Rare Hector’s Dolphins Found in Marlborough Sounds Wildlife Sanctuary
New Zealand is home to some of the rarest dolphins in the world, and the Marlborough Sounds is a sanctuary where these extraordinary creatures thrive. Among them, the Hector’s dolphin stands out for its small size, unique markings, and endangered status. For eco-conscious travellers, spotting a Hector’s dolphin in the wild is a truly special experience that combines adventure with a deep connection to New Zealand’s marine conservation efforts.

As the only company in Marlborough permitted to actively search for and interact with dolphins, E-Ko Tours combines expert knowledge, marine biologist guides, and a commitment to responsible tourism to make every trip both memorable and educational.
Discovering the Hector’s Dolphin
Hector’s dolphins are among the smallest dolphins globally, growing to just 1.5 metres in length. They are endemic to New Zealand, meaning they are found nowhere else on Earth. Their playful and curious nature, coupled with their distinctive rounded dorsal fin—often called the “Mickey Mouse” fin—makes them instantly recognisable.
Key facts about Hector’s dolphins:
- Endangered species with limited distribution around New Zealand coasts.
- Smallest dolphin species in New Zealand, rarely exceeding 1.5 metres.
- Unique black-and-white markings along the body.
- Highly social, often travelling in small pods.
The sheltered waters of Marlborough Sounds provide a safe environment for these dolphins. Calm bays and abundant marine life make it ideal for feeding, socialising, and raising calves.

Why Marlborough Sounds is a Perfect Habitat
The Marlborough Sounds is a network of sunken river valleys and sheltered bays, creating an environment rich in biodiversity. Hector’s dolphins favour these calm waters for several reasons:
- Protection from large predators.
- Abundant food sources, including small fish and squid.
- Clear waters for social interaction and hunting.
This unique environment not only supports Hector’s dolphins but also offers eco-tourists a chance to witness these animals thriving in their natural habitat. E-Ko Tours ensures that every encounter respects the dolphins’ space and well-being, with DOC and WCA-certified practices that prioritise health and safety.
