NZ First leader Winston Peters was personally involved in the decision as state-owned enterprises minister, the portfolio responsible for KiwiRail.
Today, he tried to pin the blame on Labour, arguing the problem had gone off the rails when he left the government in 2020.
“As you know, when I left [being] in charge of that operation, things were under control, and the moment I left the whole thing blew out completely,” Peters said.
He would not answer questions about whether he tried to save the project as National moved to kill it. Peters and the rest of the Government are currently working on salvaging the Scott Base redevelopment in Antarctica, which is also facing massive cost pressures.
Labour MPs noted one of the causes of the blowouts, the need to significantly upgrade portside infrastructure, was known to Peters. They cited a press release from the 2020 Budget in which Peters announced “$400 million to help replace the Interislander ferries and associated portside infrastructure”.
Another cause of the cost blowout was the decision to opt for rail-enabled ferries, rather than the more conventional ferries used now.
Peters said this was not a mistake.
Willis pinned the cost blowouts on the previous government. Former finance minister Grant Robertson called on her to release the documents behind the decision, showing the work the former government did to keep costs under control.
She said there was a “pattern of cost escalation that occurred with [the] project” while Robertson was its key shareholder.
Robertson said KiwiRail told ministers in October 2022 the “worst-case scenario” would see the tagged contingency for the project blow out by $280m. However, the cost of the project blew out by another $1b just months later, taking its total cost to $2.6b.
