The tidal lagoon is known in Māori as Waiputai.[1] "Blueskin Bay" historically referred to a wider stretch of coast from Heyward Point to Seacliff, including Pūrākaunui.[2] The name Blueskin is after Kahuti, a resident Maori personality of the area, whom Pakeha settlers nicknamed "Blueskin" for the large amount of Tā moko (traditional Maori tattooing) on his body. The name had been used as the nickname of a notorious 18th-century London criminal, Joseph "Blueskin" Blake.[2]
The estuary
The Waitati River and Careys Creek enter Blueskin Bay at its southwest and northwest corners. A long sand spit from the northern headland closes the bay to a small channel to the Pacific Ocean at the southeast corner. Rabbit Island lies just inside this entrance.
Critically endangered, endemic Hector's dolphins live around the bay.
Shellfish
Blueskin Bay is a popular site for gathering clams, locally known as "cockles". Along with families collecting the shellfish for personal consumption, Southern Clams Ltd collects clams commercially for export.[2]
