UPDATED 10.53am: A woman is in a serious but stable condition in Auckland Hospital after being hit by a truck in Milford this morning.

Emergency services worked to free the woman pedestrian, who was hit near the intersection of Kitchener and Milford Rds about 8.35am.

The woman hit was a cyclist in her 50s.

North Shore Road Police Sergeant Cecil Ross said the woman had serious arm injuries.

He said the accident happened when the truck turned left from Kitchener Rd into Milford Rd.

The woman appeared to be cycling straight through the intersection and it was the front of the truck that hit her.

The truck is a delivery or moving vehicle with a roller door at the back.

The driver was very shaken up.

Linda Gore, the manager of Crafty Knitwits on Kitchener Rd, said she didn’t see the crash but saw the bike “buckled” on the footpath afterwards.

“A customer sitting in the window heard the crash. The truck driver was sitting in the truck in shock. Someone had to help him out of it.”

The area was mostly cleared as of 9.40am, but police were still at the scene.

A KiwiBank employee who wished not to be named was walking to work when she heard a scream.

"I turned around and saw the bike go under the truck and it was bouncing up and down under the truck.

"There was a lot of howling and screaming."

The woman ran straight to the scene and her colleagues bought a tarpaulin to cover the cyclist, who was pinned under the wheel.

"People were running up the road to help and were already on their cellphones calling an ambulance."

The other KiwiBank staff were angry to see a passing motorist taking photos of the crash from their car.

One staff member said: "That could be someone's mother, daughter or wife. How would they feel if the tables were turned?"

Across the road, Ross Jones at Milford Butcher said he too heard screaming.

"We heard a bloodcurdling scream. That was the only thing that alerted us to it.

"We rushed to the door but [the accident] had already happened."

He said there was not many accidents at the intersection.
