So I think that we're in a very heightened and somewhat unusual period of politics and polling around the countries that New Zealanders take close interest in.

Politicians, no matter who they are, shouldn't be able to manipulate the public on a single issue and then call an election at the height of support - that's a little bit of a manipulation of democracy.

I'm much more attracted personally to governments going their full term. It's very hard to have a fixed term election I know with ah... a parliamentary democracy, but I've always had an instinct to say there should be a fixed term.

I mean you really can target your answers to get the instant response and I think that is a very manipulative type of polling. I really have no time for that worm at all.

I think we have a fascinating new and quite dominant input into politics - and it wont go away. From time to time, people articulate a view that we should ban opinion polls, but that's nonsense.

And if you're getting a poll coming out month after month saying something and then all of a sudden does an enormous swing in one direction - you are dealing with a more volatile electorate than most people believe they have.
