The most recent Roy Morgan was good news for the left:
Today’s New Zealand Roy Morgan Poll shows a substantial fall in support for Prime Minister John Key’s National Party to 40.5% (down 3.5% since March 11-24, 2013). Support for Key’s Coalition partners shows the Maori Party 2% (down 0.5%), ACT NZ 0.5% (unchanged) and United Future 0.5% (down 0.5%).
Support for Labour is 35.5% (up 1%); Greens are 13.5% (up 0.5%), New Zealand First 5% (up 2%), Mana Party 0.5% (unchanged), Conservative Party of NZ 1.5% (up 0.5%) and Others 0.5% (up 0.5%).
If a National Election were held today this New Zealand Roy Morgan Poll shows that the Labour Party with minor party support would win an Election if held now.
Vernon Small, who seems to be well informed, commented:
The numbers for the three biggest party are in line with internal polling by Labour, a source said. But the party has been reluctant to publicly release the data, waiting first to see it the shift away from National is confirmed by two polls expected this weekend from TV3 and TVNZ.
Tonight the TVNZ Colmar Brunton poll is roughly consistent with the Roy Morgan, but the TV3 Reid poll (no link yet and I’m off – someone add it in comments) paints a different picture. They can’t both be right (I think one of them is from planet Key).
Given that Roy Morgan and TVNZ (and if Small is correct internal polling) are compatible, I’m going to call the 3 News poll a rogue. (No doubt the political right will be trying to spin it the other way – I’ll be interested to see them try it!)
Note that sampling for these polls means that none of them will yet reflect any response to the Labour / Green electricity reform proposals.
