Hon NANAIA MAHUTA (Minister of Local Government): Fa'afetai tele lava. I've seen reports released by the Department of Internal Affairs yesterday which provide New Zealanders with a clear picture of the urgent problems our water services and infrastructure face. The reports include analysis of the economic benefits of reform by the Water Industry Commission for Scotland (WICS), independent reviews of WICS' methodology by Farrierswier and Beca, and an analysis of the effects of the proposed reform on the economy and affected industries by Deloitte. Together, the reports confirm the need for major reform to upgrade and maintain our water infrastructure, protect our environment, and avoid unaffordable increases to household bills. They identify investment of between $120 billion and $185 billion needed over 30 years, to ensure New Zealanders' drinking-, waste-, and stormwater infrastructure meets acceptable public health and environmental standards. The reports also highlight the economic benefits we can unlock by tackling these challenges, such as job creation and an increase in GDP and tax revenue.
