Jobs could be on the line at KiwiRail as the state-owned enterprise confirms it is consulting on proposals for change.
KiwiRail has been dealing with multiple ferry failures, including the grounding of the Aratere last month and the Kaitaki losing power in 2023 with nearly 900 people on board.
Transport Minister Simeon Brown has raised serious concerns about its fleet maintenance.
KiwiRail's chief people and communications officer Andrew Norton said the changes were only proposals at this stage.
"Our transformation programme is underway, and at this stage we are in the process of consulting on proposals for change in some corporate areas," he said.
"As these are proposals only it is not possible to comment on the number of roles that will be affected until we have completed our consultation processes."
