Crown tops up NLTF $1.476bn after scrapping 2027 fuel tax and RUC rise

The Coalition Government will top up the National Land Transport Fund by $1.476 billion over the forecast period after cancelling the 12 cents-per-litre fuel excise duty increase and matching road user charge rises planned for 1 January 2027.

Finance Minister Nicola Willis and Transport Minister Chris Bishop announced the decision on 31 August 2026. Petrol fuel excise and equivalent RUC will next rise on 1 January 2028, but by 5 cents a litre rather than the previous one-off 12-cent step.

Three further 5-cent increases will follow at six-month intervals through the end of 2029. Annual 5-cent rises resume from 1 January 2030. Matching RUC changes apply at the same intervals.

The NLTF is principally funded by petrol fuel excise and diesel RUC. Freezing the 2027 step cuts hypothecated inflows unless the Crown replaces them. Ministers chose a general-taxation top-up rather than cutting the land-transport programme.

Bishop said Ministers had agreed to top up the fund for the reduction in fuel excise revenue, at an expected cost of $1.476 billion over the forecast period. Without that support, officials advised that large cuts to road maintenance, public transport and infrastructure would not be credible.

On that basis, Ministers have agreed to top up the National Land Transport Fund to account for the reduction in fuel excise revenue. This is expected to cost $1.476 billion over the forecast period.

Part of the cost will come from the $450 million Fuel Response Contingency established in Budget 2026. The remainder will be managed through, and shown in, the Pre-election Economic and Fiscal Update.

Willis tied the package to the fiscal strategy. She said New Zealand could afford the change because careful management had the country on track to return to surplus in 2028/29, earlier than forecast last year.

Cancelling next year’s planned fuel tax increases is the responsible choice. New Zealand can only afford to do this because of our Government’s careful management of the finances, which has ensured the country is on track to return to surplus in 2028/29, earlier than forecast last year.

The move converts what would have been user-charge revenue into taxpayer grant support for Waka Kotahi’s National Land Transport Programme. That softens the classical user-pays model for the affected years and places the incidence on the wider tax base.

Bishop said average transport project costs had risen by as much as 45 per cent since 2020 while fuel excise stayed frozen, falling about 20 per cent in real terms. He argued further indefinite freezes would undermine the system’s financial foundations.

Households and diesel fleets avoid the 2027 12-cent petrol step and matching RUC lift for one more year. Pump prices embed fuel excise plus GST on the duty-inclusive price; cancelling the step keeps that wedge out of 2027 retail prices. Freight operators face the equivalent through RUC rate cards.

Labour has pledged a three-year freeze on fuel excise and RUC. Bishop said that path would leave about a $4.6 billion hole in the NLTF. Labour leader Chris Hipkins disputed that figure and accused the Government of turning the Budget 2026 contingency into election-year funding.

Hipkins said National still planned cumulative 20 cents-a-litre rises from 2028 and argued now was not the time to lift petrol costs. The Government rejected Labour’s freeze as unsustainable against network need under the Government Policy Statement on land transport 2024.

Fuel excise was scheduled to resume annual increases starting with a 12c per litre increase from 1 January 2027, with equivalent increases to road user charges. That has now been scrapped, with the next increase of 5c a litre now taking effect from 1 January 2028.

Treasury will need to re-base FED/RUC and grant tracks in PREFU. NZ Transport Agency Waka Kotahi must reset NLTF cash-flow assumptions so multi-year maintenance and state-highway programmes under GPS 2024 are not scaled pound-for-pound with lost user revenue.

The $450 million contingency was originally framed for temporary, targeted responses if Middle East conflict drove further fuel spikes. Using it partly to fund a structural rate-path change reduces headroom for a pure temporary excise cut if crude prices surge again.

Fuel excise has not risen since 2020. Long-run migration of the light fleet from petrol FED toward distance-based RUC, including EVs, continues to shrink the traditional excise base. Delaying rate catch-up while that shift proceeds increases pressure for higher future RUC, a broader base, or ongoing Crown subsidy.

PREFU tables will show whether the $1.476 billion profile is multi-year operating funding to Vote Transport and how it sits against OBEGAL and net debt. Willis says surplus in 2028/29 and debt-reduction targets remain intact; the forecast update is the test of that claim.

For 2027, motorists and truckers get a full year without the scheduled hike while the Crown funds the gap. From January 2028 the 5-cent ladder begins. Whether that path holds, or faces another election-year rewrite, will determine how durable the shift from user-pays to taxpayer-funded roads proves to be.
