A review into how the public and local politicians were kept in the dark about a herbicide scare that closed two Hunua Ranges dams feeding Auckland's water supply has begun.
Auckland Council chief executive Stephen Town yesterday backed the actions of Watercare Services to ensure public safety was never at risk after traces of the herbicide metsulfuron-methyl were detected in the dams' water.
"I am confident that proper safety procedures were in place and were followed by the parties concerned," he said.
But Mr Town acknowledged concerns that the public and councillors were not informed about the incident, saying he would undertake a review of the council's reporting procedures by the end of the year.
