but around several discrete nuclei. On that note, smaller business district acts as satellite nodes, or nuclei, of activity around which land use pattern formed. This model based on the notion that central business district (CBD) was losing its dominate and primacy as the nucleus of urban areas. However, it differed from other two by its abandonment of the CBD as a sole focal point to the existence of number of discrete nuclei around which individual land uses were geared.

Freeway connecting town and Fly Over connecting airport which provide easy access to all main centers in the city. There are more offices for private and public sectors, shopping centres including vision city shopping mall, commercial buildings, banks, market, hotels and recreational and world class sporting avenues. The hill side of Waigani is surrounded by different classes of the residential housing market for high-income earners. Some are newly built, others are existing ones and redevelopment.
The suburbs of Morata, Rainbow, Erima, Taurama, Sabama, Tokarara, North Waigani, 5 mile,
8mile, 9mile and 14 mile are recently becoming the producers of more medium and high income residential housing stock for renting and owning in the city.
