Additionally, facilities that people take for granted in larger population centres, such as supermarkets and schools, are more widely distributed in low population density regions. We adopt the 14 November 2016 (Kaikōura) earthquake in New Zealand as a case study to explore critical infrastructure challenges and impacts, service disruptions, and community adaptations in four small North Canterbury and Marlborough towns – Waiau, Culverden, Seddon and Ward. However, behavioural, infrastructure and legislative adaptations can be inherent or quick to evolve in small towns with frequent service disruptions. Despite these factors, small towns are often underrepresented in impact assessments and appear to have been a low priority for investigation in the past.
