Whārangi 5. Constitutional referendums

Ngā whakaahua

Instead of having a single written constitution, a variety of laws and long-standing conventions have created New Zealand’s constitutional structures. Until 1993 the Electoral Act 1956 provided the legislation for the voting system. Entrenched clauses in the act could only be changed by either a vote by at least 75% of all the members of Parliament or by a majority vote in a referendum. One of these clauses entrenched the three-year parliamentary term. New Zealand has twice held referendums on whether the maximum term of Parliament should be three years or four.

Referendums on parliamentary terms

The first referendum on the term of Parliament was held on 23 September 1967, at the same time as the referendum on hotel opening hours. Of those who voted (69% of registered electors), 68% favoured retaining a three-year parliamentary term. In the second referendum on this matter, in 1990, 69% of those who voted supported the three-year term. This referendum was held in conjunction with the general election, with 85% of registered electors voting.

Neither referendum was conducted directly under the provisions of the Electoral Act 1956. As a result, had a majority in either referendum favoured a four-year term, the will of the public could only have been formally implemented by a vote of at least 75% of the members of Parliament. The results of both referendums, rejecting the extension of the parliamentary term, made this issue irrelevant.

The Campaign for Better Government

The 1993 constitutional referendum campaign saw a new anti-MMP lobby group emerge, the Campaign for Better Government (CBG), led by Telecom chairman Peter Shirtcliffe. The CBG reportedly spent over $1.5 million on their campaign, compared to the pro-MMP Electoral Reform Coalition’s spending of $181,000. The CBG’s campaign may have increased support for first-past-the-post (FPP), which received 46% of the vote in 1993. On the other hand it has been argued that the CBG was seen by many as simply a lobby group for business interests opposed to proportional representation.

The referendum on voting systems 1993

New Zealand’s only constitutional referendum held directly as a result of the provisions in the Electoral Act 1956 – which made it binding – was held in November 1993. It asked voters whether or not they wanted to replace the first-past-the-post voting system with the mixed-member proportional (MMP) voting system. A small but clear majority of electors (54%) said they did. The referendum was held in conjunction with the general election, and 85% of registered voters participated.

The result had important constitutional consequences. The Electoral Act 1993 replaced the Electoral Act 1956 as the legislative basis of New Zealand’s voting system. Parliament became significantly larger (increasing from 99 MPs to 120). The voting system became proportional (parties’ shares of seats in Parliament reflected their share of the nation-wide vote) and, until 2014, every administration since the mid-1990s was a coalition government.
