About Maui's dolphin

"Protect the NZ coast and Maui's Dolphin from seabed mining" petition at

Maui's dolphins are generally found close to shore in groups or pods of several dolphins.  They are often seen in water less than 20 metres deep but may also range further offshore. Their characteristics include:

  • Distinctive grey, white and black markings and a short snout. Maui’s and Hector's are the only dolphins with a well-rounded black dorsal fin.
  • Females grow to 1.7 metres long and weigh up to 50 kg. Males are slightly smaller and lighter.
  • The dolphins are known to live up to 20 years.
  • Females are not sexually mature until seven to nine years of age. They produce just one calf every two to four years, making population increase a very slow process.
  • Like other dolphins, Maui’s use echolocation to find their food. They send out high frequency ‘clicks’ that bounce off surrounding objects and fish, giving the dolphins a detailed picture of their surroundings. This sonar is not used all the time, which may be why the dolphins get caught in nets.
