Pedestrians watched in horror as a runaway double-decker bus rolled down a hill and injured three people in downtown Auckland.
A witness said a young woman with a child was struck by the City Sightseeing Tours bus.
"She went under the bus and the rest of us managed to get out of the way," she said.
"Everyone jumped in and helped her out from under the bus. Then we had to locate the baby."
"It was absolutely terrifying".
Police have confirmed three people were injured by the runaway bus.
A second witness told the Herald he saw a double decker sightseeing bus rolling down Victoria St and a person, presumed to be its driver, running after it.
He heard people screaming after the bus crashed into a construction site on the corner of Victoria and Albert Sts.
The witness said he heard crunching as the bus crashed backward through a construction barrier.
The witness did not notice whether there were people were standing in the construction area but the bus had gone through an area where pedestrians crossed the road at the traffic lights - and it was busy as it was lunchtime.
Despite the steep hill the bus came to a stop when it hit the construction site.
The bus had started rolling slowly, so he assumed it was being reversed - until it sped up and he saw the driver running after it.
A reporter at the scene said a woman appeared to have been trapped but was freed now.
She was sitting down holding a young child and was being attended to by fire officers. She appeared to have escaped serious injury.
Two ambulances have arrived at the scene and there are two fire trucks and two police cars.
There was a large crowd of people milling around but police were moving them on.
The area was being cordoned off.
The bus was inside the concrete barrier on the side of the road. It had clearly scraped against the barrier and rolled back into the roadworks fencing. It had also pushed over a big green tin barrel with a mobile traffic light in it, which likely was filled with sand or concrete.
There was also an abandoned pram which did not appear to be damaged and appeared to belong the woman.
A WorkSafe spokeswoman said they had been notified.
"We are making initial inquiries to establish what has occurred, and what our next steps might be."
