Mrs Twiname bounced off the bonnet, over the top of the car - which was travelling at about 20km/h - and landed on the road behind it.
"I was terribly lucky I didn't break any bones, very lucky I wasn't killed," she said.
Not long after she was discharged from Auckland City Hospital she was contacted by AA Insurance.
"They told me about the damage to the car and how much it was going to be, and that I was liable and had to pay it. I couldn't believe it.
"My husband has cancer and I'm looking after him at home, my life isn't easy. This was the last thing I needed - I didn't need any more stress in my life."
Mrs Twiname was told her house and contents insurance should cover the damages. But, when she and her husband moved into a retirement village they cancelled their policy.
"The chances of fire or burglary are zilch so we cancelled all of that."
She sought legal advice and had lawyer Vernon Tava contact AA on her behalf.
"Her savings would be totally wiped out by this claim," he said. "I have spoken to the insurers on two occasions and explained her circumstances. They insist that she is liable."
But yesterday, after Herald inquiries, AA Insurance conceded there was no case against Mrs Twiname.
"We absolutely do not, now I've found out about this, intend to pursue Mrs Twiname," said head of customer relations Suzanne Wolton.
"That claim should have been flagged or raised by one of our recovery consultants. It's certainly not a case we would normally pursue.
"We're obviously sorry for causing Mrs Twiname the stress she has been caused and we will contact her immediately to resolve the situation and apologise.
"We are also going to review our internal processes to make sure a similar situation doesn't arise in the future. It shouldn't have happened."
When told about AA's turnaround Mrs Twiname was overjoyed.
"It's absolutely wonderful, it really is a relief," she said. "I can't tell you how much this means."
