Ōpāhekeheke Island is located in the southwestern Kaipara Harbour, near the Kawau Parua Inlet and the mouth of Te Kowhai Creek on Te Korowai-o-Te-Tonga Peninsula.[2] It reaches a height of 18 m (59 ft) above sea level.[2] The island is a depositional sand bank, surrounded by intertidal flats and mangroves.[3]
Biodiversity
The island is forested by semi-mature and regenerating coastal forest.[3] The great white shark has been found in the waters surrounding the island, often attracted by Kaipara Harbour fishermen, who habitually discard unwanted fish such as spotted estuary smooth-hounds into a location known as "The Gutter".[4]
