Also the annual registration should relate to CO2 emissions as it does in the EU. The Dodge Ram mentioned above would probably be in the UK top rate for that, a cost of NZ$5,000 for the first year of registration and $1,000 per annum thereafter, approx.
I can't agree with that, as claimed fuel economy figures are mainly BS relative to real on-road economy (CO2 emission in Kg being a direct multiple of fuel use in litres).
If there's going to be such a carbon tax, then it should be on fuel. And if they're going to do that, then they should impose the same tax per CO2 equivalent emissions for everything - not just private motor cars which only account for a small percentage of NZ total emissions.
That would be very effective, as farming, manufacturing export industries would go out of business,we wouldn't be able to afford cars but could use hand tools make wooden bicycles to ride around on.
