High Quality Content by WIKIPEDIA articles! Pitt Island or Rangiauria is the second largest island in the Chatham Islands, originally known as Rekohu. There is a School, a wharf, a church and a landing strip for light planes on Pitt Island. Air Chathams provide the light plane service between the islands. As there is no shop on the island, a supply ship visits Pitt Island about every three months. Fuel, stores and other goods are unloaded. Live sheep and cattle are taken back to mainland New Zealand.
