Results to OIA re Road User Charges.

OIA “seeking recorded information relating to the legal status, vesting, funding, and accountability of roads in New Zealand”

Outcome

The OIA was a partial win, not a full release.

MCERT identified 31 documents in scope. It released or linked some material, but most of the final bundle was partly withheld. One key document, Document 14: “Fleetwide transition to RUC – Cabinet paper” dated 17 January 2025, was withheld in full under section 9(2)(f)(iv), meaning the Ministry says it is still part of active government decision-making.

After the follow-up, MCERT also admitted that one withholding label in Document 9 was wrong. It had used s 9(2)(g)(i), but on 20 August 2026 it confirmed this was an administrative error and should have been s 9(2)(f)(iv). On 24 August 2026, it said the error has been recorded and the formal document updated for any future publication.

MCERT reconsidered Document 14 after the 14 August challenge, but kept it withheld. It says it considered whether factual/background/admin material could be released, but decided the whole document remains tied to live policy consideration. It also says there is no set date for a decision.

What We Learned

The released material is useful because it shows the Government’s own officials recognise problems in the transport funding system:

FED, RUC and motor vehicle licensing/registration revenue are hypothecated into the National Land Transport Fund, but that does not mean all transport funding is simple, transparent, or only from that fund.

Officials acknowledge that Crown funding outside the NLTF has increased, including separate programmes and top-ups. That makes planning, trade-offs and accountability harder.

The current revenue model is described as under pressure. Officials note New Zealand is unusually reliant on motorists and user charges, while existing sources are becoming less sustainable.

The move from fuel excise duty to RUC is being justified on fairness, sustainability, and future charging ability. One paper says FED under-recovers by about $300 million per year compared with light RUC.

Moving light vehicles to RUC does not itself create new revenue. It mainly creates the platform for more detailed charging, including possible distance, time, location, congestion or network-use pricing.

Officials recognise equity and fairness concerns, including that transport charges can be regressive and can affect people differently depending on income, location, vehicle type, and travel needs.

Tolling is limited in what it can fund: toll revenue is tied to the tolled road. The documents also recognise tolling has high administration costs and current tolling policy is under strain.

Officials have considered greater transparency, accountability, and possible consolidation of transport funding streams into the NLTF.

Bottom Line

This OIA does not prove by itself that the transport charging system is unlawful. But it does give strong evidence that officials know the system is fragmented, increasingly dependent on multiple charges and Crown top-ups, and has unresolved fairness and transparency problems.

The strongest unresolved issue is Document 14. That appears to be the key Cabinet-level paper on the fleetwide RUC transition. MCERT’s refusal, plus its admission of the redaction error, gives a reasonable basis for either an Ombudsman complaint or a later targeted OIA once decisions are made.
