The increased occurrence of natural disasters over the years have led to greater awareness of their impacts and the need to be prepared. New Zealand has encountered tsunamis, earthquakes and recent floods. Because of its geographical location, New Zealand is vulnerable to environmental risks . Disaster preparedness has become a focus in New Zealand and within disaster preparedness is post-disaster reconstruction planning. This paper evaluates the availability of resources for post -disaster reconstruction of the Wellington State Highway, with a focus on aggregates, cement and concrete. A benchmark of the resources required for reinstatement of the state highways was established using a re source estimation method. The results indicated that post-disaster reconstruction of the Wellington state highway is likely to be constrained by the limitations on construction resources in New Zealand such as aggregates, cement and concrete. This paper shows what alternative arrangements can be made given any shortages of these resources in a post-disaster environment.
