An exclusion zone is in place around the KiwiRail yard, while cordons are around the entrance to the wharf.
Fire and Emergency have been called to identify a substance that’s leaked, how much, and what the best course of action is.
A number of crews are on site - including a Hazmat truck.
The issue was detected in the yard around 2am, as a container was about to be transferred to a ship.
More to come.
