Voting in New Zealand was introduced after colonisation by British settlers. The first New Zealand Constitution Act was passed in 1852, and the first parliamentary elections were held the following year.

Between 1853 and 1876, elections were held five years apart. In the mid-19th century, provincial council elections attracted more press attention, more candidates and more voters than general elections; the provincial councils were abolished in 1876. Since 1879, elections have typically been held every three years. In times of crisis such as wars or earthquakes, elections have been delayed, and governments have occasionally called early ('snap') elections. Because the New Zealand system of government is relatively centralised, today most electoral and political attention is focused on general elections rather than local elections (which are also held at three-year intervals).

Voting in New Zealand

Until 1879 only male property owners could vote in general electorates, which meant that a disproportionate number of electors lived in the countryside. However, Māori electorates were created in 1867, in which all Māori men could vote. Women were enfranchised in 1893, establishing universal suffrage. The introduction of the mixed-member proportional (MMP) system in 1996 provides that all votes contribute to the election result, not just a plurality.

While voter turnout is relatively high by international democratic standards, trends in New Zealand show a general decline since the 1960s, although turnout increased over the last four general elections (, , and ).

Early local body elections

The first notable election held in the new colony was the election of the first Wellington Town council pursuant to the Municipal Corporations Act in October 1842. It was open to all "Burgessers". These were undoubtedly male only, though it is not clear whether it was only Europeans who were permitted to vote and what age restrictions applied. There was a one-pound poll tax, rather than a property requirement. This led to accusations of vote buying by those wealthy enough to pay for the registration of indigent electors, however the practice was so prevalent all those candidates who were ultimately successful used the tactic. In contrast to later national elections this local election also saw the emergence of a nascent working class party under the auspices of the Working Men's Association and the Mechanic's Institute.

Voting following the New Zealand Constitution Act 1852

The first national elections in New Zealand took place in 1853, the year after the British government passed the New Zealand Constitution Act 1852. This measure granted limited self-rule to the settlers in New Zealand, who had grown increasingly frustrated with the colonial authorities (and particularly with the nearly unlimited power of the Governor). The Constitution Act established a bicameral parliament, with the lower house (the House of Representatives) to be elected every five years. The upper House (the appointed Legislative Council) was later abolished in 1950.

Initially, the standards for suffrage were relatively high. To vote, a person needed to be:

male, a British subject, aged at least 21 years old, an owner of land worth at least £50, or payer of a certain amount in yearly rental (£10 for farmland or a city house, or £5 for a rural house); and, not be serving a criminal sentence for treason, for a felony, or for another serious offence.

In theory, this would have allowed Māori men to vote, but electoral regulations excluded communally-held land from counting towards the property qualification (quite a common restriction in electoral systems of the time). In these circumstances, many Māori (most of whom lived in accordance with traditional customs of land-ownership) could not vote. Historians debate whether or not the system deliberately excluded Māori in this way. There was concern amongst many settlers that the "uncivilized" Māori would be, if enfranchised, a voting bloc with the numerical strength to outvote Europeans. However, most Māori had little interest in a "settler parliament" that they saw as having little relevance to them.

Despite the exclusion of Māori and of women, New Zealand's voting franchise appeared highly liberal when compared to that of many other countries at the time. At the time of the passing of the Constitution Act, an estimated three-quarters of the adult male European population in New Zealand had the right to vote. This contrasts with the situation in Britain, where the equivalent figure approximated to a fifth of the adult male population.
