Sei whale

(Balenoptera borealis)

IUCN Status: Endangered

NZ Classification: Data Deficient

Reaching up to approximately 15m in the Southern Hemisphere, they have a similar size and appearance to the Hauraki Gulf’s resident Bryde’s whales. Similarly to Bryde’s whales, they also have a short dive time of approx 5-10 minutes.

Sei whales are one of the fastest species of baleen whale and can swim at speeds of up to 30 knots (55km/hr).

While we see Bryde’s whales year-round in the Hauraki Gulf, sei whales are only occasional visitors.
