In 1984, the highly interventionist New Zealand economy was struggling. Between 1974 and 1984, inflation was 11-17% (dropping to 7% in 1983 after wage and price freezes), the deficit was 3-9% of GDP, and real GDP growth averaged 1% per year. In 1984, unemployment was at a historic high of 5%, and there was an imminent foreign exchange crisis.
