"Our national groundwater resources are valued at $8 billion but few of us know anything about the relationship between our 200 aquifers and our streams, rivers and bores.
"We know even less about the wide range of organisations that regulate, deliver and monitor our water supply. While this is reportedly New Zealand's worst water contamination crisis, it's by no means the first. Queenstown, Auckland, Ashburton, Waikato and Te Aute College have all had outbreaks since 1993 and Ministry for the Environment figures estimate 18,000 cases of waterborne illness every year.
"What's happened in Havelock North could happen elsewhere so, voters need to choose people capable of exercising good governance over water.
"Last year a Wellington Water report showed that fewer than 75 per cent of freshwater sites in Wellington city met water quality standards.
"This shouldn't be a blame game. Staff and elected representatives on district and regional councils need to work together to make sure systems are compliant and scientifically robust. Assets of the council controlled organisation,Wellington Water Company, are valued at $550 million, so elected representatives need to do their homework and get their heads around the science, engineering, economics and management of water systems."
