Key Takeaways
- Hector’s dolphins are rarely spotted in the Bay of Islands, with only one confirmed sighting in the past 100 years.
- There are two species of dolphins: Hector’s and Māui, with the latter being a subspecies of the former and found on the west coast of the North Island.
- Both species are protected, with Hector’s dolphins classified as nationally vulnerable and Māui dolphins classified as nationally critical, with only 54 adult individuals remaining.
- The dolphins are social and friendly, but prone to being hit by propellers and boats, so it’s essential to keep a safe distance and respect their habitat.

Introduction to Hector’s and Māui Dolphins
Hector’s and Māui dolphins are two species of dolphins that are native to New Zealand. According to Department of Conservation marine species adviser Kristina Hillock, sightings of these dolphins in the Bay of Islands are extremely rare. In fact, a confirmed sighting of a Hector’s dolphin in Northland would be only the second in 100 years. This highlights the importance of conservation efforts to protect these species and their habitats. Hector’s dolphins were once found along the coast of most of the South Island and parts of the North Island, but their population has declined significantly over the years.
Habitat and Distribution
Today, Hector’s dolphins are classified as nationally vulnerable and are found in different sub-populations around the South Island. They are only occasionally seen around the North Island, making a sighting in the Bay of Islands a significant event. The Māui dolphin, on the other hand, is a subspecies of the Hector’s dolphin and is found on the west coast of the North Island, mainly between Taranaki and Kaipara Harbour. The Māui dolphin is estimated to have a population of only 54 adult individuals, making it a critically endangered species. The decline of these species is a concern, and conservation efforts are necessary to protect their habitats and prevent further decline.
Identification and Characteristics
Both Hector’s and Māui dolphins are grey and white, with black markings and a distinctive black rounded fin, shaped like Mickey Mouse’s ear. While they are not easily distinguished from each other without DNA testing, they are readily identifiable from other dolphins. The dolphins’ social and friendly nature makes them prone to interacting with boats and people, increasing the risk of accidents and harm. It is essential to exercise caution and respect their habitat when encountering these dolphins. People who spot the dolphin are encouraged to report the sighting to the Department of Conservation, which can help in monitoring and protecting the species.
Conservation and Protection
The Department of Conservation is working to protect and conserve Hector’s and Māui dolphins. The public is encouraged to report any sightings, which can help in monitoring the species and preventing harm. However, it is crucial to keep a safe distance from the dolphins and respect their habitat. According to Zaeschmar, people who spot the dolphin should try to keep their distance and be boat-wise when around the animal. The dolphins are prone to being hit by propellers and boats, which can be fatal. By reporting sightings and exercising caution, the public can play a significant role in protecting these species and their habitats.
Conclusion and Call to Action
In conclusion, the sighting of a Hector’s or Māui dolphin in the Bay of Islands is a significant event, highlighting the importance of conservation efforts to protect these species. The public is encouraged to report any sightings and exercise caution when encountering these dolphins. By working together, we can help protect and conserve Hector’s and Māui dolphins, ensuring the long-term survival of these incredible species. If you are lucky enough to spot a Hector’s or Māui dolphin, please report the sighting to the Department of Conservation (0800 DOC HOT – 0800 362 468) and remember to keep a safe distance and respect their habitat.
