Using the ONRC, local authorities and NZ Transport Agency can compare the state of roads across the country, and direct investment where it is needed most. Road users will see an increase in the quality of some roads, and a decrease in others that have been over-specified in the past. Overall, New Zealanders will get the right level of road infrastructure where it is needed, determined by a robust, impartial, nationally consistent tool – the ONRC.
