New Zealand criticized for weak ocean protection efforts

Despite being the guardian of one of the world’s largest marine territories, New Zealand has been called out by scientists and conservationists for failing to adequately protect its ocean ecosystems.

While its exclusive economic zone (EEZ) spans more than 4 million square kilometers, roughly 15 times the size of the country’s landmass, less than 1% of this vast marine area is fully protected from destructive activities.

Marine ecologists warn that key habitats are still vulnerable to commercial fishing methods such as bottom trawling, which can severely damage deep-sea ecosystems. Conservationists argue that the government has not followed through on long-standing proposals, including the long-delayed Kermadec Ocean Sanctuary, which would have protected 620,000 square kilometers in the South Pacific.


Internationally, New Zealand has promoted itself as a leader in sustainability and environmental stewardship. However, experts say its domestic marine policies do not align with that reputation. While other nations have significantly expanded no-take marine reserves in recent years, New Zealand has lagged behind.

Scientists emphasize that the global health of the oceans depends on nations like New Zealand stepping up. The country’s waters contain rare and fragile ecosystems, many of which remain poorly understood. Experts are urging the government to take decisive action, by expanding marine protected areas, banning bottom trawling in ecologically sensitive zones, and aligning domestic policy with global conservation goals.

Failure to act, they warn, risks not only biodiversity loss but also New Zealand’s standing as a responsible ocean steward.
