Northport Ltd is the port operating company for the port of Marsden Point. Jointly owned by Northland Port Corporation and Port of Tauranga on a 50/50 basis, it is developing a deep water general/bulk cargo facility at Marsden Point.

With ever increasing cargo volumes coming out of Northland and Port Whangarei unable to handle the large volumes of timber exports expected, the decision was made in 1995 to commence development at Marsden Point when resource management applications were made. Development of the new port is on-going with the first two berths operational in June 2002.

Having obtained Resource Consents for construction of two additional berths in late 2004, Northport has commenced and completed construction of a third berth. With the third berth completed all remaining business at Port Whangarei was transfered to Marsden Point in April 2007. Construction of the fourth berth will take place when increasing port volumes attain viable levels.
