A reporter at the scene said there was a police car, ambulance and fire engine in attendance.
One lane of the highway is blocked and traffic is crawling, he said.
"There's a damaged road bike propped up on the armco of the bridge at the intersection of Te Puke Highway and Collins Ln. The road is still down to one lane for traffic heading west. Traffic heading east is diverted via Manoeka Rd," he said.
