A synthesis of reasoning, not a probability or recommendation.
The balance of the case is mixed.
Making public transport free in New Zealand could increase accessibility and reduce emissions, but existing pricing mechanisms, environmental costs, and mode favoritism concerns moderate support.

Strongest arguments
For
Removing fares eliminates a financial barrier, enabling more people, especially those with limited income, to use public transport for essential activities like work, education, and healthcare.
By incentivizing a shift from cars to public transport, free fares can decrease traffic congestion and pollution, supporting New Zealand’s climate goals.
Fare collection requires infrastructure and staff; removing fares can reduce operational complexity and improve boarding times, enhancing service efficiency.
It supports equal access to mobility regardless of income, helping to reduce social disparities and improve quality of life.
Lowering the cost barrier encourages more people to try and regularly use public transport, potentially leading to long-term modal shifts.
Removing the fare at the moment of travel changes the immediate choice environment, which may matter more than a cash payment that is mentally separated from the transport decision or not earmarked for mobility.
Against
Lost fare revenue must be replaced by public funds, which could require higher taxes or cuts to other services, raising sustainability concerns.
Increased demand without proportional investment in infrastructure and vehicles can degrade user experience and reliability.
Some users may shift to public transport, but others might not change habits significantly, limiting environmental benefits.
Without fare barriers, some individuals might use services excessively or inappropriately, potentially increasing maintenance and security costs.
Focusing resources on low-income or frequent users could achieve equity goals with less fiscal impact.
If the policy goal is to improve accessibility for low-income users, a cash payment lets recipients choose the transport option or other goods and services they value most, rather than prioritizing public transport over their preferences.
By making driving more expensive through these mechanisms, the externalities of car use are partially offset, potentially making free public transport less necessary or efficient.
Universal free fares could distort transport choices by privileging public transport, whereas a neutral policy would support all low-impact modes equally.
Energy use, infrastructure, and vehicle emissions mean public transport is not without environmental cost, which complicates claims of net environmental benefit.
If self-driving electric taxis or similar services become broadly competitive, then a bus-centered free-fare policy could lock in spending on a mode that is later outcompeted by more flexible and potentially lower-cost alternatives.

Free public transport under existing modal options risks driving investment in the wrong direction - motivations appear increasingly ideological. With the current trend of technology it seems extremely likely that self driving electric taxis on a ride-hailing type system will, in the near future, dominate all existing NZ public transport options from a convenience AND cost AND environmental impact perspective, with only the possible exception of light rail (which isn’t an option in most of New Zealand). Rather than embarking on a major new initiative likely to center on buses which will soon be redundant, we should focus investment on alternative transport modes and pedestrian friendly city centres which will complement future dynamic low cost ride hailing solutions.

Arguments around the equivalence of targeted payments miss the psychological impacts of free, and the compounding beneficial effects of mobility. Removing the marginal disincentive to move has greater benefit than just a moderate cash contribution enabling an individual to access similar mobility options.

To the extent that free public transport increases accessibility for low income groups, this is a case of a targeted subsidy that prioritises a certain class of outcome for low income groups over others that they may prefer. A superior option, which would also be more cost effective, would be an equivalent targeted payment to low income groups, which they could spend to either increase access to whichever their preferred transport option is, or any other good or service they valued more highly.

A better approach is simply a carbon tax on petrol, which we have, and paid parking, which we have and could increase. With these, driving is no worse than public transport because the externalities are offset. Making public transport free beyond that is unnecessary and furthermore it picks a winner whereas biking and walking are not favoured. The most efficient outcome is simply if all externalities are paid for, and we are actually reaching this status quo now. In a sense, this proposition also ignores that public transport has an environmental cost too.

Read the full analysis
The proposal to make public transport free in New Zealand is supported by arguments emphasizing increased accessibility for low-income populations, potential reductions in private vehicle use and associated emissions, and simplification of fare systems. However, concerns about the substantial fiscal burden on government budgets, the risk of overcrowding or reduced service quality without corresponding capacity increases, and uncertain behavioral responses temper enthusiasm. Additionally, existing policies like carbon taxes and paid parking internalize many driving externalities, potentially reducing the need for free public transport subsidies. The environmental impact of public transport itself and the issue of favoring one transport mode over others like biking and walking add further complexity. The overall score reflects a cautiously optimistic view that benefits could outweigh costs if implemented with adequate funding and planning, but significant uncertainties and alternative policy considerations remain about long-term sustainability and effectiveness.
Important facts
Fare revenue typically covers a minority of total public transport operating costs in New Zealand.
New Zealand public transport is already heavily subsidized by government funding.
Some New Zealand cities have trialed free public transport with mixed results on ridership and costs.
Shifting from private cars to public transport reduces per capita emissions if vehicles are well-utilized.
Uncertainties
Whether sustainable funding models can support free public transport nationwide.
How much free fares would increase ridership and reduce car use in New Zealand’s context.
Whether public transport infrastructure can handle increased demand without service degradation.
The broader social impacts, including potential misuse or changes in public perception.
How quickly autonomous electric ride-hailing could become a cheaper and more convenient alternative to conventional public transport in New Zealand, and whether that would materially change long-run investment priorities.
Assumptions
The government is willing and able to allocate sufficient funds to replace lost fare revenue and invest in capacity.
Users will respond positively to free fares by increasing public transport use and reducing car trips.
Public transport services will be expanded or improved to accommodate increased ridership.
