These maps have been created from analysis of information using modern techniques and based on the best information currently available. However, they do not necessarily show the greatest extent of river flooding experienced in the past, or likely to be suffered in the future.The river flood hazard maps indicate the extent of land that has been assessed as likely or potentially at risk of flooding by the rivers, under the different rainfall / storm scenarios including climate change.The maps cover all our river catchments and associated rivers in the region.While the maps have been quality controlled, their accuracy cannot be guaranteed. Accordingly, these maps should not be relied upon as the sole basis for the making of any decision in relation to potential river flood hazard risk. Further, themaps should be interpreted only by an expert duly qualified to interpret these maps and when so interpreted, should not be utilised without reference to other source information and data.Northland Regional Council makes no representations, warranties or undertakings about any of the information in these maps and/or electronic files including, without limitation, their accuracy, their completeness or their quality or fitness for any particular purpose.
