Cathedral Cove

Te Whanganui-A-Hei Marine Reserve is in the southern part of Mercury Bay on the Coromandel Peninsula in New Zealand covering an area of 840 hectares. On the coast of the mainland, it stretches from Cook Bluff in the north-west to the northern end of Hahei Beach in the south-east. Its offshore extremes run from Motukorure Island through Waikaranga Island to Okorotere Island and the northern end of Mahurangi Island.

Part of the marine reserve lies off the Cathedral Cove Recreation Reserve, which runs from the northern end of Hahei Beach in the south-east to beyond Cathedral Cove in the north-west. With attractions such as a natural rock archway and neighbouring beaches at Cathedral Cove, the area is very popular with tourists, and receives around 150,000 visitors per year.
