The Green Party can be excused a great deal of self-congratulation at the weekend. With 11 per cent of the vote at the election it has confirmed its place as the third party in New Zealand, the only "minor" party to have consistently cleared the 5 per cent threshold. It has never relied on a single personality or an electorate provided by a major party.
All of its original MPs have now retired and its second leading duo is well established. The Greens have a settled national constituency though it may be going too far to claim, as co-leader Metiria Turei did, that the party does not prosper at Labour's expense.
At any election where one of the major parties is given little chance of winning, some of its usual voters will go to an alternative on its side of politics. The Greens will struggle to do as well at the next election with Labour under new leadership and the Government three years older. But the Greens will be there and bidding for a role that has eluded them so far, to be part of a government.
Ms Turei's speech contained an intriguing reference to that role. "We are not Labour's little brother," she said. "This is not about tuakana-teina, this is a relationship of equals. We will be a sizeable part of a future progressive government, an equal player."
The Greens have watched from the sidelines as other third parties have made pacts with a major party in power and in every case so far it has proved to be a fatal embrace. None have survived like the Greens, who have managed to get several programmes adopted by the previous Government and the present one while keeping their distance. They claim credit for subsidised home insulation, cycleways, identification of toxic sites and attempts to improve pest control on conservation land.
