Hamilton bus drivers today set up blockades and are reportedly stepping in front of moving buses as strike action heats up.
The First Union members set up a blockade at Hamilton's Transport Centre as well as the Go Bus depot.
However, Waikato Regional Council's public transport operations manager Andrew Wilson said there had even been reports of union members stepping in front of moving buses.
Wilson said buses that were unobstructed and able to continue operating safely would do so but the action meant there were limited services running again today.
"We respect people's right to a peaceful and respectful protest. But union representatives putting themselves or others in danger is a serious concern for us.
