mollusks, and young marine animals. They also mitigate wave impacts and help maintain the stability of the coastal ecosystem.
Authorities expect that the absence of fishing will allow marine life to gradually recover. In these protected zones, animals will be able to breed freely, and scientists will be able to observe how ecosystems develop without constant human interference.
The new protected areas have increased the area of fully protected marine territories off mainland New Zealand by almost 50%. For a country renowned for its unique nature, this marks one of the most significant conservation achievements in recent years.
This story serves as a reminder: ocean conservation begins with creating places where marine life can exist according to its own laws. Now, corals, underwater forests, dolphins, sea lions, and penguins have significantly more such space.
