Although it won only one seat in the 52-member House of Representatives, most of its votes came at the expense of the Alliance, allowing the Indo-Fijian-dominated National Federation Party to become the largest party in the House and precipitating a constitutional crisis.
Early elections were held in September 1977, in which the party lost its only seat and saw its vote share halved.
In the late 1990s, the FNUFP merged with the Vanua Tako Lavo Party, which shared its strong opposition to the 1997 constitution.
The merged party, known as the Nationalist Vanua Tako Lavo Party, was implicated by Maciu Navakasuasua, who was convicted of offences related to the Fiji coup of 2000, in the planning of the coup which deposed the elected government of Prime Minister Mahendra Chaudhry.
