Two sisters were taken to Whakatane Hospital with moderate injuries and released four days after the crash, while the mother was taken to Waikato Hospital with arm injuries and returned home on Sunday.
However, 8-year-old Asia Floyd remains in Starship Hospital and faces a long and hard battle to return to the bubbly, sports-mad youngster she was before the crash.
Older sister Zar Floyd, who was not involved in the accident, returned home from Australia on June 6 to help out at home.
"Asia loves sports and was involved in gymnastics, netball, swimming club, ripper rugby and multisport before the accident," she said.
"She also loves running, including athletics, cross-country, road and mountain running.
"Asia is also very dedicated with her schoolwork and always strives to be the best she can be."
Asia's injuries include a severe laceration on her left leg from her knee to her ankle. She has a shattered right ankle, fractures to her left arm, and both her shoulders and left collarbone are broken.
The worst is a severe head injury.
"She has had the front bone flap of her skull removed to take pressure off her brain and has multiple skull fractures as well. Throughout her treatment so far, she has been sedated to allow her brain to rest and recover."
Doctors have told the family Asia could be sedated for up to three months and then will undergo intensive rehabilitation for at least a year.
"Right now, we're taking it in turns to be with Asia in Auckland. There's not a night one of us isn't there with her," Ms Floyd said.
"She's showing signs of movement but doctors don't want her brain over-stimulated, so they're keeping her sedated."
At the family's Otakiri home, thoughts of Asia are never far.
"We know she's a fighter and, together, we'll get through anything."
With a substantial amount of coaxing from friends, the humble Floyd family has agreed to a Givealittle page being set up for Asia's rehabilitation and to help with transport costs to and from Auckland.
