On this webpage, you will find simplified versions of the financial models WICS used in its analysis of the potential economic benefits of three waters reform. These models demonstrate the approach WICS took to calculate average household costs for each council and amalgamated entity, including how these have been informed by the information councils provided through the Request for Information process.

In addition to these models, there are accompanying slide packs for each council and amalgamated entity that set out the results of analysis to test the sensitivity of the modelling to key assumptions, including assumptions around levels of efficiency and future investment need. As the sensitivity analysis on a stand-alone council basis was completed prior to cabinet decisions on the preferred number and boundaries of entities, the slide packs for councils on a stand-alone basis report on an illustrative amalgamation scenario (either scenario 2 or 3 in the WICS analysis) which is slightly different to the Government’s preferred scenario (scenario 30). The models, slide packs and sensitivity analysis for the amalgamated entities have been prepared on the basis of the Government’s preferred scenario.
