Sophie had crossed to the middle of the road and a man had stopped to let her cross the rest of the way. She was hit by the white car in the next lane.
"It just went boom and knocked me over. I fell over and damaged the whole right side of my body. I've got bruises and grazes everywhere and a sore neck. I had a fat lip, it's split in the inside and gone black."
Two men stopped to help Sophie. Her mother Erin Nicholson said one of the men saw the driver circle around the Chadwick Rd and Cameron Rd roundabout, then drive off. The car had rectangular signwriting on the bonnet.
"She must have been thinking about stopping, then she just left."
Luckily, Sophie had just been talking to her grandparents, who were in traffic and saw the incident.
Her grandparents put her bike in their car and drove her the rest of the way home.
Sophie said she was still shaking after dinner, hours after she was hit. She will be going to regular physio appointments for her sore neck.
"She felt like it was her fault, wondering if she should have done something differently," Mrs Nicholson said.
That's the thing I don't get. Clearly, she isn't that badly injured but you have a legal and a moral obligation to stop and check. She's a child.
"We said it's not her fault, it doesn't matter if she was being the craziest driver on the road, if they hit you, they're legally obliged to stop."
Mrs Nicholson said she was angry and upset that the driver did not stop to check on Sophie.
"That's the thing I don't get. Clearly, she isn't that badly injured but you have a legal and a moral obligation to stop and check. She's a child."
After posting Sophie's story on Facebook, it was shared more than 600 times. Mrs Nicholson said the family was overwhelmed by the support they were getting.
Mrs Nicholson said she had been to the police, but no one had the licence plate of the woman that hit Sophie.
She said she had applied to Tauranga City Council to get access to CCTV footage of the incident.
Senior Sergeant Ian Campion said Mrs Nicholson had made a report with police on Monday evening and it had been referred to the road policing unit for further investigation.
He said CCTV footage would be looked at as part of the investigation, but he believed the only camera in operation in the area was focused at a nearby bar and may not take in the crash area.
"We will do what we can [to identify the driver]," he said.
Mr Campion asked that the person involved in the crash get in contact with him at Tauranga Police Station on 577 4300.
