Title: Whale watching in New Zealand
Passage: Whale watching in New Zealand is predominantly centered around the areas of Kaikoura and the Hauraki Gulf.  Known as the 'whale capital', Kaikoura is a world-famous whale watching site, in particular for sperm whales which is currently the most abundant of large whales in New Zealand waters.  The Hauraki Gulf Marine Park (just outside Auckland city) is also a significant whale watching area with a resident population of Bryde's Whales commonly viewed alongside other cetaceans Common Dolphins, Bottlenose Dolphins and Orca.  Whale watching is also offered in other locations, often as eco-tours and in conjunction with dolphin watching.  Land-based whale watching from New Zealand's last whaling station, which closed in 1964, is undertaken for scientific purposes, mostly by ex-whalers.  Some compilations of sighting footages are available on YouTube.
Title: Killer whale
Passage: The killer whale or orca ("Orcinus orca") is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member.  Killer whales have a diverse diet, although individual populations often specialize in particular types of prey.  Some feed exclusively on fish, while others hunt marine mammals such as seals and dolphins.  They have been known to attack baleen whale calves, and even adult whales.  Killer whales are apex predators, as there is no animal that preys on them.  Killer whales are considered a cosmopolitan species, and can be found in each of the world's oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas.
Title: Coromandel Peninsula
Passage: The Coromandel Peninsula on the North Island of New Zealand extends 85 kilometres north from the western end of the Bay of Plenty, forming a natural barrier to protect the Hauraki Gulf and the Firth of Thames in the west from the Pacific Ocean to the east.  It is 40 kilometres wide at its broadest point.  Almost the entire population lies on the narrow coastal strips fronting the Hauraki Gulf and the Bay of Plenty.  In fine weather the peninsula is clearly visible from Auckland, the country's biggest city, which lies on the far shore of the Hauraki Gulf, 55 kilometres to the west.  The peninsula is part of the local government areas of Thames-Coromandel District and the Waikato Region.
