New Zealand is no different in this regard. Perhaps what does distinguish the situation in New Zealand is the rate and extent of change. There is reasonable agreement that the “New Zealand experiment” has resulted in one of the most successful but most dramatically changed modern market economies, transforming New Zealand from one of the most regulated of the developed economies to one of the least regulated (McMillan 1998). In particular, the liberalisation of employment laws has allowed employers much greater flexibility in employment contracts reflected in significant adjustments to many conditions of work, all of which can be expected to have an impact on the health of workers and their families (see Feyer & Broom 2001 for a review).
