RiVAS is designed to provide an explicit and standardised method to develop assessment criteria and significance thresholds for multiple in and out of river values. The method can be applied to national and regional planning under the Resource Management Act as well as being used for other purposes such as advocacy activities.
The RiVAS tool (and its underlying method) uses a multi-criteria analysis (MCA) approach and aims to:
The intention was to define a method that has applicability for all river values. The method, while operating under a standard framework has the capacity to facilitate variation in its implementation to accommodate the particular characteristics of each river value.
However, once applied for a specific river value (e.g., whitewater kayaking), the expectation is that the method developed for that river value will become the standard approach to significance assessment for New Zealand rivers with respect to that value. The eight river values tested as part of method development should now be considered to have a reasonably standard approach for assessment.
The method is intended to provide a means to inform decision-makers as to the significance of particular values, using a consistent approach. It does not (without further development and evaluation) extend to the exercise of prioritising between different river values.
