Nelson Marina sits within Nelson Haven at the mouth of the Mahitahi (Maitai) River, sheltered by the Akersten Street reclamation and Port Nelson.

Its protected position provides berthage and vessel launching access to the recreational boating waters of Tasman Bay and the Marlborough Sounds beyond.

The marina's origins date to the early 1960s, when a 38-berth "Old Boat Harbour" was constructed on reclaimed land at the Dixon Basin.

Today the facility serves as a popular public destination, connecting Nelson city to the sea with waterfront space used by walkers and cyclists alike.
