geographically convenient ways. By way of contrast, Massachusetts, with far less territory, has massively sized counties in comparison even to Pennsylvania's largest, yet each organizes their judicial and incarceration officials similarly. Most counties have a county seat: a city, town, or other named place where its administrative functions are centered. Some New England states use the term shire town to mean "county seat". A handful of counties like Harrison County, Mississippi have two or more county seats, usually located on opposite sides of the county, dating back from the days when travel was difficult. Oceania Australia In the eastern states of Australia, counties are used in the administration of land titles. They do not generally correspond to a level of government, but are used in the identification of parcels of land. The local communities in Australia that share the same post code are usually referred to as suburbs or localities. Several neighboring suburbs are often serviced by the same local government known as a council, whose jurisdiction is officially known as the local government area (LGA). An LGA functions basically the same way as a county of other countries, although it is called instead as "city", "municipality", "shire", "borough", "town", "district" or simple "councils" depending on the state/territory and subregion. It performs municipal services and regulates permits for land uses, but lacks any legislative or law enforcement powers. New Zealand After New Zealand abolished its provinces in 1876, a system of counties similar to other countries' systems was instituted, lasting until 1989. They had chairmen, not mayors as boroughs and cities had; many legislative provisions (such as burial and land subdivision control) were different for the counties. During the second half of the 20th century, many counties received overflow population from nearby cities. The result was often a merger of the two into a district (e.g. Rotorua) or a change of name to either district (e.g. Waimairi) or city (e.g. Manukau City). The Local Government Act 1974 began the process of bringing urban, mixed, and rural councils into the same legislative framework. Substantial reorganisations under that Act resulted in the 1989 shake-up, which covered the country in (non-overlapping) cities and districts and abolished all the counties except for the Chatham Islands County, which survived under that name for a further 6 years but then became a "Territory" under the "Chatham Islands Council".
