Blueskin Bay is an estuary in coastal Otago, about 25 km north of Dunedin, New Zealand.
The name also unofficially describes the rural district which includes the northern slopes of Mount Cargill, the southern slopes of the Kilmog, and the townships of Doctors Point, Waitati, Evansdale, Warrington, and Seacliff.
The tidal lagoon is known in MÃÂori as Waiputai. "Blueskin Bay" historically referred to a wider stretch of coast from Heyward Point to Seacliff, including Pà «rÃÂkaunui. The name Blueskin is after Kahuti, a resident MÃÂori personality of the area, whom PÃÂkehàsettlers nicknamed "Blueskin" for the large amount of Tàmoko (traditional MÃÂori tattooing) on his body. The name had been used as the nickname of a notorious 18th-century London criminal, Joseph "Blueskin" Blake.
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.
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.
