Two workers on Northland pylon site not properly trained

An investigation into the collapse of a pylon, that led to widespread power outages in Northland, has found that two workers on site hadn't been trained for the work they were doing. One of Transpower's largest service providers, Omexom, was carrying out routine maintenance, when the tower fell. The report found that the pylon toppled after nuts were removed from three of its four legs, Lucy Xia reports.
