Urban areas based on 2018 standard

Statistics New Zealand creates standards for statistical geographic areas that are the basis for determining population figures. Statistics New Zealand announced in 2017 that the Statistical Standard for Geographic Areas 2018 (SSGA18) would replace the New Zealand Standard Areas Classification 1992 (NZSAC92). The change impacted Wellington most, by splitting it into four urban areas, being the Wellington city and Lower Hutt city "major urban areas" and Porirua and Upper Hutt "large urban areas". Wellington as defined by Statistics New Zealand approximately halved in size, and Lower Hutt entered the city rankings in sixth place between Tauranga and Dunedin.^[3]

The table below contains all "major urban areas" (100,000 or more residents) and all "large urban areas" (30,000 to 99,999 residents).^[4] The urban area that will next move from the "medium urban area" category to the "large urban area" category is Paraparaumu (30,800).

Functional urban areas (metropolitan areas)

Functional urban areas (FUAs) are geographic areas which represent the functional extent of major, large and medium urban areas, based on commuting patterns. Functional urban areas correspond to New Zealand's metropolitan areas.^[6]

FUA populations are as at the 2018 Census.^[6]

Populations of present-day city (and Auckland) councils

The populations given are the latest (June 2018)^[7] Statistics New Zealand estimated resident populations.

Many cities were reorganised into districts by the Local Government Commission in 1989 under the Local Government Act 1974, for example Timaru. Other urban areas that are no longer cities, such as Rotorua and Whangārei, have higher populations than some present cities. The most recently proclaimed city is Tauranga, which became a city, for the second time, from 1 March 2004. Christchurch (1862 and 1868) and Invercargill (1930 and 1991) have also been declared cities more than once.

Under Section 27 of the Local Government Act 2002, a district may become a city by either a "reorganisation scheme" with the Local Government Commission, or under Section 27(1) it may apply for a change in status under Schedule 3, Clause 7. The new city must have "a population of not less than 50,000 persons", be "predominantly urban" and "a distinct entity and a major centre of activity within the region" (or regions) that it is encompassed by. Existing cities are grandfathered under Schedule 2, Part 2 of the Act. The only new city council so far under this section is the Tauranga City Council, from 1 March 2004.

Previously, under Section 37L of the Local Government Act 1974, new cities could only be formed from a "reorganisation scheme". The same criteria were used. The last city to be constituted under this section was Invercargill, which was re-reorganised into a city in 1991.

In 1991, the Lower Hutt City Council became the Hutt City Council by a special Act of Parliament which did not change the name of the city of Lower Hutt; the city's coat of arms still refers to the "City of Lower Hutt".

Letters patent

In the United Kingdom city status is a special status granted by the monarch, usually by the issuing of letters patent. Between the 16th Century and 1888, city status was associated with the presence of a diocesan cathedral. In 1841 the Diocese of New Zealand was established, based in Auckland however no letters patent were ever issued. The Diocese of New Zealand however was split in 1856 with the southern part became the Diocese of Christchurch. Christchurch was subsequently issued letters patent by Queen Victoria and became the "City of Christchurch".^[9] Despite the formation of other dioceses in New Zealand, the only other city to be subsequently issued letters patent was Nelson in 1858.^[8][10]

Electorates

Under the Provincial Councils Act 1851, the Governor had the right to establish electorates for provincial legislative councils.^[11] On 21 May 1852, Governor George Grey proclaimed electorates for New Ulster. Although the proclamation explicitly defined Auckland as a "town" for the purpose of property franchise, it later defined the electorate "City of Auckland". This ambiguous proclamation was the first official use of the term "city" in New Zealand legislation. The electorates of New Munster were also declared a short time later on 1 June. Likewise, Wellington was described as a town for property franchise, but more ambiguously established an electorate referred in different parts of the proclamation as either "City of Wellington" or "Town of Wellington". The provinces of New Ulster and New Munster were disestablished only a month later by the New Zealand Constitution Act 1852, however, the electorates of both "City of Auckland" and "City of Wellington" were carried forward to the first nationwide election of 1853.^[8]

City councils

The first municipal council to bear the title of "city council" was the Auckland City Council formed in 1854 by act of the Auckland Provincial Council.^[12] Following the election of an anti-taxation superintendent in March 1855, the Auckland City Council was dissolved and formally disestablished 1856.^[8] A new Auckland City Council would be established in 1871, which was later was merged into Auckland Council in 2010.^[13]

The Christchurch City Council was formed by an act of the Canterbury Provincial Council which received Royal assent on 31 January 1863.^[14] The council has been active since and is therefore the longest continuously operating city council in New Zealand.^[8][9]

A legal oddity also provides Dunedin with a minor claim to being New Zealand's oldest city. Legal disputes over the powers delegated to the newly formed Dunedin City Council in 1865,^[15] resulted in the central government stepping in and confirming its powers.^[16] Consequently, Dunedin City council was the first council recognised in central government law. Furthermore, the central government passed legislation in 1868 to better regulate municipal councils across the country. Dunedin was already under the provisions and was therefore unaffected. The new act brought all other "city councils" in New Zealand under the central government regulations as "borough councils". The name change, however, was only due to an oversight in the language of the act and an amendment was made in November 1868 allowing some councils to revert to using the title of "city council". As the act, and therefore the brief name change, did not apply to Dunedin, Dunedin City Council can claim to have the longest continuous use of the title "city council".^[8][17]

Summary of claims as New Zealand's first city

Cities, 1877 to 1989

The schedule of cities in New Zealand was brought under central government control in 1867,^[17] but continued to be sporadically applied. From 1886 the definition of a city was changed to any borough with a population of 20,000 or more.^[18] This value was increased to 50,000 in 1989.^[8][19]

Up to October 1989, the Local Government Commission undertook reorganisations of local government. As a result, some cities were reorganised into other larger cities or changed to districts, and some of these areas are still considered cities by many New Zealanders. This is a list as at c. 1986.
