An area of Napier Port has been cordoned off while firefighters deal with a chemical spill.
A small amount of sodium hydroxide, or caustic soda, has been found outside a container.
Three fire trucks, along with a combined hazardous materials unit and command centre were sent to the port at 8.20am.
Fire Service spokesman Mike Wanoa said there was no danger to the public because a secure area of the port was blocked off.
He said fire crews were decontaminating the area where the spill happened.
