Reclamation of Wellington Harbour means to build a new area where land has been reclaimed from the sea. Land reclamation is a process by which soil or sand is removed from one area and moved to another area to be filled in and built upon. In Wellington Harbour, this land was reclaimed and used to create new areas for businesses, homes, and recreation. When the land is reclaimed, the water is pushed back and the area is given a new purpose.
