So, are there Biofuels available in New Zealand?

I certainly can’t find any distributors of it Wellington and am beginning to get vexed. Apparently there are Gull outlets that sell it, there is one in Masterton but a journey (and energy expended) out there rather defeats the purpose of buying the energy efficient fuel. Well its time for me to stop, this wild biogoose chase but maybe you know, can you help me?
