::summary Term for party switching in New Zealand ::

::figure[src="https://upload.wikimedia.org/wikipedia/commons/c/ce/EarleWarSpeech.jpg" caption="jump ship}}'"] ::

Waka jumping is when a New Zealand member of Parliament (MP) either switches political party between elections (taking their parliamentary seat with them and potentially upsetting electoral proportionality in the New Zealand Parliament) or when a list MP's party membership ceases. The action is also called party hopping.

"Waka jumping" is a colloquial term that comes from traditional Māori waka (canoes). Hence, "waka jumping" is analogous to the seafaring term "jump ship", i.e., to leave a ship's crew abruptly and against the terms of a contract (or naval enlistment).

In 2001, legislation was enacted that required MPs to leave Parliament if they left their party; this law expired after the 2005 election. In 2018 a similar law was passed, which requires a defecting MP to give up their seat at the request of the leader of their former party. Electorate MPs may re-contest their seat in a by-election, whereas list MPs are replaced by the next available person on the party list.

A 2013 Fairfax-Ipsos poll found that 76% of those surveyed oppose MPs staying in Parliament if they leave their party.

Legislation

Main article: Electoral (Integrity) Amendment Acts

The implementation of the mixed-member proportional (MMP) electoral system after a referendum in 1993 led to a series of defections and re-alignments as the former two-party system adjusted to the change. This led to the rise and fall of a number of political parties in New Zealand, including the creation of New Zealand First and ACT. The new political climate tended to favour the establishment of new political parties, since in former times dissidents had often simply become independent MPs. In the two parliaments before the 2001 act was passed, 22 MPs defected.

Electoral (Integrity) Amendment Act 2001

The frequency of waka jumping led to the passing of the Electoral (Integrity) Amendment Act 2001, which had been introduced by Labour Party associate justice minister Margaret Wilson in 1999, but had been promoted by Labour's coalition partner Alliance ahead of that year's general election. The act expired at the 2005 election, when a sunset clause came into effect. It required MPs who had entered Parliament via a party list to resign from Parliament if they left that party's parliamentary caucus.

However, parties were able to find ways around this law. When the Alliance party split in 2002 over how to respond to the invasion of Afghanistan, Jim Anderton nominally remained the leader of the Alliance inside Parliament while he campaigned outside Parliament as leader of the newly founded Progressive Party. The resulting uncertainty around the Alliance’s position contributed to Prime Minister Helen Clark's decision to call an early general election in 2002. While the law was in force, it was used once to expel a list MP from Parliament (an electorate MP who changed parties could still fight a by-election, as Tariana Turia did).

In December 2003, the ACT Party caucus voted to expel Donna Awatere Huata, an ACT list MP who became an independent after she had been charged with fraud. The expulsion became the subject of litigation, and Awatere Huata was not expelled from Parliament until a Supreme Court decision handed down in November 2004. A proposed bill to replace the act in 2005 failed.

Electoral (Integrity) Amendment Act 2018 and repeal attempt

The Electoral (Integrity) Amendment Act 2018 received royal assent on 3 October 2018 and entered into force the next day. The provisions on waka jumping now appear as section 55A of the Electoral Act 1993. Under those provisions, members of Parliament who choose to leave their party or are expelled from their party are also expelled from Parliament if the leader of the party under which they were elected issues appropriate notice to the Speaker that the MP should be expelled, with the seat becoming vacant. Unlike the 2001 act, the 2018 act does not have a sunset clause and so remains in force until it is repealed. The act was passed as part of the coalition agreement between New Zealand First and the Labour Party and supported through Parliament "begrudgingly" by the Green Party under the terms of its own confidence-and-supply agreement with Labour.

A member's bill in the name of National Party MP David Carter with the intent of repealing the Electoral (Integrity) Amendment Act 2018 was introduced into Parliament in July 2020. The Green Party defied other government parties to support the repeal bill, with the first reading in Parliament passing by 64 to 55 votes. Carter's Electoral (Integrity Repeal) Amendment Bill was then referred to the justice select committee. After the 2020 New Zealand general election, the bill's second reading was held on 12 May and 14 June 2021, and the Labour Party used its majority of 65 seats to block its passage.

List of MPs who left their party

Below is a list of members who left their party while in parliament. With the introduction of MMP came list MPs, and the potential for a member to be brought into parliament without being voted upon directly.
