The Board of Directors of KiwiRail is appointed by the Shareholding Ministers and KiwiRail’s performance is accountable to those Ministers. The Shareholding Ministers may jointly remove directors at any time and entirely at their discretion.

The role of the Board is to guide the strategic direction of KiwiRail and to direct and oversee management of the organisation.

The Board establishes objectives and sets strategies for KiwiRail, then monitors the performance of KiwiRail’s executive team against those strategies. The Board delegates the day–to–day management of KiwiRail to the Chief Executive.

Typically the Board meets once a month, and board directors also form sub-committees covering Health & Safety, the Environment, Assets and Infrastructure, and Property.
