The full name of the island in Māori is: Ngā Rangi-i-totongia-a Tama-te-kapua (“the day the blood of Tamatekapua was shed”).
Rangitoto Island is a graceful, almost symmetrical, volcanic cone which dominates the skyline to the north-east of Auckland City. Formed and last erupted some circa 1400 and 1450 AD.
It is the youngest and by far the largest of the ca. 50 volcanoes in the basaltic Auckland volcanic field. The estimated volume of basalt in the volcano (2 cubic kilometres) is about half the volume of all of the basalt in the field (Lindsay et al.)
