Official Opposition (New Zealand)

Her Majesty's Loyal Opposition, or commonly the Official Opposition, in New Zealand is usually the largest political party or coalition which is not a member of the ruling government. This means that the political party, while still involved with the political process in New Zealand, they do not have ministers or their supporters in a position of power. This is usually the second-largest party in a legislative house, although in certain unusual circumstances it may be the largest party (due to a larger Government bloc) or even a third or fourth party.

The Opposition aims to hold the government accountable and to present itself to the electorate as a credible government in waiting. For example, during Question Time, Opposition spokespersons will ask questions of Ministers with the aim of highlighting a weakness or embarrassing the government. Oppositions also engage in Parliamentary gestures such as refusal to grant confidence or voting down the Budget; however, as most governments comfortably retain the Parliamentary majority necessary to preserve confidence and supply, such gestures are largely symbolic.

With the introduction of MMP in 1996 (after referendums in 1992 and 1993), there was consideration to remove the official role of the Opposition; with several parties outside the government, it was no longer clear which party, if any, was 'the' opposition. This is complicated more by parties which occasionally act with the government and at other times vote against it. The unusual positioning that developed after the 2005 election further complicated the idea of 'opposition'. However, the continued dominance of the political scene by the National and Labour Parties means that the official Opposition has been retained, and inevitably the official Opposition is whichever of the National and Labour parties is not leading a Government at the time. Parties and Members of Parliament outside the government which do not work with the official Opposition party are said to "sit on the cross-benches".
