SIMON COURT (ACT): As a civil engineer, I'm really interested in how to solve the problem of three waters, ageing water infrastructure, and how do we connect pipes to land so that people can build houses and communities. Now, the Government has emphasised disease outbreak—E. coli in Havelock North. That was primarily a regulatory failing. It was public health agencies and a regional council that failed to protect the water source that resulted in people getting sick and, tragically, some dying. But that problem's largely solved. The Government's established Taumata Arowai, a water regulator. In fact, the chief executive, Bill Bayfield, told Mike Hosking on ZB that he had all the tools he needed in his tool box to make sure that councils delivered safe drinking water.
