Until recently New Zealand was widely regarded as the least corrupt country in the world. But it has taken a tumble to number four on the just-announced Transparency International Corruption Perception Index. And the country's corruption-free score out of 100 has fallen three points from 91 to 88. So does this mean we're becoming more corrupt? And how do we explain the tarnishing of New Zealand's clean reputation?
It could be that many of the National Government's various controversies are finally coming to home to roost, impacting on New Zealand's global reputation. Although these controversies have varied in their seriousness and credibility, many of them have played a role in eroding the perceived integrity of the administration and the wider public sector.
For the most part, the various scandals have appeared to do no harm to National's popularity. But amongst the more politically engaged - as well as an international audience - some might well have finally been registered as stains on New Zealand's democratic credentials.
Measuring transparency and corruption
Today's report could be seen as delayed reaction or payback for years of eroding integrity. The latest report covers a two-year period up until mid-2015. Therefore it's the first annual Transparency International Corruption Perception Index to take account of the scandals involved in the 2014 general election - especially Nicky Hager's Dirty Politics, and the other controversies involving the then Minister of Justice, Judith Collins.
To arrive at New Zealand's reduced score of 88 out of 100, Transparency International has aggregated seven separate annual assessments by independent agencies such as the World Bank and the World Justice Project. All seven assessments provide a score out of 100 on governance issues (which are 92, 93, 81, 83, 98, 88, 83). In comparison to New Zealand's score of 88, three Nordic countries have registered higher scores (Denmark 91, Finland 90, and Sweden 89). This is why New Zealand is now behind them all, in fourth place.
The Corruption Perception Index has been in existence since 1995, during which time New Zealand has always been near the top of the table. In fact for the eight years from 2006 to 2013, we were right at the top. It was only last year that New Zealand was knocked off its perch by Denmark.
Unfortunately the new Corruption Perception Index doesn't provide any commentary on New Zealand's decline, and there is little available information about our new position. Many of the contributing assessments are not public either, which means we don't know why some of their scores have dropped for New Zealand.
Fortunately, however, the World Justice Project Rule of Law index is freely available. For example, according to this, the score for "no corruption in legislature" has dropped from 92 in 2014 to 86 in 2015. And perhaps of most concern, New Zealand dropped from 3 to 6 in terms of "Absence of Corruption".
