White Island (Whakaari) sits in the Bay of Plenty and is New Zealand's only active marine volcano, and that geology defines every dive here. Underwater fumaroles and geothermal vents release gas bubbles across the volcanic topography, creating an environment found nowhere else in the country. The eight sites in the database range from sheltered bays with hot springs to offshore pinnacles and the Seafire wreck, covering reef, drop-off, pinnacle, and wreck terrain. Water temperatures peak in late summer and cool through winter, when a wetsuit with adequate thermal protection is essential. Permits are required due to the island's active volcanic status, and all sites are reached by boat from Whakatane.
