A number of factors resulted in a sharp drop in support for the Social Credit Party in the general election of 1984. One of these factors was Beetham's ill health. A major heart attack in 1983 curtailed his activities for much of that year and early 1984, and his disappearance from the public view made it possible for a new political party, the New Zealand Party (founded by millionaire businessman Bob Jones) to fill the vacuum. This party succeeded in attracting much of the protest vote that Social Credit had previously enjoyed. Another major factor was Beetham's earlier support for the construction of the Clyde Dam, which was strongly opposed by Social Credit's rank and file with many supporters accusing him of betrayal.
