New Zealand exports hit a record $8.9 billion in May 2026, an 18% jump from the year before. That sounds like a clean win for the economy. But for the businesses actually moving goods, the picture is more complicated. The freight and supply chain system underpins roughly 60% of New Zealand’s economic activity, and around 99% of traded goods by weight move through ports. When those ports slow down, or when fuel reserves sit offshore in other countries, the cost lands directly on the businesses trying to fulfil orders.

New Zealand businesses are operating in a strange moment. Export demand is climbing — goods exports surpassed NZD 80 billion for the first time in the year to December 2025, a 14% increase. Yet the infrastructure needed to move those goods is under strain, and the fuel to power that movement is mostly stored overseas. The gap between rising demand and fragile logistics is where most of the real headaches live. Here’s what you actually need to know.
When you hear “supply chain” in a New Zealand context, the first term worth understanding is ticket contracts.
What I tend to notice is that many business owners assume supply chain risk is about shipping delays. In New Zealand, it starts with whether the fuel to move those ships is even accessible. That distinction matters more than most people realise.
What happens when fuel and freight are both stretched
The most immediate consequence of a fragile supply chain is cost. When fuel reserves are held offshore and domestic stocks sit at just 38 days as of January, any disruption — a port closure, a shipping route issue, a spike in global oil prices — hits New Zealand businesses faster than it would competitors in countries with onshore reserves. The Treasury notes Middle East-related disruptions are expected to be temporary, but short-term impacts still translate into higher freight costs and delayed shipments.
For a business exporting dairy or meat, a two-week delay can mean missed shelf-life windows. For a business importing raw materials, a one-month fuel price spike can wipe out margins on orders placed three months earlier. The freight system underpins 60% of economic activity, but persistent underinvestment in physical and digital infrastructure limits how quickly the system can absorb shocks.
The compliance angle is less obvious but real. Businesses that rely on just-in-time inventory — common in retail, manufacturing, and construction — face a structural risk. If fuel supply tightens and shipping schedules become unpredictable, the cost of holding extra inventory rises. But the cost of not holding it can be worse: lost sales, broken contracts, and reputational damage. That trade-off is not theoretical. It is playing out now for businesses that depend on imported components or export perishable goods.
Where businesses get supply chain planning wrong
Treating fuel as someone else’s problem
Most businesses do not think about where their fuel comes from. They assume it will be there. But with nearly 60% of petroleum reserves held offshore and domestic stocks dropping, that assumption is risky. A business that depends on road freight to move goods to port is exposed to diesel price spikes and availability. The fix is not simple, but the first step is knowing your exposure. Map which legs of your supply chain rely on fuel-intensive transport and ask what happens if that fuel costs 30% more or is delayed by two weeks.
Ignoring the port bottleneck
Around 99% of traded goods by weight move through ports. If a port slows down, everything slows down. Many businesses treat port delays as a shipping company problem, but the cost lands on the consignee. Late penalties, storage fees, and lost customer goodwill add up. What I would do is build a buffer into delivery timelines — not just for shipping, but for port processing. A week of buffer on a 30-day lead time is cheaper than a rush order on air freight.
Overlooking the rail network gap
Budget 2026 allocated $1.073 billion to Kiwirail’s national rail network through the Rail Network Investment Programme 2027–2030. That is a significant commitment, but it follows years of underinvestment. Businesses that shifted freight from rail to road during that period may find it hard to switch back quickly. Rail is generally cheaper per tonne for bulk goods, but only if the network is reliable. If you ship bulk goods, it is worth checking whether rail is a viable alternative for at least part of your route — and whether the upcoming investment will improve service in your region.
Assuming ticket contracts cover emergencies
The government uses ticket contracts to claim oil stored in other countries. That works in normal conditions. During a major disruption — like closure of the Strait of Hormuz — those tickets may not be honoured or may be inaccessible. Recent agreements with Singapore aim to secure trade and fuel flows, but the structure remains fragile. Businesses that plan for a worst-case scenario where fuel is simply not available for a period will be better positioned than those that assume the system will hold.
Practical steps to strengthen your supply chain
Map your fuel dependency
Start with a simple exercise. List every leg of your supply chain that requires fuel — road freight, shipping, air cargo, rail. Estimate how much each leg costs and how much of that cost is fuel. If fuel prices rose 20%, which legs would hurt most? That tells you where to focus. For businesses with significant road freight, a fuel surcharge clause in contracts with carriers can help manage volatility. For businesses that ship internationally, understanding the fuel component of ocean freight rates is worth the time.
Diversify your transport modes
Relying on a single mode of transport is a risk. If road freight is your only option and diesel prices spike, you have no alternative. Rail, coastal shipping, and air freight each have different cost structures and fuel dependencies. The $1.073 billion rail investment suggests the government expects rail to play a larger role. If your goods are suitable for rail — bulk, non-perishable, heavy — it is worth exploring now rather than waiting until road costs force the switch.
Build inventory buffers strategically
Just-in-time inventory works when supply chains are predictable. New Zealand’s supply chain is not predictable in the same way as a land-connected economy. Holding extra inventory costs money, but so does a stockout. The trick is identifying which items are hardest to replace quickly. For imported components with long lead times, a buffer of four to six weeks may be worth the carrying cost. For locally sourced items, a shorter buffer is usually fine. The calculation changes if fuel disruptions become more frequent.
Watch the emerging market shift
New Zealand’s export growth is increasingly driven by emerging markets in Southeast Asia and South America. These markets are expanding imports of technology, pharmaceuticals, and environmental solutions. That shift reduces reliance on traditional markets, but it also introduces new logistics routes with different risks. Port infrastructure in some emerging markets is less developed. Customs processes vary. If you are expanding into these markets, factor in longer lead times and higher uncertainty rather than assuming the same reliability as established routes.

Prepare for the future-phase changes
The 2023 Aotearoa New Zealand Freight and Supply Chain Strategy recommended significant upgrades to physical, digital, and policy infrastructure. Budget 2026 starts addressing some of those gaps, but the strategy itself acknowledges that underinvestment has been persistent. Businesses should expect gradual improvements in rail and fuel resilience over the next three to five years, but not overnight fixes. The WTO also launched a revamped data portal to improve trade data access, which could help businesses track tariff actions and export patterns more effectively. That is worth bookmarking if you trade internationally.

Supply chain resilience is not a one-time fix
The record export numbers are a genuine achievement, but they sit on top of a logistics system that is more fragile than most businesses realise. Fuel reserves held offshore, a rail network recovering from years of underinvestment, and a port system that handles nearly all traded goods by weight — each of these is a vulnerability. The businesses that will manage best are the ones that treat supply chain planning as an ongoing process, not a box to tick. Map your dependencies, build realistic buffers, and watch the infrastructure investments that affect your routes.
