Today, all funding for state highways and around 50% of funding for local roads comes directly from road users through the National Land Transport Fund. Road user revenue directed to the fund includes all fuel excise duty on LPG and CNG, around 55% of revenue from fuel excise duty on petrol, all revenue from road user charges (a prepaid distance/weight licence that all vehicles over 3.5 tonnes, and all non-petrol/LPG/CNG vehicles are liable to pay) and most non-ACC revenue from motor vehicle registration and licensing fees. In addition, in the last three years the government has increasingly allocated additional funds to land transport, to the extent that today the total expenditure by the NZ Transport Agency on land transport projects exceeds road tax revenue collected. The remainder of funding for local city and district roads primarily comes from local authority property rates.
