I'm starting this, as the EV threads have gone ridiculously off topic. And threads on power companies have previously done so as well.
What I want to see changed:
Get rid of the electricity low user regulations. As they make electricity more expensive than fossil fuels for lots of consumers. And make it difficult for power companies to give pricing incentives to reduce carbon emissions.
Get rid of the Resource Management Act. And replace it with separate simple laws regulating the environment and town planning. Laws that give simple yes / no answers as to what you can and cannot do. Instead of leaving everything to council bureaucrats and the courts.
Edited to add
Make petrol cars liable to pay RUC. As when EVs have to start paying RUC, certain petrol cars will end up paying less tax than EVs.
