This article draws on quantitative survey evidence to explore the role of dynamic capabilities in a post-disaster environment, that of Christchurch in New Zealand after the 2010 and 2011 series of major earthquakes. We develop a model to examine the relationship between dynamic capabilities, disaster-related changes to the firm’s resource base and its performance. The hypotheses are tested using a sample of 545 small firms that have been affected by the earthquakes. Results highlight the importance of a firm’s proactive posture and capability to integrate resources in recognising new opportunities in an environment characterised by high volatility and increased uncertainty. These findings offer important theoretical and practical implications.
