Port Nelson posted an underlying net profit after tax of NZ$12.7 million for the year ended June 30, 2026, on revenue of NZ$96.3 million — 15% ahead of the prior year — but a NZ$51 million asset write-down pushed the New Zealand port to a total comprehensive loss of NZ$31.5 million.

The board has declared a NZ$6.5 million dividend to shareholder IHL, the holding company owned by the Nelson City and Tasman District Councils, underlining that cash generation remains intact despite the accounting hit.

Cargo throughput reached 3.8 million tonnes for the year. The standout driver was a 66% surge in log exports, a direct consequence of the 2025 windthrow events that flushed storm-damaged timber through the supply chain ahead of schedule. Wine, fertiliser and kiwifruit volumes also performed solidly. Softer apple and sawn timber volumes offset part of those gains.

The revaluation is the more consequential signal for shippers and carriers calling at the top-of-the-south port. The NZ$51 million reduction in the carrying value of port assets reflects an expected decline in future cargo volumes — most notably the normalisation of log volumes once the early harvest of windthrow timber works through the system. Higher-than-expected capital expenditure on the completed slipway redevelopment at Calwell also fed into the write-down.

Chair Jon Safey moved quickly to contain any read-across to operations, emphasising that the revaluation "does not affect day-to-day operations, cashflow or the port's ability to continue investing in its infrastructure and the region."

That message matters for regional exporters. Forestry has been the swing volume at Nelson, and the windthrow recovery pulled forward demand that will not repeat. Chief Executive Matt McDonald was blunt about the trajectory: cargo volumes and underlying profitability are expected to fall from current levels as forestry volumes normalise and economic conditions stay uncertain.

McDonald is pinning the medium-term story on diversification rather than commodity cargo cycles. Continued growth in QuayConnect, the port's logistics and freight arm, the redeveloped Calwell marine haul-out and maintenance facility, and the commercial property portfolio are the pillars he says will "build a more resilient and diversified business over the long term," alongside continued investment in safety and operational capability.

The Calwell facility has already drawn strong demand since opening, giving the port a revenue line less exposed to bulk cargo swings. The year also delivered a 44% reduction in Scope 1 and 2 emissions against the FY2019 baseline and a major overhaul of the port's critical risk safety programme.

For forwarders and carriers serving the Nelson and Tasman regions, the numbers sketch a clear arc. FY2026 was an exceptional, weather-driven peak in log throughput — the 66% export jump was a one-off redistribution of harvest, not structural demand growth. Capacity planning on the Nelson trade should assume lower log volumes from FY2027, with the port's revenue mix shifting toward marine services, property and logistics.

The dividend declaration alongside a paper loss signals the councils' owner is prioritising returns and continued capital investment over balance sheet optics. With McDonald guiding volumes and profitability lower as forestry normalises, the test for Port Nelson will be whether QuayConnect and Calwell can grow fast enough to plug the gap left by windthrow logs.
