One of the two sisters mowed down by a vehicle that lost control on a South Auckland street remains in hospital in a stable condition.
A Middlemore Hospital spokeswoman said the other child was discharged yesterday.
The girls, 8 and 10, suffered moderate injuries after they were hit in a residential street in Waiuku.
Counties Manukau Senior Sergeant Dave Readings said the children were walking along Hamilton Dr about 8am yesterday when a car lost control and mounted the footpath.
They were taken to hospital.
Staff at the school the girls attend were in shock after the crash.
"They are really lovely, sweet girls," said a View Road School administration worker.
"They were following the road rules.
"We're all in shock and just glad it wasn't worse.
"It's bad enough as it was but we're thankful they weren't killed."
School principal Chris Hull raced to comfort the injured sisters as soon as she heard about the crash.
"She told me one of the girls was in extreme pain," the school worker said.
The girls' grandmother was also believed to be walking with them when they were hit.
A 30-year-old Waiuku man has been charged with two counts of dangerous driving causing injury.
