Orca Dolphins Found in Marlborough Sounds Wildlife Sanctuary

The Marlborough Sounds is one of New Zealand’s most remarkable marine environments. Among its diverse wildlife, Orca dolphins—also known as killer whales—stand out as powerful and intelligent predators. Spotting these majestic creatures in the wild is a very rare and unforgettable experience, combining adventure with education for eco-conscious travellers.

E-Ko Tours, based in Picton, offers an unparalleled way to witness Orca in their natural habitat. Sightings are rare and very seasonal. With marine biologist guides, world-class skippers, and a commitment to responsible tourism, every journey into the Marlborough Sounds provides both excitement and insight into these extraordinary marine mammals.

Meet the Orca Dolphins

Orca are the largest members of the dolphin family. They are instantly recognisable by their striking black-and-white markings and tall, triangular dorsal fins. Despite their size, Orca are graceful swimmers and highly social animals, travelling in tight-knit pods with complex social structures.

Key facts about Orca dolphins:

  • Can reach up to 9 metres in length and weigh over 5,000 kilograms.
  • Highly intelligent and communicative, using distinctive vocalisations.
  • Apex predators, feeding on fish, squid, and occasionally other marine mammals.
  • Travel in pods of 2–40 individuals, often led by a matriarch.

In the Marlborough Sounds, Orca are occasional visitors. When they appear, they offer a rare opportunity to observe their hunting techniques, social behaviours, and playful interactions in calm, protected waters.
