Treasury advised the government not to buy rail enabled Cook Strait ferries three weeks before it announced it would.
On March 31 the government announced it would buy two new Interislander ferries to be delivered by 2029 to replace the current aging fleet.
It came in wake of Finance Minister Nicola Willis having pulled the plug on the previous government's Cook Strait mega ferry plan named iReX in 2023.
The ships announced in March would be 200 metres long and rail-enabled, which meant rail freight could be rolled on and off them.
New documents revealed under the Official Information Act show that just 20 days earlier, on March 10, Treasury recommended the government buy non-rail-enabled ships.
The agency said the option would be cheaper while achieving the aim of the project.
"There are operational advantages from rail-enablement, but these do not fully offset the increased capital cost."
The Ministry of Transport also cast doubt on the move, and last year a Ministerial Advisory Group recommended the government buy two non-rail-enabled ferries.
Meanwhile the Ferry Holdings Company which was set up in March to lead contractual negotiations with shipyards and ports supported a decision to buy rail-enabled ferries.
"The simplest and most efficient method of moving freight across Cook Strait is by rail-enabled ferries."
In a statement to RNZ Rail Minister Winston Peters said that officials took a narrow approach on the consideration of the ferry options.
"They were effectively on autopilot, believing the government would agree to end 60 years of Interislander connecting road and rail."
Peters said he did not agree with the advice Treasury provided.
"Their advice was so blinkered that it consistently presented its recommended solution as "cheaper" even when their own analysis showed the option we selected had the lowest overall cost and the highest economic value."
Treasury declined to comment on Peters' statements.

Taxes will have to increase to cope with ageing population, government spending
The IRD has warned government spending needs to change or taxes will need to increase in the future. Photo: RNZ Inland Revenue is warning that unless what the government spends its money on changes, taxes will need to increase in the coming years to cope with an ageing population. It is currently seeking submissions on its latest long-term insights briefing. It notes that in the coming years, if the current settings are maintained, government spending as a proportion of the economy will rise. "A core driver of these fiscal pressures is that New Zealand's population is ageing." By 2060, a quarter of the population will be older than 65. "This means that the amount the government needs to spend on superannuation and health care will increase if the government maintains current policy settings. "In its last Long-term Fiscal Statement, the Treasury predicted that government expenditure will exceed government revenue by 13.3 percent of GDP by 2061 if the government takes no response to rising fiscal pressures," IRD said. That would mean either that existing taxes would need to be levied at a higher rate - such as higher levels of income tax or GST - or there would need to be new taxes implemented. It said New Zealand taxed a more limited set of capital gains than most other OECD countries. It could be possible to broaden that scope. "The absence of a general approach to taxing capital gains can provide an incentive for individuals to reduce their tax liability by undertaking activities that are not taxed rather than those that are taxed. "This can reduce government's ability to raise more revenue in a way that is progressive." It pointed to an estimate for a Tax Working Group report in 2019 that, if a capital gains tax took effect from the 2022 tax year, it would raise about $3 billion in the 2026 tax year. Revenue would increase over time. IRD said this was in line with revenue raised in other countries from capital gains taxes. "Revenue from capital gains could therefore make a meaningful contribution to addressing long-term fiscal challenges. "However [as noted above] the last Treasury LTFS projected an operating deficit of 13.3 percent of GDP by 2061 under current settings. "Therefore, even with more comprehensive taxation of capital gains other tax or expenditure measures would be needed in the longer term. "Therefore, Inland Revenue considers that it is also important to consider how to increase the flexibility of the tax system to changing revenue needs." It said capital gains taxes could also have relatively high compliance costs. Inland Revenue said GST was a substantial source of tax revenue. But if it were to be increased, there would be concerns about the effect on lower-income households. While wealthier households pay more GST overall, poorer households spend more of their money on GST. IRD said GST could be applied at a lower rate on some goods and services that were bought by lower-income households, or there could be assistance via the welfare system to help those households. "Several international and New Zealand-focused studies have shown that using cash transfers is a more cost-effective way to target assistance to lower-income groups compared to applying lower rates to certain goods and services. "Several countries have implemented permanent GST-offset schemes for this reason." The report used modelling of GST at 18 percent. It also considered how other taxes such as payroll tax, wealth tax, inheritance tax, land and property tax could be used to add further tax bases to the New Zealand system. But it said there were difficult trade-offs with each of these. "Payroll taxes provide a means of shifting the balance of taxation away from capital income and onto labour income, but they are likely to have some disadvantages relative to GST and income tax. "Wealth taxes are likely to impose higher distortionary costs than a broad-based income tax, and they face similar challenges to those that would make an idealised income tax that includes accrued capital gains impractical. "Inheritance taxes are likely to have similar distortionary costs to income taxes when people are intentional donors, but they will have much lower distortionary costs when people are unintentional donors. "Land taxes are widely seen as one of the least distortive taxes, and they impose fewer distortionary costs than property taxes or stamp duties. "However, they would have a significant impact on certain groups. As with any tax, providing preferential tax treatment to certain groups or in certain situations would tend to increase efficiency costs and reduce horizontal equity on some margins." IRD said this underscored the importance of income tax and GST being designed in a way that was as efficient and fair as possible while having the flexibility to adjust to changing revenue needs. "New Zealand faces difficult choices in designing a durable tax system in the face of long-term fiscal challenges. "In Inland Revenue's view, a priority for future work should be on how to make New Zealand's main bases of income tax and consumption tax more flexible to changing revenue needs over time." It said, with different personal and company tax rates there was an incentive for people to "shelter" their income in companies. "This incentive is likely to increase the wider gap between top personal tax rates and the company rate, however, in the context of rising fiscal pressures, a system that requires alignment of the company rate and top personal rate is unlikely to be a durable tax system." Economist Shamubeel Eaqub said IRD had a clear message that either tax rates would need to increase, or the tax base - or both. "There are some difficult choices to be had in the future, if spending choices don't change then our revenue choices have to. "And we can either tax more using the same instruments that we have on the same bases that we have or we can increase the bases, and there are no easy answers. "There are always trade-offs, there will be winners and losers. And we're going to have to make a considered decision of what we're going to do - no tax is easy. "No one likes paying tax. I think it's about finding the least disruptive system given the public services that we want."
