Deputy Prime Minister of New Zealand

The Deputy Prime Minister of New Zealand is the second most senior minister in the Government of New Zealand, although this seniority does not necessarily translate into power.

Generally, the position is held by the deputy leader of the ruling party, but now that the MMP electoral system makes coalitions more likely, the role may instead go to the leader of a junior party. This occurred with Winston Peters, leader of New Zealand First, and Jim Anderton, leader of the Alliance.

The post of Deputy Prime Minister was formally established in 1949, although it informally existed prior to then. Since 1949, seventeen people have held the position (one of them doing so twice). Of those people, only Holyoake, Marshall, Watt, Muldoon, Palmer, Clark and English have eventually served as Prime Minister.

Little scholarly attention has focused on deputy prime ministers in New Zealand or elsewhere. In 2009, an article by Steven Barnes appeared in Political Science where nine 'qualities' of deputy prime ministership were identified: temperament; relationships with their Cabinet and caucus; relationships with their party; popularity with the public; media skills; achievements as Deputy Prime Minister; relationship with the Prime Minister; leadership ambition; and method of succession. Barnes conducted a survey of journalists, academics, and former Members of Parliament to rank New Zealand's Deputy Prime Ministers since 1960. Across the nine deputy prime minister 'qualities', Don McKinnon achieved the number one ranking, followed by Brian Talboys, Michael Cullen, and John Marshall. In a second 'overall' ranking, Cullen was ranked number one, followed by Talboys, McKinnon, and Marshall. Jim Anderton, Winston Peters, and Bob Tizard were ranked lowest in both sections of the survey.
