Long Island is located in the Marlborough Sounds of New Zealand.  It is just over 1.41 km² in area with a length of 4 km ( the long axis being aligned North-east/South-west)and a maximum width of 1 km - hence the name "Long Island".  The island was reserved for public utility on the 26th of March 1926 and soon after became a farm which ran between 300 and 400 sheep until January 14, 1926 when the island became a scenic reserve.  With the removal of stock in the 1930s the island has been left to regenerate back into native bush.  In April 1993 the Long Island-Kokomohua Marine reserve was created around Long island and the tiny Kokomohua islands off its northern tip - it extends 460 m offshore from the high water mark around the islands and was the first Marine reserve to be created in the South Island.  The island itself is also an important wildlife refuge and a number of species of threatened endemic birds which have been reintroduced to it including little spotted kiwi (late 1980s), yellow crowned kākāriki (2001) and South Island saddleback (2005) - all these reintroductions have been successful with healthy breeding populations of each species now present on the Island.

The Long Island AVA is an American Viticultural Area encompassing Nassau and Suffolk counties of New York, including the smaller offshore islands in those counties.  The AVA was established in 2001, over 15 years after two smaller AVAs were created at the eastern end of Long Island.  The Long Island AVA designation was promoted as a benefit for some wineries located just outside the two smaller AVAs and for wineries that wanted to create wines that use blends from vineyards in different parts of the island.  It was also developed and promoted as a consumer protection of the Long Island name; AVAs require that a minimum of 85% of the fruit used in the designated wine is grown within the borders of the region.  The "Long Island" AVA was authored by veteran Long Island winemaker Richard Olsen-Harbich who also authored the "The Hamptons, Long Island" and "North Fork of Long Island" AVAs in the mid-1980s.
