Duncan Garner is a bit of a stirrer, but he pulled out some interesting numbers in his article yesterday arguing the Greens should move to the centre:

The Greens talk poverty and social justice, but the poor aren’t listening – and they’re certainly not voting for them. Look at these telling statistics from the poorest electorates in the country: In Manurewa, in the crucial party vote, just 868 people voted for the Greens; in Manukau, East it was just 744; in Mangere, it was just 865. Now look at the two most wealthy suburbs in NZ: In Epsom, the Greens got 3415 votes; in Wellington Central, they got 8627 party votes, more than Labour’s 7351; in Auckland Central the Greens got 4584 votes, compared to Labour’s 4758.

I would really want to see some more numbers around this, but if this is a general trend, then it would suggest either:

The Greens’ support is from the relatively well-off who care about the poor, rather than the poor themselves; or People who care about the environment tend to be relatively well-off.

Now I’m sure the make up of the Green support base isn’t that stark. But in the context of our discussion (e.g here, & here) about a centrist Green party, if the Greens moved to the centre they would likely lose group 1 but keep group 2.

The interesting question therefore is what proportion of their support base falls into both camps (i.e. care about social justice and the environment) and what weighting they place on both issues. This then follows on to the question of what is the untapped support base of people who care about the environment but generally vote National?
