Two of New Zealand’s biggest transport unions have expressed their concerns about decisions made around the emissions
footprint of new interisland ferries.
KiwiRail signed an agreement with a Korean shipyard in June to build two new Interisland ferries, expected to be
delivered in 2025/2026.
However, media reports have shown the most environmentally friendly options were passed up.
The new ferries will have lower emissions than current vessels, as they will be powered by a hybrid of marine diesel and
batteries, but questions have been asked as to why KiwiRail did not opt for methanol rather than marine diesel.
New and converted ships in Europe are already using methanol, which could reduce emissions even more.
Methanol is largely produced from natural gas, although renewable sources are becoming a potential source – the world’s
largest shipping operator, Maersk, already operate a ship on green renewable methanol, and have ordered another eight.
Maritime Union National Secretary Craig Harrison says there is a strong case for improving emissions in shipping and New
Zealand needed to be a world leader, not a follower.
“The key thing here is to build in security and reliability, on top of the necessary work to reduce emissions to meet
the Government’s own targets.”
Mr Harrison noted methanol was produced in New Zealand, whereas marine diesel would have to be imported when Marsden
Point refinery was taken offline.
Rail and Maritime Transport Union General Secretary Wayne Butson suggested the Government needed to review the decision.
“Part of the problem is how KiwiRail operates as a state-owned enterprise, so while the Government is pursuing good
goals to reduce emissions, SOE’s are still beholden to an outmoded model that undermines those goals.”
Mr Butson suggested a crown entity model would be appropriate for major Government owned enterprises such as KiwiRail or
in the electricity sector, to align with Government’s environmental and social goals.
