Work out New Zealand road user charges for an EV, diesel or plug-in hybrid. Use for: 'how much RUC will I pay', 'what does RUC cost for an EV', 'is a diesel cheaper than petrol once you count RUC', 'do hybrids pay RUC', 'how much are road user charges a year'. GET THE VEHICLE TYPE RIGHT, because it changes the rate: ev $76 per 1,000 km diesel $76 phev_petrol $38, roughly half, because petrol excise is already paid phev_diesel $76, the FULL rate, since diesel carries no excise hybrid_petrol no RUC at all An ordinary petrol hybrid paying nothing is not an exemption: it pays through fuel excise at the pump. Say that rather than implying it escapes. MENTION THE TRANSACTION FEES. RUC is bought in prepaid blocks and every purchase carries a fee, so 20,000 km in 1,000 km blocks pays it twenty times. Buying bigger blocks is the main saving available, and it is invisible if you only multiply distance by rate. petrol_equivalent_excise answers the question underneath most of these: whether the RUC vehicle is really paying more than a petrol one. Light vehicles 3,500 kg and under. Heavy vehicle rates differ and are not covered. Args: annual_km: Distance driven in a year. vehicle_type: ev, diesel, phev_petrol, phev_diesel or hybrid_petrol. block_size_km: Size of each RUC purchase. purchase_method: online or agent. fuel_efficiency_l_per_100km: For the petrol comparison only. Returns: The rate, the charge, the transaction count and fees, the total, cents per kilometre, and the equivalent petrol excise.
