Diving in Coromandel Peninsula

The Coromandel Peninsula lies in a north-south direction along the east coast of New Zealand’s North Island. With 85 kilometers of coastline surrounded by the Bay of Plenty, the Hauraki Gulf, and the Firth of Thames, there is no shortage of diving in the Coromandel Peninsula. Particularly, the peninsula’s east coast is a diving and boating mecca with dozens of islands boasting pristine beaches and crystal-clear water.
Islands like Mercury and Alderman sustain an impressive amount of marine life while remaining relatively accessible. The Hauraki Gulf surrounds the peninsula, and relaxed townships scatter the coastline, offering remarkable views both above and under the water.

The dive conditions here are similar to the Poor Knights Marine Reserve, with 15C degree water in the winter (Aug) and 23C in the summer (Feb). You can find many of New Zealand’s dive centers in this area, with charters leaving from Tairua and Whitianga. Whitianga is easily accessible from Auckland via a 2.5-hour drive.

Some of the best diving in New Zealand sits right offshore near Aldermen and Mercury Islands. The underwater topography and marine life diversity will thrill even the most seasoned diver. Day trips out to these islands are very popular, so book in advance!
