Motutapu Island
Motutapu Island (otherwise known as ''Motutapu'') is a island in the Hauraki Gulf to the northeast of the city of Auckland, New Zealand. The island is part of the Hauraki Gulf Maritime Park. Its full name, rarely used, is ''Te Motutapu a Taikehu'', "The sacred island of Taikehu", Taikehu having been a tohunga (tribal priest) of the Tainui iwi. 'Motutapu', meaning "sacred" or "sanctuary" island, is a term used for various islands in a number of Polynesian cultures. The island can be accessed via regular ferry services departing from Auckland City. Geography Approximately 18,000 years ago during the Last Glacial Maximum when sea levels were over 100 metres lower than present day levels, Motutapu Island was landlocked to the North Island, surrounded by a vast coastal plain where the Hauraki Gulf / Tīkapa Moana exists today. Sea levels began to rise 7,000 years ago, after which Motutapu became an island separated from the rest of New Zealand. The island is now linked by an artif ...

Auckland Volcanic Field
The Auckland volcanic field is an area of monogenetic volcanoes covered by much of the metropolitan area of Auckland, New Zealand's largest city, located in the North Island. The approximately 53 volcanoes in the field have produced a diverse array of maars (explosion craters), tuff rings, scoria cones, and lava flows. With the exception of Rangitoto, no volcano has erupted more than once, but the other eruptions lasted for various periods ranging from a few weeks to several years. Rangitoto erupted several times and recently twice; in an eruption that occurred about 600 years ago, followed by a second eruption approximately 50 years later. The field is fuelled entirely by basaltic magma, unlike the explosive subduction-driven volcanism in the central North Island, such as at Mount Ruapehu and Lake Taupō.Ian E.M. Smith and Sharon R.

Rangitoto Channel
The Rangitoto Channel is one of several passes between the islands of the inner Hauraki Gulf, close to the mouth of the Waitematā Harbour to the east of Auckland in New Zealand. The channel is an important stretch of water as it is the only deep water approach to Auckland Port for large ships such as container cargo ships and passenger cruise liners.Land Information New Zealand Marine chart NZ532 The channel separates the volcanic cone of Rangitoto Island from the East Coast Bays East Coast Bays is a string of small suburbs that form the northernmost part of the North Shore, part of the contiguous Auckland metropolitan area in New Zealand. The suburbs line the north-east coast of the city along the shore of the Haurak ... of the North Shore, to the north of the Waitemata's entrance. The channel was last dredged from a depth of 11.2m to 12.5m in a two-stage process in 2004. The first stage involved the mechanical excavation of hard rock. Blasting was not required. This w ...

Metrosideros Robusta
''Metrosideros robusta'', the northern rātā, is a forest tree endemic to New Zealand. It grows up to or taller, and usually begins its life as a hemiepiphyte high in the branches of a mature forest tree; over centuries the young tree sends descending and girdling roots down and around the trunk of its host, eventually forming a massive, frequently hollow pseudotrunk composed of fused roots. In disturbed ground, or where there are gaps in the forest cover, northern rātā will grow on the ground with a normal but short trunk. Distribution Northern rātā is found in the North Island from Te Paki in the north to Wellington in the south. Formerly widespread, it is now uncommon over large parts of its former range, and is apparently absent from all but the south-east of Hawkes Bay. In the South Island, northern rātā is common from Nelson to Greymouth and Hokitika. It reaches its southern limit near Lake Mahinapua at 42°4′ South latitude. The natural habitat is forest along ...

Pohutukawa
''Metrosideros excelsa'', commonly known as pōhutukawa ( mi, pōhutukawa), New Zealand Christmas tree, New Zealand Christmas bush, and iron tree, is a coastal evergreen tree in the myrtle family, Myrtaceae, that produces a brilliant display of red (or occasionally orange, yellow or white) flowers, each consisting of a mass of stamens. The pōhutukawa is one of twelve ''Metrosideros'' species endemic to New Zealand. Renowned for its vibrant colour and its ability to survive even perched on rocky, precarious cliffs, it has found an important place in New Zealand culture for its strength and beauty, and is regarded as a chiefly tree (') by Māori. Etymology The generic name ''Metrosideros'' derives from the Ancient Greek ' or "heartwood" and ' or "iron". The species name ''excelsa'' is from Latin ', "highest, sublime". ' is a Māori word. Its closest equivalent in other Polynesian languages is the Cook Island Māori word ', referring to a coastal shrub with white berries, ''Soph ...

Scoria Cone
Scoria is a pyroclastic, highly vesicular, dark-colored volcanic rock that was ejected from a volcano as a molten blob and cooled in the air to form discrete grains or clasts.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. It is typically dark in color (generally dark brown, black or purplish-red), and basaltic or andesitic in composition. Scoria is relatively low in density as a result of its numerous macroscopic ellipsoidal vesicles, but in contrast to pumice, all scoria has a specific gravity greater than 1, and sinks in water. The holes or vesicles form when gases that were dissolved in the magma come out of solution as it erupts, creating bubbles in the molten rock, some of which are frozen in place as the rock cools and solidifies. Scoria may form as part of a lava flow, typically near its surface, or as fragmental ejecta ( lapilli, blocks and bombs), for ins ...
