 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.
Rangitoto Island is a volcanic island in the Hauraki Gulf near Auckland, New Zealand.
 The 5.5 km wide island is an iconic and widely visible landmark of Auckland with its distinctive symmetrical shield volcano cone rising 260 metres (850 ft) high over the Hauraki Gulf.
 Rangitoto is the most recent and the largest (2311 hectares) of the approximately 50 volcanoes of the Auckland volcanic field.
