Elledy has had to attend around 100 appointments at Middlemore's burns unit for specialist skin treatment to heal her scars, and is still required to go once every three months.
"She has been through quite a lot," Harawira said. "We were lucky her hearing and vision weren't affected. We are hoping she will grow out of her scars."
She said her daughter was still traumatised by the sound of fireworks.
"She likes watching them but she doesn't like the sound and I think that is due to trauma. We took her to a Guy Fawkes show last year and we had to leave when it started. She is still affected by loud noises."
Harawira now supports a ban on the public sale of crackers and rockets.
A 30,000-signature petition calling for a ban on private sales of fireworks was rejected earlier this year by a Parliamentary Select Committee.
Harawira said the volatile nature of fireworks meant accidents still happened even in safe environments.
One the eve of the official start of public sales, she urged parents to keep a close eye on those setting off rockets, saying she hoped other families didn't have to endure what hers had been through.
"It was just a $50 little packet of fireworks from the side of the road that caused so much trauma," she said. "I couldn't imagine anything worse for a parent to be doing over Guy Fawkes," she said. "Go and watch a show instead."
According to ACC, 934 people sustained Guy Fawkes-related injuries in the past two years, costing the taxpayer almost $500,000. The injuries involved burns, lacerations and soft-tissue injuries.
