When the Kwun Tong reclamation project was completed in 1967, Ngau Tau Kok was the next to catch up. The following decade saw the reclamation of the remaining part of Kowloon Bay, a project that commenced on the two ends of the formation-to-be, one at Ngau Tau Kok and the other at the Kai Tak apron near Kowloon City. As the reclamation proceeded, the two sides got closer to each other until they became one, and the project was declared completed in the early 1980s. To remark, the fill material for this project came from Jordon Valley at Ngau Tau Kok, which was exploited since the 1970s, giving rise to Ping Shek Estate, the first to appear in the area, and other estates along Clear Water Bay Road, including Choi Wan Estate, Shun Lee Estate and Shun On Estate.

The order of Kowloon Bay today is partly the legacy of this reclamation, which produced the land area that embodied the Kai Tak apron area and cargo zone, Kowloon Bay Industrial Area, Kowloon Bay Cargo Working Areas and Ngau Tau Kok Industrial Area.

Accompanying the 1970s reclamation of Kowloon Bay was the extension of the new Kai Tak Runway. Completed in 1974, the extension lengthened the runway to 3,400 meters, allowing it to accommodate all kinds of wide-body aircraft.
