Police are looking into how a police car collided at "low speed" with a civilian's car in west Tāmaki Makaurau Auckland during Thursday morning's peak traffic.
A police spokesperson told Newshub officers were heading to callout about 8.35am with their lights on going south along Universal Drive in Henderson.
When they reached the intersection with Lincoln Road, the police car hit another, but nobody was injured, police said.
The vehicles were towed from the scene shortly after the crash.
