Leader of the Opposition (New Zealand) in the context of David Shearer

Sir Robert David Muldoon GCMG CH PC (/mʌlˈduːn/; 25 September 1921 – 5 August 1992) was a New Zealand politician who served as the 31st prime minister of New Zealand, from 1975 to 1984, while leader of the National Party. Departing from National Party convention, Muldoon was a right-wing populist and economic nationalist, with a distinctive public persona described as reactionary, aggressive, and abrasive.

After a troubled childhood, Muldoon served as a corporal and sergeant in the army in the Second World War. After a career as a cost accountant, he was elected to the House of Representatives at the 1960 general election as the Member of Parliament (MP) for Tamaki, representing the National Party. Muldoon rose in the Second National Government to serve successively as Minister of Tourism (1967), Minister of Finance (1967–1972), and Deputy Prime Minister (1972). Over this time he built up an informal but solid backing amongst National's mostly rural right faction, which he called "Rob's Mob". After National lost the 1972 general election to the Labour Party, Muldoon used his connections to oust moderate party leader Jack Marshall and take his place, becoming Leader of the Opposition in 1974. Through Muldoon's ideological blend of moderate social liberalism and protectionist right-wing populism ("counterpunching", a term he coined) and the promise of a lucrative superannuation scheme, National enjoyed a resurgence. The early death of prime minister Norman Kirk severely weakened the Labour Party, and Muldoon soon led National to a decisive victory in the 1975 general election.
