Placenames in New Zealand derive largely from British and Māori origins. An overview of naming practices can be found at New Zealand place names.
Many of the locations in the southern South Island of New Zealand, especially those in Central Otago and the Maniototo, were named by John Turnbull Thomson, who had surveyed the area in the late 1850s. Many of these placenames are of Northumbrian origin, as was Thomson himself.[citation needed]
There is a widespread, probably apocryphal, belief that the naming of many places was through a disagreement with the New Zealand surveying authorities. It has long been suggested that Thomson originally intended to give either classical or traditional Māori names to many places, but these names were refused. In response, Thomson gave prosaic Northumbrian names to them, often simply in the form of a Northumbrian dialectic name for an animal.[page needed] The Maniototo region around the town of Ranfurly is rife with such names as Kyeburn, Gimmerburn, Hoggetburn, and Wedderburn as a result. Ranfurly itself was originally called "Eweburn". The area is still occasionally referred to as "Thomson's Barnyard" or the "Farmyard Patch".[citation needed]

He claimed possession for Great Britain and named the islands after the First Lord of the Admiralty, John Pitt, 2nd Earl of Chatham.
