A traffic management crew says it was threatened with a gun while setting up at a site.
Earlier this week the police commissioner questioned if it had happened.
But Liam Harvey, a Napier traffic management supervisor, says his crew were at Pakowhai Roundabout when weapons, including a shotgun, were pointed at them out of a car window.
He says they were massively shaken and the incident was deeply distressing.
Harvey says the police were alerted and took statements.
He says traffic management crews do face abuse, but it's from a small minority of people who are frustrated at not being allowed to get through.
Harvey says many people also approach crews at road closures to ask where they can go to help people most affected by the floods.
