The Environment     
The 1990s represented a decade of immense changes in environmental management in New Zealand. This paper outlines the challenges of implementing the widespread reforms started in the 1980s. In terms of the environment, reforms came in the form of a large volume of new legislation and a new system of decentralised planning and management. This paper discusses these changes in the context of a shift toward a new environmental paradigm. Key issues and initiatives of the 1990s are discussed which address sustainability, integration, environmental leadership, and public involvement. Specific strategies are outlined in reference to biodiversity, which has been identified as New Zealand's most pervasive environmental issue. Ongoing challenges for the future include how to better involve stakeholders to incorporate alternative values in decision making.  相似文献

The Economy     
Dissatisfaction amongst large sections of the electorate with the results of 15 years of economic reform on account of the tardy arrival of the supposed benefits of those reforms, led to the return of a centre‐left, Labour–Alliance–Green coalition in the final months of 1999. The coalition immediately set about revising some of the policies of the previous National Party administration. The privatisation of the Accident Compensation Commission was reversed; further privatisation of the diminished stock of state assets halted. Tax on incomes over $NZ 60,000 was raised, as were pay‐outs to pensioners. Interest repayment on student loans was delayed. Market rents for state houses were abolished, as was bulk funding for schools. Arts funding was increased. Government intervention in regional development was revived. Above all else, the Employment Contracts Act was replaced with legislation that would result in a revival of union power. The Prime Minister herself acknowledged New Zealand now lived in world of global magnitudes.  相似文献
