The success of the plan can easily be guessed by having a look on the rapid growth rate of business opportunities in the city . Many such areas which were not attractive for the business investments are now being considered as desirable ones because of the development of transport and housing sector. If the thirty year duration of Aukland plan is considered, it can be predicted that it will bring many great changes in the development of the city. The major challenge faced by the unitary plan is that it must enable the growth of housing and transport facilities to create opportunities generated by this huge investment. It will promote the investment inflow in city and the extent of people and businesses being benefitted from it. In order to make the plan more successful the cooperation between private and public sector is required. Broad agreement is made on the basic transport project so that to ensure accelerated economic growth of Aukland. These agreements include the building of an additional Harbour crossing and the improvement of Northern Busway.
