Tank Farm

Originally a freshwater lake, it later became a tidal lagoon when the sea levels rose after the last ice age.

[1] Tank Farm and neighbouring Onepoto were fresh water lakes when sea levels were lower using the Last Glacial Maximum.

As sea levels rose, the waters of the Waitematā Harbour breached the tuff rings of the craters, becoming tidal lagoons.

Matakamokamo is an ancestral figure in Māori mythology tradition who, during a domestic argument, is said to have inadvertently cursed the goddess of fire, Mahuika.

As punishment, the goddess called on the parent god Mataoho, who had the necessary powers, to send up numerous volcanic eruptions to plague the hot-tempered man and his wife Matakerepo.
