Stop/go operators are a common sight on state highways over summer, at emergency or planned road maintenance sites.
They are there all day, in all weather, in their hi-viz gear, armed only with a sign, a walkie talkie and a smile.
And while it might not look like a dangerous job, Waka Kotahi NZ Transport Agency Northland system manager Jacqui Hori-Hoult says it can be.
"Just before Christmas we had two incidents where stop/go operators reported near misses, where they were nearly hit by vehicles passing too close or speeding through the work site," she said.
"This is unacceptable driving behaviour, because it puts everyone at risk, not just the stop/go operator, who is the first person motorists encounter as they approach a work site, but other crew members and road users as well.
