Korapuki is a boat-access dive in the Mercury Islands off Whitianga. Weed lines and rocky outcrops ring the island, and the site is known for active water and mixed northern New Zealand marine life rather than coral or dramatic depth. Plan for a boat pickup, no landing on the island, and a side of the island that matches wind and tide on the day.

Community notes to help plan your visit.
Scuba Diving
Diving works around the whole island, especially along weed lines and rocky outcrops.
Freediving
Freedivers and spearos can work the weed lines and rocky edges when the sea is calm enough for controlled pickups.
Snorkeling
Shallow edges may suit snorkelling on calm days, but Korapuki is primarily a boat dive.
