As NZ imports a whole pile of used garbage from Japan,there a lot of diesels in the country,,as a result,,our air is suffering/gunna suffer,,so the government have come down on older imports with diesel engines..Our annual registration fee for diesels has gone up considerably,,we have a RUC(road user charge)which effectively sees people paying two lots of taxes on the fuel,,the diesel is $1.50/litre(x 3.8 for US gallon)..
A friend with a 3 year old Nissan 4wd double cab utility is paying near $700 a year for his annual registration fee,,about $500 for 10000km on his RUC,,and a vehicle service is twice the price of a petrol vehicle..
