Quarantine Island is the largest island in the Otago Harbour. Also known as Kamau Taurua, and was for many years known as St Martin Island. Its primary name derives from the fact that it was Otago's quarantine station between 1861 and 1924. Since 1958 it has been a public reserve, managed jointly by the government and a registered charity, originally named the St Martin Island Community but renamed in 2015 to "Quarantine Island/Kamau Taurua Community Council".
