Mr Øksnes says any decision to privatise the service or take rail from the Cook Strait would endanger Aotearoa’s economic and climate future.

“We have seen the impact of privatisation of this kind of lifeline service elsewhere in the world and it has inevitably come at great cost to freight customers and to the public.

“Just as significant is the threat that this would pose to rail in Aotearoa New Zealand. Rail produces 70% fewer emissions than road freight and losing that would make it harder to meet international climate obligations.

“There’s also the added cost and risk to any export company that uses rail as part of its domestic supply chain, as the total carbon content of imported goods is becoming more and more important to international consumers.

“The rest of the world is taking carbon out of their supply chains, so putting more in would be a backward step for Aotearoa New Zealand’s exporters.

ITF Maritime Policy Adviser Sadie Saunders, also in New Zealand this week, says “We understand the New Zealand government is concerned about cost, however transport infrastructure is a long term investment that ensures good jobs and efficient supply chains. These are projects that should be measured across decades and in the context of the whole economy.

“This is why we are supporting our Aotearoa New Zealand affiliate members’ calls for new ferries to be publicly owned and rail enabled.”

The International Transport Workers’ Federation (ITF) is a democratic, affiliate-led federation recognised as the world’s leading transport authority. It represents, and is democratically guided by, 16.5 million transport workers internationally.
