If there is on thing that the National Government has done is to force Government agencies into actually making evidence based policy and evidence based decisions. It's a weird thing, you would have though we (as a country) have been doing that for years, but we haven't. Even worse some of our parties "sell" policy options for votes, and don't care that it reinforces a particular hegemonic school of thought. And we get weird results from this lack of evidence based policy, teachers who don't believe dyslexia actually exists is one example.
The downside of this is that an enormous amount of effort now goes into gathering this evidence. This has always been the problem of the Public Service... everything must be accounted for, and the cost of the accounting means that the Public Service overall cannot be efficient.
The other downside is that an equally enormous effort now goes into hiding/disguising this evidence, to protect vested interests (people's jobs, power structures, Govt's reputation).
