New Zealand’s economic reforms beginning in 1984 have been one of the most radical and comprehensive programme of structural adjustment among OECD countries. This paper provides an empirical assessment of how New Zealand’s production structure has changed since the early 1970s. The methodology used is input output analysis. The study is undertaken at the 25-industry level using inter industry transactions for 1971-72, 1976-77, 1981-82, 1986-87, 1990-91 and 1994-95. The results show that some industries have been subject to large structural change and that shifts in New Zealand’s pattern of industrial activity have occurred.
