Conservation groups are calling for increased action to protect Hector’s dolphins after a female was killed in a set net off the Kaikōura coast last month, according to data from the Department of Conservation (DOC).
Rising Concerns for Endangered Species
The incident is part of a concerning trend: DOC figures show 14 of the 24 reported dolphin deaths along New Zealand’s coastline over the past two years occurred in the Canterbury region, with four specifically in Kaikōura. The Hector’s dolphin, the smallest dolphin species, is found only in New Zealand and is currently classified as Endangered.
The primary causes of death reported to DOC were entanglement in set nets (seven cases), bycatch (two cases), beachcasting (three cases), stranding (one case) and finding a dolphin floating at sea (one case). With an estimated total population of 15,700, conservationists argue that even a small number of deaths can significantly impact the species’ recovery.
Calls for Stronger Protections
Conservationists are advocating for more effective enforcement of existing regulations, an expansion of current set-net bans, and enhanced protections for marine areas and reserves. Forest & Bird Canterbury / West Coast regional conservation manager Nicky Snoyink stated that these dolphin deaths are “avoidable.”
Kaikōura Wildlife Centre Trust manager Sabrina Luecht emphasized the importance of “effective marine habitat protection, responsible fishing and accountability” to ensure the long-term survival of these “precious taonga.” Greenpeace oceans campaigner Juan Parada has called for a ban on trawling in dolphin habitats and the implementation of cameras on all fishing vessels.
Currently, set net closures are in effect off Pegasus Bay, the Canterbury Bight, Banks Peninsula, and Kaikōura. Fisheries New Zealand is working with commercial fishing boats to reduce bycatch and is utilizing on-board cameras as part of these efforts.
Frequently Asked Questions
What is being done to protect Hector’s dolphins?
Set net closures are enforced off Pegasus Bay, the Canterbury Bight, Banks Peninsula and Kaikōura. Fisheries New Zealand is as well working with commercial fishing boats to improve bycatch mitigation and the use of on-board cameras.
What are the main threats to Hector’s dolphins?
According to DOC data, the main threats include entanglement in set nets, bycatch, beachcasting, stranding, and being found floating at sea.
What is the current population estimate for Hector’s dolphins?
The endangered species has an estimated population of 15,700.
As coastal management plans are reviewed, will current protections be enough to safeguard the future of this uniquely New Zealand species?
