Sir Robert David "Rob" Muldoon, GCMG, CH (25 September 1921 – 5 August 1992) served as the 31st Prime Minister of New Zealand from 1975 to 1984, as leader of the governing National party.

Muldoon remains one of the most complex, fascinating, and polarising figures in New Zealand history. He divided people into camps of those who loved him and those who hated him; very few people, except those born after his fall, remained neutral. To his enemies, "Piggy" Muldoon was a dictatorial Prime Minister who nearly destroyed both New Zealand's economy and New Zealand society through his arrogance.
