The crash left so many injured, including three of Barnes’ children, four rescue helicopters were needed to airlift them all.
It was the largest emergency service response since the 2019 Whakaari White Island eruption.
Barnes, 32, was charged with refusing to provide a blood specimen - a move Judge Peter Davey said could be assumed to imply she was intoxicated - and five charges of aggravated careless driving causing injury.
Multiple victims attended her sentencing in the Whangārei District Court this week, with heartbreaking victim impact statements from Izzak and Briarley Birch.
Police prosecutor Valeria Benjamin read Izzak’s statement on his behalf. It was candid about the life he had created despite a tough childhood growing up in poverty in Ōtara.
“I often lived in halfway houses, we moved a lot ... I come from a family with a lot of alcohol and drug abuse, however, instead of using it as an excuse ... I used that as motivation.
“I had to overcome the odds to get to where I was before the accident.”
For the past 15 years he held roles, many voluntary, across Northland teaching youth life skills and more recently at the Whangārei District Court helping whānau navigate the family court system.
“My lifetime of hard work has been taken away from me ... however it is not just my life but the many young men out there that need support who are now down one person in a critical space.”
As a result of the crash, Izzak suffered severe internal and external injuries, including a severe brain injury, loss of most of his eyesight, had countless surgeries and had to be resuscitated twice while he was in ICU for 30 days.
“I am unsure what my future will be like and what kind of father and husband I will be,” he said.
“I feel like my life has been cut off before the age of 40 when I was just making progress in life.”

His wife Briarley was also injured and spoke of her successful career working with children in the care of Oranga Tamariki, a job she can no longer do as she cares for her husband.
“I loved my work, I feel so sad this has now finished and I have no idea what I will do at the age of 50,” she said.
“You denied drinking or taking drugs on that day ... but you should be treated the same way as if you were found to be drinking or over the limit ,and the reason for that is because otherwise everyone could refuse to give blood and simply say they weren’t drinking,” Judge Davey said.
Judge Davey said it wasn’t a moment of inattention as the public had raised concerns about the way she was driving.
“Your actions were deliberate and in my view you showed a complete disregard for others, including your own children.”
Barnes was sentenced to eight months home detention and disqualified from driving for 18 months. She did not offer an apology in court.
