As a
unitary authority, the Nelson City Council has the combined responsibilities and functions of both a
territorial (local) and
regional council. This is different from most other local authorities in New Zealand. More often, a regional council is a separate organisation with several territorial authorities (city or district councils) within its borders. Other unitary authorities are the
Auckland Council,
Gisborne District Council,
Marlborough District Council,
Tasman District Council and the
Chatham Islands Council. The
mayor of Nelson and 12 councillors are elected every three years. The elections are held under the
first-past-the-post electoral system, as part of nationwide
local elections. They are conducted by post over a three-week period to make it as convenient as possible for people to vote. The other option permitted under the Local Electoral Act 2001, but not currently used in Nelson, is the
single transferable vote system. Multiple-member districts are used. Electors vote by ranking candidates in order of preference by placing a number beside candidates' names. The elector can mark a preference for one or up to the total number of candidates on the paper. The number of votes required for a candidate to be elected, the quota, depends on the number of positions to be filled and the number of valid votes. (Election of mayor may be held using the
Instant-runoff vote method.) Under the
Local Electoral Act 2002, the Nelson City Council can resolve to change the electoral system to be used for the next two elections, and it must review this decision every six years. A referendum was held in 2003 to decide which electoral system would be used for the 2004 and 2007 Nelson City Council elections, with the outcome that the first-past-the-post system was retained. The 2008 review retained that system for the 2010 and 2013 elections. == Current councillors ==
