…the New Zealand FOI regime probably fares the best, given its progressive openness and high level of political and official support, sustained by a wider pluralistic culture. The UK follows New Zealand, with reasonably high rates of disclosure, a strong Information Commissioner, single use of the veto, and some explicit political support. Third is Ireland and fourth Australia, both of which, despite high levels of use and disclosure, suffer from a high level of appeals, a lack of political support and consequent restrictive reform. Canada comes last as it has continually suffered from a combination of low use, low political support and a weak Information Commissioner since its inception.
