These suburbs were located on the edge of the city at the time where land was cheap and plentiful and where unique ideas about social and urban design could be implemented.
Overtime, these areas have been surrounded by private housing and merged into the Auckland conurbation. Two well known state housing areas are Otara and Glen Innes.
In the 1950s and 1960s the government directly marketed New Zealand to people in the Pacific. This was done so the new factories would have enough workers.
These migrants were often housed in the state housing areas close to the factories. Around 70% of migrants to New Zealand live in Auckland.
Today, houses in these areas cost a lot of money compared to other places in New Zealand, but within Auckland they are still relatively affordable. The houses themselves lend themselves to gentrification as they were very well built and can adapted to modern tastes
Ponsonby and Herne Bay used to be less desirable areas prior to the 1960's and the areas small cottages provided relatively cheap housing for working-class families, especially those who had migrated to Auckland from the Pacific Islands.
One of Auckland's original and largest industrial areas is Penrose. It is located on the narrow neck of land (isthmus), between the Manukau Harbour and the Hauraki Gulf.
This area of land is only 500m wide, so the Main Trunk Line (railway) and the Southern Motorway are forced to run through it. There is also a small port facility at Onehunga.
Many major industrial corporations are located in Penrose, such as Fletcher Building, Toshiba, Tip-Top etc.
Auckland Airport is the gateway to New Zealand for both passengers and freight. Many travel and transport related businesses have located near the airport to take advantage of the proximity to the airport and the passenger and cargo flows that it generates.
Travel businesses like rental car companies, motels, tourist attractions, retail and convenience food outlets line the streets near the international and domestic terminals to cater for the needs of the passengers who are arriving and departing, but also for the people that might be dropping them off or picking them up.
Other businesses have set up within a short taxi ride of the airport to cater for functions that draw people from around the country, e.g., business conferences and weddings.
Businesses that perform services for the aviation industry, e.g. plane maintenance, catering and cleaning are located on the airport grounds or close to it.
One of the best examples of agglomeration near the airport is the large number of logistics and delivery firms that have been established adjacent to George Bolt Memorial Drive. These business co-ordinate the global delivery of products, parcels and mail. Their location near the airport and along the main road back to the CBD speeds up processing and delivery of items.
Since the 1990's, apartment living has become a popular option in Auckland. Many people like an urban lifestyle where they are close to their workplace, shopping and entertainment facilities. It is also a popular option for busy professional workers that do not want to spend leisure time maintaining a house or a garden.
Inner city apartments form the main type of accommodation for Auckland's tertiary students. Auckland University is in the heart of the city and most students live in rented apartments.
Altogether, around 20,000 people live permanently in the CBD. Facilities such as laundries, convenience stores and even a 'metro' supermarket cater for these people.
Apartments are a relatively affordable option compared to buying a full house and property close to the city.
