Benefits of shipping:
Resilience for natural disasters or emergencies.
Ships carry hazardous / dangerous cargo more safely than road, rail and air.
15% of New Zealand's inter-regional freight is carried by sea
Ships can handle oversized, heavy and bulky cargo that road, rail and air can't.
Freight volumes are forecast to increase 50% by 2040.
It won't all fit onto our roads!
New Zealand’s total freight task: 278.7 million tonnes.
Coastal shipping carries approx 10 million tonnes (3.5%).
1.15m people are transported across the Cook Strait every year
The volume of domestic freight moved by shipping has increased 50% over the last 10 years.
Approx $28 billion road and rail freight is shipped between the North and South Islands each year
1 standard container Auckland to Christchurch:
road: $2200-$3000
rail: $1300 - $1900
ship: $850 - $1300
418,470 containers are moved around the NZ coast per annum
Shipping: one-eighth the emissions of road per tonne of freight moved
Benefits of shipping:
Lower emissions per tonne of freight moved.
Increasing total freight carried by ship by just 2% would reduce total transport emissions by 16%.
Benefits of shipping:
Greater control over our domestic supply chains.
Shipping: 60% the emissions of rail per tonne of freight moved

Evaluating the opportunity to transition to a low carbon freight transport system (2023)

This document is independent research commissioned by Swire Shipping and conducted by the Electric Power Engineering Centre at the University of Canterbury, evaluating the opportunity to engineer transition to a low carbon freight transport system in New Zealand.

The research includes analysis of New Zealand-specific emissions by key commodities, with energy use and greenhouse gas emissions estimated across all freight transportation modes (Road, Rail, and Coastal Shipping).

Considering all the emission sources investigated, the research finds that road emissions are between 2.4 and 2.7 times higher than rail, and between 5 and 5.6 times larger than coastal shipping emissions.

The research finds that a shift of inter-island “general” road freight movements to coastal shipping can potentially increase ship utilisation from 70% to 90%, leading to an annual reduction of 161.7 kt CO2, which represents approximately 5.1% of direct heavy freight carbon emissions.
