Transpower says contractor Omexom is working through its own recommendations after the June pylon topple that caused a power outage in Northland.  

An Electricity Authority report found bad practice that caused the Transpower tower to topple had probably happened before.  

Unsupervised, inexperienced maintenance crews from contractor Omexom unfastened three legs at once.  

Transpower Executive General Manager Mark Ryall told Mike Hosking you do need to be able to train people on the job, otherwise they'll never become competent.  

But he says a trainee needs to be under direct supervision, and in this case they weren't adequately supervised.
