stays in the hauraki gulf year round

Size
Length: 12–15 m, Weight: 12,000–20,000 kg
Lifespan
50–70 years
Diet
Carnivorous. Feeds on krill, small fish (especially anchovy and pilchard) and squid. A filter feeder that uses baleen plates. Often feeds near the surface in coastal waters.
Habitat
Coastal and offshore waters, especially near upwelling zones. In New Zealand, commonly seen in the Hauraki Gulf year-round. Prefers warmer waters than other rorquals.
Range
Worldwide in tropical and subtropical waters. In New Zealand, resident in the Hauraki Gulf and off the North Island east coast. Most common in northern waters year-round.
Endemism
Native
Main Threats
Ship strikes are the primary threat in the Hauraki Gulf. Underwater noise from seismic surveys and shipping. Entanglement in fishing gear. Climate change affecting prey distribution.
Population
A resident population of approximately 200–250 whales lives in the Hauraki Gulf year-round. This is one of the few resident Bryde's whale populations in the world. Ship strikes are a significant local threat.
Conservation Status
Not Threatened
Human Risk

Te Ao Māori
Bryde's whales have no specific Māori name, as early Māori did not distinguish them from other rorquals. Their resident population in the Hauraki Gulf is a modern discovery, made through systematic survey work in the late 20th century. To the iwi of the gulf, they are part of the wider whaling tradition. They do not hold the same ancestral significance as the tohorā (southern right whale) or the paikea (humpback). They are the quiet residents of the gulf, seen but not celebrated.
Named after Johan Bryde, a Norwegian whaler, this whale holds a unique position in New Zealand waters. A resident population lives in the Hauraki Gulf year-round. It is one of the few places globally where these whales are seen close to a major city. Unlike other rorquals, Bryde's whales do not undertake long migrations. They remain in the same waters throughout the year, feeding consistently. The Bryde's whale belongs to the rorqual family, which includes blue whales and humpbacks. It possesses characteristic throat grooves that allow it to expand its mouth to engulf vast quantities of water and prey. Smaller than its famous cousins, it reaches only about fifteen metres in length. Its body is dark grey on top and lighter below, with a subtle, mottled pattern unique to each individual. Three prominent ridges on the top of its head distinguish it from other rorquals. In the Hauraki Gulf, these whales often feed near the surface. They lunge through schools of anchovy and pilchard, mouths open wide, throat grooves stretched to capacity. Gulls and terns gather above, hoping to snatch scraps. This spectacle occurs almost daily. Most Aucklanders have no idea it is happening. The whales live their lives just beyond the shipping lanes while the city bustles nearby. Ship strikes pose the biggest threat to Bryde's whales in New Zealand. The Hauraki Gulf is one of the busiest shipping corridors in the country. The whales feed in the same waters that ships traverse. A collision with a large vessel is almost always fatal. Shipping lanes have been adjusted in response. Speed restrictions have been implemented in parts of the gulf. The whales are slowly learning to share their home with the ships. It is a dangerous coexistence.
