If that is disappointing, it shouldn’t really be any surprise. The Green Party approach to immigration is pretty open – the “globalist” strand in their thought apparently outweighing either concern for New Zealand’s natural environment or any sort of hard-headed analysis of the economic costs and benefits to New Zealanders. Only a few months ago, they were at one with the New Zealand Initiative, tarring as “xenophobic” any serious debate around the appropriate rate of immigration to New Zealand. Never mind that population growth is driving up carbon and methane emissions, in a country where marginal abatement costs are larger than in other advanced economies, and yet where the same party is determined that New Zealand should reach net zero emissions only 33 years hence.
