Bill Rowling

When the Labour Party won power under Norman Kirk in the 1972 election, Rowling was appointed Minister of Finance. This could be seen as a considerable promotion for someone without prior ministerial experience. Rowling's term as Minister of Finance was somewhat turbulent; from late in 1973, a series of externally generated crises, of which the 'oil shocks' were the most serious, destabilised the New Zealand economy. These added to other problems, such as growing overseas debt and falling export prices. A major financial policy during Rowling's tenure was a comprehensive superannuation scheme.[3]

When Norman Kirk died unexpectedly in 1974, Hugh Watt, his deputy, served as acting prime minister for several days while the Labour Party chose a new leader. Rowling was the front-runner to replace Kirk. However, the party's National Executive and the Federation of Labour preferred Watt.[4]

Rowling was officially confirmed as party leader and 30th Prime Minister on 6 September 1974.[5] In the cabinet reshuffle following Kirk's death, Rowling took the foreign affairs portfolio.[6] He was appointed to the Privy Council.[7] Rowling had the option of replacing Kirk in the safe Labour seat of Sydenham but chose to remain in his (more marginal) home electorate of Tasman.[8]

Unlike the pro-life Kirk and Muldoon, Rowling was pro-choice.

Although Rowling served as Minister of Foreign Affairs, the Labour Government concentrated primarily on domestic affairs. Although Rowling's deputy Bob Tizard had replaced him as Minister of Finance, the seriousness of the economic downturn required the Prime Minister's attention. The Government defended heavy overseas borrowing as necessary to protect jobs. In August 1975, the New Zealand dollar was devalued by 15%.[9]

During the 1975 election campaign, Rowling was attacked by the Opposition led by Robert Muldoon, and was generally characterised as being weak and ineffective. Rowling supporters responded with a "Citizens for Rowling" campaign which enlisted high-profile New Zealanders such as Sir Edmund Hillary to praise Rowling's low-key consultative approach. The campaign was labelled as being elitist, and was generally regarded as having backfired on Rowling.[10] The November election was a major defeat for the Labour Party, and Rowling was unable to retain the premiership.

During the late 1970s, Rowling alienated Māori by removing Matiu Rata, the party's effective and well-regarded Māori Affairs spokesman, from the Opposition front bench. Earlier, Rowling had replaced Rata with himself as convenor of Labour's Māori Affairs Committee. Rata complained about the insensitivity of Labour's Māori policy[10] and went on to form his own party, Mana Motuhake, a precursor to the Māori Party.

His approach to the Moyle and O'Brien 'affairs' was regarded as heavy-handed and unnecessary in many circles. In regards to the 'Moyle affair', in which Labour MP Colin Moyle was accused of having a homosexual affair, "it was Rowling who insisted that his close friend, Colin Moyle, must resign".[10] Large numbers protested at the 1977 Labour Party Conference; many in the LGBT community never forgave him.[11]

Rowling, however, managed to retain the party leadership, and gradually managed to improve public perceptions of him. In the 1978 and 1981 elections, Labour actually secured more votes than the National Party but failed to gain a majority of seats.[12]

While Rowling had largely managed to undo his negative image, many people in the Labour Party nevertheless believed that it was time for a change. In 1983 Rowling was replaced as leader by the charismatic David Lange, who went on to defeat Muldoon in the 1984 election. Rowling retired from parliament at the same election.
