Affordable housing is a challenging problem which needs to be solved through both government and industry initiatives. Improving construction supply chain has the potential to expedite the supply and achieve affordable housing. However, there is need to develop linkages between affordable housing problem and construction supply chain problems. A problem taxonomy approach has been used to develop problem clusters (as housing, affordable housing and construction supply chain) through detailed literature review of studies and reports related to New Zealand. A problem taxonomy is proposed which showed generic, main and specific configuration problems of construction supply chain in New Zealand. This taxonomy helps to develop relationships, research hypothesis, questions and ontologies to investigate affordable housing problem, and drive solutions through configuration of construction supply chain. 

To begin, there is an interesting global phenomenon today in population demographics. The world population is aging. Recent demographic figures have for some time showed an increasing trend toward an aging population in both Eastern and Western societies (Kim et al. 2000: 5).
