Port Otago Limited is located on the Otago Harbour, on the lower east coast of the South Island of New Zealand. Otago Harbour is world-renowned for its physical beauty and is regarded as the eco-tourism capital of New Zealand because of its abundant sea and bird life. Port Otago operates two wharf systems - Port Chalmers and Dunedin - within Otago Harbour.  Port Otago is the primary export port for the South Island region of New Zealand and believes strong competition offers real benefits to shipping lines and cargo owners. Within the entrance, the harbour extends 9.6 kilometres to Port Chalmers and then carries on a further 12 kilometres to the port and city of Dunedin.  The harbour is dredged to accommodate vessels with a draught of 12.5 metres, from Taiaroa Head to Port Chalmers, where the container facilities are located.  This draught enables the largest containers ships in the New Zealand trade to make Port Chalmers their final port of call in New Zealand.  From Port Chalmers to Dunedin the channel is dredged to handle vessels with a draught of 8.0 metres.
