One of Nelson City Council’s responsibilities is to manage risk from natural hazards. Council is required to investigate natural hazards, and to make available the relevant research.
Council fulfils this function in various ways, including:
Council has commissioned various technical studies to better understand areas that may be susceptible to natural hazards. This includes assessments of fault hazard, liquefaction, slope instability, river flooding and coastal inundation. Further information on each of these natural hazards, and mapping of natural hazards, can be accessed through the links provided above.
Our understanding of natural hazards in Nelson continues to evolve as new areas are assessed and we undertake more detailed studies in areas known to be susceptible to natural hazards. Methodologies for undertaking assessments also change over time. Therefore, the information provided on these webpages may change as we receive new and updated information.
Information regarding tsunami, including Tsunami Evacuation Maps and frequently asked questions, is held on the Nelson Tasman Civil Defence Emergency Management (CDEM) website.
Property owners will be keen to understand the impact on the availability of insurance and their premium levels in the future if natural hazard risk information is changed on their LIMs or property titles. Please read the following information for property owners from the Insurance Council of New Zealand.
Nelson, like much of New Zealand, is susceptible to a range of natural hazards. Natural hazards that may affect the Nelson region include earthquakes (causing fault rupture, shaking and liquefaction), river flood and coastal inundation, slope instability and coastal erosion. Natural hazards pose a risk when they affect people, property, and the environment.
