- Summary
- The purpose of this report is to provide an overview of natural hazards in the Hauraki
district as a basis for guiding and prioritising work activities by Hauraki District Council
(HDC) and Environment Waikato (EW) for 2006/07 and beyond. This report also
provides a useful insight into the district’s natural hazards as part of the scheduled
review of the Hauraki District Plan.
Both agencies have responsibilities for the management of natural hazards in
accordance to a complex set of statutory responsibilities, but primarily via the Resource
Management Act 1991.
Known natural hazards in the Hauraki district are identified and explained. Hazard
scenarios are defined for each natural hazard and existing risk management controls
are outlined. A preliminary (qualitative) risk analysis is then undertaken, and an
evaluation of the risk from each natural hazard is made as a basis for prioritising risks.
This approach is very similar to the hazard assessment that was carried out for the
Thames Coromandel district as part of the Thames Coast Flood Risk Mitigation project.
River flooding hazards pose the greatest risk in terms of potential loss of human life,
social disruption, economic cost and infrastructure damage. Coastal flooding has the
second highest risk, and earthquakes have the third highest risk. The report also
identifies various factors/considerations that are likely to affect natural hazard planning
such as climate change, sea level rise, and tectonic deformation.
