Enhancing community resilience : innovative strategies for flood risk management in New Zealand : a thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy in Built Environment, Massey University

Abstract

The increasing frequency of flood events, coupled with the challenges posed by a changing climate, has heightened the need for enhanced flood resilience in communities, particularly in regions like Northland, New Zealand. Despite widespread awareness, flood risks continue to impact communities, and existing flood management strategies often prioritize response and recovery over proactive, longterm risk reduction. This research investigates the gap in current flood risk management practices, focusing on community resilience, preparedness, and the implementation of sustainable, proactive flood management strategies. The study explores the importance of bottom-up governance and community-driven solutions, proposing a balanced approach that integrates risk reduction with community engagement to build resilience.

The research utilizes a mixed-methods approach, combining qualitative case studies and quantitative surveys to capture both local community experiences and institutional perspectives. Through interviews, surveys, and analysis, the study identifies the key factors influencing community resilience, such as intergenerational knowledge gaps, local knowledge integration, and effective stakeholder collaboration. Findings suggest that while flood preparedness is often discussed, it remains insufficiently implemented at the community level, particularly in flood-prone areas. Moreover, proactive measures for long-term flood risk reduction are underdeveloped, with most attention focused on immediate response and recovery efforts.

This research contributes to the understanding of how community resilience can be effectively enhanced in the context of recurring floods, offering insights into the importance of community engagement and the integration of local knowledge in flood management planning. The study provides actionable recommendations for improving flood resilience in Northland and other regions with similar flood risks, emphasising the need for collaborative governance, sustainable infrastructure, and adaptive policies that integrate long-term preparedness with risk reduction efforts.
