Roy Morgan has a new poll out, and this graph shows the post-election National vs Greens/Labour vote. Basically Labour is gaining and the Greens are holding steady.
Maybe National are implementing unpopular policies now on the hope that they’ll pay off over three years, and they’ll be re-elected on the strength of an economic recovery. I think this is unlikely. Asset sales, welfare reform and public service cuts are happening because they have to – English is broke and boxed into a corner fiscally.
