Coastal Gems logo.

Visitors to the marine reserve will see sandy flats, reefs, boulder and cobble fields, and all the sea creatures and plants which thrive in these habitats. The area is also popular with walkers as it encompasses the beautiful coast around Hahei and Cathedral Cove.

The area was named after Hei, a tohunga of the Te Arawa waka who claimed the area for his people.

The reserve covers the marine area north-east of Hahei and Cooks Bluff between Mahurangi and Motukorure Islands on the Coromandel Peninsula.
