Spurred by public disillusionment in the political system, Labour campaigned in 1981 and 1984 on a promise to establish a Royal Commission into the electoral system. Following their election into government in 1984, Labour established the Royal Commission into the Electoral System, and the commission's 1986 report recommended the adoption of mixed-member proportional representation (MMP). After the government sidelining the issue for years, the Bolger National government responded to public pressure by holding an indicative referendum on the electoral system in 1992. After an overwhelming majority for change, a second, binding referendum was held in 1993 asking voters to choose between FPP and MMP.
