Ruapuke Island is one of the southernmost islands in New Zealand's main chain of islands. It lies 25 kilometres to the southeast of Bluff and 32 kilometres northeast of Oban on Stewart Island. The island covers an area of about 16 km2.
RUAPUKEISLAND: Low lying island, 13km by 6km, 1600ha in area, in the eastern approaches to Foveaux Strait, 20km south-east from Bluff, 30km north-east from Stewart Island, Southland District.
The Island is privately owned, and most of the area, apart from a few strands of bush, is now either scrub or open land used for sheep grazing.
In the early 1800s RuapukeIsland was a stronghold for the Ngai Tahu paramount chief Tuhawaiki (Bloody Jack), and supported the largest Maori population in southern New Zealand.
