The Bay of Plenty is a large bight along the northern coast of New Zealand's North Island. It stretches 260 kilometres (160 mi) from the Coromandel Peninsula in the west to Cape Runaway in the east. Called Te Moana-a-Toi in the Māori language after Toi, an early ancestor, the name 'Bay of Plenty' was bestowed by James Cook in 1769 when he noticed the abundant food supplies at several Māori villages there, in stark contrast to observations he had made earlier in Poverty Bay.

Whakaari / White Island, also known as White Island or Whakaari, is an active andesite stratovolcano situated 48 km (30 mi) from the east coast of the North Island of New Zealand, in the Bay of Plenty. The island covers an area of approximately 325 ha, which is just the peak of a much larger submarine volcano.
