If the Greens are intent on becoming a mainstream political party with sufficient cachet to be a credible Government partner they should persuade Metiria Turei to join Russel Norman in resigning. Norman's resignation - announced with a great deal of dignity yesterday - has switched the focus to Turei.
Norman is by far the stronger of the two co-leaders. He is the one who publicly pulled the Greens back from the brink of being marginalised by running a far Left economic agenda instead of leveraging their valuable green political brand.
Norman led the change away from some of the more disruptive policies that neither the party's main prospective political partner Labour, nor National would really have a bar of. At the 2014 election the Greens did roll out some interesting policies particularly with innovation: 1000 new tertiary places for students of engineering, mathematics, computer science, and the physical sciences; $1 billion of new funding for R&D. They got it that innovation was "one of the best ways to add value to our exports, raise wages, and better protect the natural world we love".
And frankly this is an area where New Zealand still needs a great deal more focus and urgency. Unfortunately for Norman - and Turei - the policy changes came too late to build a groundswell of support. The Greens didn't achieve a strong enough focus on their own brand, instead wandering too much away from the centre line they need to occupy if they want to have an influence on a future government by getting into bed with either of the two main parties.
And there just hasn't been enough policy consistency in place for long enough for a new image to bed down.
