A recent ruling by New Zealand's High Court has highlighted critical gaps in the country's marine conservation efforts, particularly concerning bycatch of protected species like dolphins.
The court found that the Department of Conservation (DoC) had been relying on fisheries laws instead of its own regulations to assess bycatch reports from commercial fishers. This decision raises serious concerns about the management and protection of marine wildlife, including Hector's and Māui dolphins.
Currently, fishing areas can be closed if the bycatch of protected species exceeds set limits. For instance, in Hawaii, no more than 16 leatherback turtles can be caught annually in longline fisheries. If this number is exceeded, the fishing ground is shut down.
Environmental advocates argue that similar measures are necessary for New Zealand's unique marine species, as the absence of strict limits has likely led to higher bycatch rates than necessary.
Justice Cheryl Gwyn's ruling has prompted the DoC to reconsider its policies, emphasizing the need for stronger adherence to conservation laws. The agency has acknowledged the ruling and is currently evaluating its next steps.
As New Zealand faces challenges in marine conservation, this ruling could serve as a catalyst for more effective protection measures for its endangered dolphin populations.
