2003 New Zealand National Integrity System Study

The 2003 New Zealand NIS study goes beyond a focus on corruption and the features of the governance framework. The narrative sections and recommendations also assess governance in NZ against standards that reflect citizen expectations, legal requirements and international best practises. The NIS study identifies areas where action is required to strengthen transparency and accountability in NZ and make the National Integrity Systems more effective and sustainable.

The concept of the National Integrity System (NIS) has been developed and promoted by TI as part of its holistic approach to countering corruption. The NIS consists of the key institutions, laws and practices that contribute to integrity, transparency and accountability in a society.

The main ‘pillars’ of the NIS are considered to be the following:



Political Parties

Electoral Commissions

Supreme Audit



Public Sector

Police and Prosecutors

Public Procurement


Anti-corruption Agencies


Civil Society

Private Sector

Regional and Local Government

International Institutions

The NIS approach underpins many aspects of TI’s work, including much of the national and international advocacy undertaken by the TI movement. It also provides the conceptual basis for many TI publications, including the TI Source Book, the Anti-Corruption Handbook: National Integrity Systems in Practice and the NIS Country Study series.
