ACT Party leader David Seymour is weighing into the growing debate over Auckland’s proposed second harbour crossing, as infrastructure spending becomes a major battleground heading towards the election.
Seymour follows New Zealand First leader Winston Peters into the Waatea studio at a time when political parties are rolling out policies and major spending commitments, with the future of Tāmaki Makaurau’s transport network emerging as one of the biggest questions.
At the centre of the debate is the proposed additional Waitematā Harbour crossing, a project that could become the most expensive infrastructure undertaking in New Zealand history.
The scale of the proposal presents politicians with three fundamental questions — whether New Zealand can afford to build it, who should pay, and whether Auckland can afford to continue without it.
Auckland’s population and transport demands are continuing to grow, placing increasing pressure on existing roads, public transport and the Auckland Harbour Bridge.
The existing bridge is also a critical piece of national infrastructure, meaning disruption can have consequences extending beyond commuters to businesses, freight movements and the wider economy.
Supporters of another crossing argue the debate therefore needs to consider resilience as well as congestion.
But building infrastructure on this scale comes with an enormous financial challenge.
Any future government would need to determine how much should come directly from taxpayers and how much should be recovered from Aucklanders and those using the new crossing.
Potential funding mechanisms could include tolls, congestion charges, road-user charges, borrowing, private investment or partnerships between government and commercial investors.
Those choices could become particularly important for ACT.
Seymour and his party have traditionally placed strong emphasis on disciplined government spending, value for taxpayers and greater use of user-pays principles, meaning a project potentially costing many billions of dollars presents a significant test of those priorities.
There is also a national fairness question.
Communities outside Auckland face their own infrastructure deficits, including ageing roads, hospitals, schools, water systems and regional transport connections.
Committing enormous amounts of public money to one project in Tāmaki Makaurau could therefore trigger debate about whether Auckland should contribute a greater share of the cost.
On the other hand, Auckland is the country’s largest city and a major engine of the national economy. Transport bottlenecks there can create economic costs that ultimately extend well beyond the region.
For Māori, any crossing would also need to involve more than engineering and economics.
The Waitematā is culturally significant, and a project of this magnitude would require meaningful engagement with mana whenua over impacts on wai, whenua, te taiao and sites of cultural significance.
Decisions about the crossing could shape Tāmaki Makaurau for generations, making the voices of mana whenua important in determining what infrastructure is built and how.
With the election approaching, the harbour crossing is becoming a useful test of competing political philosophies.
Most parties can recognise the need for better infrastructure. The harder argument begins when politicians have to explain how much they are prepared to spend, where the money will come from and who will ultimately pay it back.
For Seymour, that puts the second Waitematā crossing squarely at the intersection of ACT’s arguments about government spending, infrastructure, economic growth and personal responsibility.
And for voters, the choice may eventually come down to an equally difficult calculation — whether paying billions for another harbour crossing is too expensive, or whether another generation of congestion and delayed infrastructure would cost Aotearoa even more.
