Supply chains: New Zealand’s hidden infrastructure

We have seen that repeatedly. COVID-19 disrupted global freight networks, severe weather exposed weak domestic links, and the current Middle East conflict has forced an active government response to fuel security risks flowing through the Strait of Hormuz. In a country as distant from major suppliers and customers as New Zealand, supply chain disruption translates quickly into higher costs, constrained exports, delayed investment and weaker confidence. Supply chains are economic infrastructure, and when they fail, the impacts are economy‑wide.

The economic case is simple. Supply chains underpin both our economy and the wellbeing of our people. When they work well, businesses can secure inputs, exporters can reach markets, costs stay lower, and investment decisions are easier to make. When they don’t, the effects spread quickly through fuel, farm inputs, freight capacity, prices, working capital and confidence. For a remote island nation, this is not a niche logistics issue – it goes to the core of our productivity, resilience and growth. The Government’s own freight strategy makes the point clearly: the freight and supply chain system underpins New Zealand’s economy, international trade accounts for about 60% of economic activity, and around 99% of traded goods by weight move through our ports.

But the story is not all good. We have seen time and again that New Zealand is less able than it should be to absorb and respond to disruption; part of that reflects geography, some of it reflects the structure of a small trading economy, but the rest reflects choices. We have underinvested in some of the physical, digital and policy settings that would make supply chains more resilient, more visible and more adaptable. We have also been slow to follow through on work already identified as important. The issue is now whether we’re prepared to act on the problem. New Zealand already has a credible blueprint in the 2023 Aotearoa New Zealand Freight and Supply Chain Strategy, but what has been missing is sustained execution.

Government has a critical role here. Markets are essential, and the private sector makes most day-to-day freight decisions, but Government is uniquely placed to take the long view across the whole system – aligning policy, investing in cornerstone infrastructure, coordinating across agencies and crowding in private capital. That kind of stewardship counts even more in a country where long supply lines are part of the economic model, not an occasional inconvenience. New Zealand does not exist in isolation. We rely on open shipping lanes, reliable fuel flows, secure access to industrial inputs, and internationally competitive freight services. When those foundations weaken, the effects do not stay confined to the transport sector – they run through the entire economy.

Business also has responsibilities, and it should not wait for government to do everything. Firms need to invest, not just for today’s efficiency but for tomorrow’s resilience: better visibility across their supply chains, stronger planning, more diverse sourcing, and deeper capability to respond when disruption hits. Resilience, data sharing, capability building and emissions reduction all require business leadership as well as public policy. Visibility is not action though. Better information and sharper risk signals only count if they translate into practical decisions and real investment. That means moving beyond visibility dashboards to decisions on inventory buffers, supplier diversification and contingency planning.

Budget 2026 should send three clear signals:

• Commit to a targeted, multi‑year programme for nationally significant freight corridors, port connections and intermodal resilience.
• Build a national freight data and supply chain visibility capability to support better investment decisions and faster disruption response, building on the refresh of the National Freight Demand Study currently underway.
• Strengthen economic resilience through a focused package on fuel security, international freight preparedness and critical imports, and further investments in fuel diversification and emissions reduction.
  

None of this requires Government to do everything, or to spend without discipline, but it does require Government to do the few things only it can do: back nationally significant freight links, build better visibility across the system, and harden the economy against foreseeable shocks. In an election year, fiscal restraint is understandable; drift is not.

For a trading nation at the far edge of the world, supply chains are not background infrastructure. They sit underneath exports, investment, business confidence and the cost of living. We have been warned often enough. Budget 2026 is an opportunity to treat supply chains not as a risk to be managed, but as infrastructure that can underpin New Zealand’s next phase of growth.
