The sequencing is backwards
New Zealand’s infrastructure agenda rests on a simple bet. Rather than raise fuel taxes to levels no government would survive taking to voters, the coalition wants tolling to help fund its Roads of National Significance. The problem is that the strategic plan meant to govern how tolling works as a system is now running two years late.
The national tolling plan was due in 2025. Waka Kotahi pushed it to 2026, then pushed it again to the first half of 2027. The agency’s explanation was blunt: it was “internal capacity constraints, resulting from the large volume of project-based tolling work that has been required in the past two years.” In plain terms, the agency has been so busy assessing individual toll roads that it has not had the bandwidth to write the plan meant to govern how all of them get assessed.
That is not a scheduling slip. It is a governance failure with a clear cost attached, and it is happening in the wrong order. The Land Transport (Revenue) Amendment Bill, which passed its second reading under urgency in June 2026, introduces corridor tolling, where an existing road can be tolled if users benefit from a new road built alongside it, and expands what toll revenue can pay for. The powers are moving through parliament faster than the framework that would tell decision-makers when and how to use them.
The funding hole is real and structural
The urgency is not manufactured. Fuel excise duty has fallen 21% in real terms since 2020 while construction costs climbed. NZTA’s Q2 2025/26 performance report shows Crown top-ups to the National Land Transport Fund are $542 million, or 37%, below budget year-to-date. Organic revenue from fuel excise and road user charges is $65 million above budget, nowhere near enough to close the Crown shortfall.
Tolling is not one option among several. The Infrastructure Commission has estimated that funding the RONS programme through existing levies alone would need a 70% increase in fuel excise and road user charges, a number no government would put in front of voters. The 2024-27 National Land Transport Plan forecasts $32.9 billion in managed funding, a 35% lift on the prior three years. The gap between what is forecast and what is actually committed is where the whole thing stalls.
Flagship roads in the slow lane
That gap has already claimed casualties. In early July 2026, NZTA released its Major Transport Projects Pipeline, and five flagship RONS were placed in a slow lane with no construction timeline. Transport Minister Chris Bishop conceded National’s 2023 commitments had been “very ambitious” and that circumstances had changed.
When RNZ asked Bishop whether his revised highway timeline accounted for the information gap created by having no tolling plan, he declined to respond, saying only that the minister had nothing to add beyond NZTA’s statements. That silence is telling. The law firm Hesketh Henry put the risk plainly on 13 July 2026, noting that deferring projects “can cost even more in the long run” as inflation drives up construction costs and delays the economic benefits the roads would generate.
The three toll roads that already exist
The model does work where the road is actually built. New Zealand’s three operating toll roads, all in the upper North Island, cleared 8.6 million, 4.1 million and 5 million trips across Northern Gateway, Tauranga Eastern Link and Takitimu Drive. Car tolls sit at $2.10 to $2.60, with truck tolls at $5.20 to $5.60. Of a $2.60 car toll, $1.46 repays debt, 80c covers operating costs and 34c is GST. It works, but slowly, and it works only where a road exists to toll. The Penlink stretch near Auckland, for one, has slipped from 2026 to 2029 with its cost past $830 million.
Why freight operators should worry
For businesses that move goods, the sequencing failure is the point. The National Road Carriers warned in submissions that the bill contains no mandatory upper limit on toll levels and no independent oversight, particularly where heavy vehicles have no practical alternative route. The industry body’s fear is that corridor tolling could “effectively convert many freight movements into compulsory tolled trips” if trucks are barred from the untolled alternative.
That is exactly the scenario a strategic framework is supposed to constrain. Expanded powers to toll are already law-in-waiting. The rules on how, when and how much are two years away. For freight-dependent operators, regional businesses and anyone waiting on a RONS corridor, the government has handed itself the tools before writing the manual, and the bill for that lands on the road users who cannot detour around it.
