The New Zealand Transport Agency / Waka Kotahi says it has not developed a national tolling plan but is working on a strategic network assessment.
On government orders, the agency will be using tolls more to pay for roads.
Internal documents in April said managers were going to develop a National Tolling Plan for the agency's board.
But Waka Kotahi, in a response to a request under the Official Information Act, said no plan existed, and instead it briefed the board last month about being more strategic.
"We are changing our tolling assessments to cater for a broader system network perspective... to provide decisionmakers with a more strategic, system-wide consideration of tolling the network," said the update in June.
It was doing tolling assessments of all dozen or so roads of national significance in the works, including the Northland corridor to Whangārei, Mill Road in west Auckland and Tauriko West near Tauranga.
"Due to data and modelling complexities associated with modelling tolling proposals for each section of the Northland Corridor, a proposal will be made to the board on the whole corridor" by the end of this year.
An expensive overhaul of tolling technology had been going on for several years, however, the national manager of system design told RNZ an update on tolling tech has not been presented to the board.
