Hon NANAIA MAHUTA: Without reform, average household bills in 2051 are forecast to range from $1,900 to $13,900 a year. This is simply unaffordable for many communities. For example, in Auckland, it's been recently reported that water bills could double in less than a decade. Central and local government accept that the current arrangement of 67 council water providers is not working. The Government is proposing a small number of large publicly owned water service providers. Under reform proposals with three to five providers, those figures would be much less, ranging from $800 to $1,800 a year. The modelling underpinning the reports is based on data provided by every council. I'd like to acknowledge their hard work and the expertise of council staff that helped us put together this data.
