A container ship's horn sounding an emergency signal from Port Nelson could be heard around the city this morning.
However, the fire alarm at about 11.15am turned out to be because of a fault, said harbourmaster Dave Duncan.
The international emergency signal of seven short blasts and one long blast was given from the Spirit of Endurance berthed at the port.
Mr Duncan said the fault was being investigated.
