National Integrity System Assessment 2026 and beyond: Taking an Action-focused approach

By Derek Gill and Anne French
TINZ Directors

Transparency International New Zealand is revising its approach for ongoing revisions to the National Integrity System Assessment (NISA) 

The traditional NISA is structural in approach; equating institutions to “pillars'' that support a nation's integrity structure. TINZ’s Integrity Plus 2013 New Zealand National Integrity System Assessment using this methodology is 372 pages long. Its production spanned two years involving over 500 person-days of mostly volunteer time and expert knowledge.

The TINZ is moving away from a full National Integrity System Assessment (NISA) providing a pillar-by-pillar assessment to a more focused approach on priority interventions for change. This will not be a full format NISA as such but more a National Integrity System (NIS) action plan.

The first stage in this process is the release of a Gap Analysis which pulls together into an integrated document existing TINZ material including the 2013 NIS, the 2018 NIS update, the research paper commissioned from Simon Chapple in 2024 and our submission to UNCAC in 2025

The next stage of the process is to engage\ with experts on the integrity systems in a synthesis process during 2026 to develop an expert consensus on the longer-term priorities with the aim of ‘influencing the influencers’. 

This will be a Delphi type process using electronic decision support software to encourage maximum possible engagement. We are grateful for the support of 1000minds who is partnering with us to provide the decision support software that will be used to engage participants.

TINZ members who are interested in finding out more about this project and/or are willing to assist in testing the beta version of the decision-support software please email admin@transparency.org.nz

In tandem with its NIS refresh, New Zealand will be taking part in the Transparency International I Pacific Corruption Barometer.  New Zealand was last included in a barometer in 2013. 

We plan on releasing the National Integrity System (NIS) action plan in mid-2027 in tandem with the results from the TI Corruption Barometer, These will highlight the priority areas for action under each of the pillars and functions in the table below.
