Javarney Wayne Drummond, 15; Niko William Hill, 15; Jack "Jacko" Wallace, 16; Joseff "Joey" McCarthy, 16; and Andrew Goodger, 15, were all killed when the Nissan Bluebird they were travelling in smashed into a concrete power pole on August 6 last year.
Only the driver, 19-year-old Tyreese Fleming, who was on a restricted licence, survived the smash.
Outside court, Javarney's father Stephen Drummond said he was disappointed at the end sentence of two-and-a-half years.
"You choose to drink and drive and everything else ... it wasn't a pure accident."
Fleming's offer of emotional harm money was turned down by the families, Drummond said.
"It was a kick in the nuts, really," he said.
He also questioned Fleming's claims of remorse.
"He hasn't shown a lot of remorse and all the families have noticed that."
Goodger's father Richard Goodger also spoke outside the courthouse, saying he felt sorry for Fleming's family.
Since the crash, he has met with Fleming and although at first he wanted to "rip his head off", he said, he has now partially forgiven him.
"It's taken a long time for me to actually forgive him properly ... I haven't forgiven him 100 per cent," Goodger said.
"He's only a young lad. We've all done these mistakes – I've done it when I was younger. And I don't wish his family to go through what I've been through.
"It's not a father's job to bury their kids – it's their kids' job to bury them."
"You may think you've got the s****y side of things, but believe me, you don't."
Through his defence counsel Thomas Nation, Fleming told the courtroom today, in particular the victims' families, that he will "forever be truly sorry" for the harm he has caused.
He remains angry and ashamed, and regrets "all the bad decisions" he made that night, as well as the pain caused to the families.
Nation said Fleming's remorse has been apparent from the outset, highlighting his social media post the day after the fatal crash.
An offer of $20,000 in emotional harm reparation, paid at the rate of $200 per week, shows his commitment to put things right, the lawyer said.
During the impact statements, Javarney's father Stephen Drummond said his "life sucks" and a huge part of his family's lives was missing "because of stupidity and a drunk driver".
"I'm going to live a life sentence ... because I have lost a son."
Hill's last words to his mother Carissa Hill was that he loved her.
When she was told her eldest son - "my greatest achievement" had died, her "heart shattered into a million pieces, barely hanging on".
"This pain I feel is like no other pain," she told the court. "A physical pain like bricks piled on top of your chest, one after the other.
"I miss him with every ounce of me."
While accepting it was an accident, Hill said it was an avoidable accident and told Fleming in the dock that he was the reason she was left to suffer a "life sentence".
Fleming was taken to Timaru Hospital with moderate injuries after the crash and posted a message on social media the next day to let people know he was alive.
He was discharged from hospital a week later.
Fleming was initially charged with five counts of manslaughter and made a brief appearance at Timaru District Court on December 8 last year.
In April he entered guilty pleas through his lawyer Thomas Nation to reduced charges of dangerous driving causing death.
Crown prosecutor Andrew McRae highlighted Fleming's inexperience as a driver - a 19-year-old breaching the terms of his restricted driver's licence by carrying passengers – his consumption of alcohol, speed, and overloading of his car which "affected the dynamics of the vehicle".
"This was a combination of very poor decisions on behalf of the defendant that led to the tragedy that was beyond all imagination for these five victims, extended families, friends and associates," McRae said.
The Crown's starting point of between 5-6 years' imprisonment was "appropriate in the circumstances", the prosecutor said, given Fleming's "extremely high level of culpability".
Although he was under the adult drink-driving limit, he was still well over the amount he was allowed, and amounted to a "significant aggravating feature", McRae said.
Fleming had engaged in three restorative justice conferences which reports found to be generally positive, the court heard.
A final sentence of 12 months' home detention, with the maximum of 400 hours of community work, would achieve the principles of sentencing, Nation said.
"No sentence imposed by the court will ever make up for the loss of life that has occurred," he said, adding that Fleming has to live with the consequences of his actions of the rest of his life.
Fleming got his restricted driver's licence on August 4 last year, the court heard today.
About 6.20pm on August 6, Fleming got two boxes of an alcoholic vodka-based drink and drove to the local skate park at Caroline Bay.
Goodger and Hill were with him and shortly after were joined at the park by Drummond, Wallace and McCarthy.
Between 6.40pm and 6.58pm, they spent time drinking with Fleming who posted on Snapchat a video of him "vortexing" at least two bottles, sculling the contents.
Between 6.58pm and 7.02pm, Fleming got in and out of his car several times, with the boot being opened and closed.
At 7.02pm, everyone got in the car except Goodger who was standing at its rear.
Fleming got out, the court heard, opened the boot and Goodger got in.
They drove off, with Fleming in breach of his restricted licence.
While in the boot, Goodger phoned a friend and during the call a voice could be heard telling Fleming to speed up.
At the intersection at Seadown Rd, Fleming failed to approach with caution, nor did he have any intent to stop, McRae said.
He failed to slow down and took the corner at between 110km/h and 115km/h.
Fleming lost control and veered onto the grass verge.
The overloading of the car, and with the weight imbalance of a passenger in the boot, impacted on his ability to control the car and he hit a large concrete power pole at between 107km/h and 115km/h.
On impact, the car split in two and Wallace and Hill were thrown from the car.
All of the passengers were killed instantly, the court heard.
Fleming was transported to hospital and a blood sample was taken one hour and 43 minutes after the crash.
The sample returned a result of 50±2 milligrams of alcohol per 100 millilitres of blood.
The following day the defendant posted on social media from the Timaru Hospital: "Hello everyone just wanted to say I'm not dead I am very, very lucky to still be alive and I can't believe what has happened and I am so, so, so sorry to the families I have put in pain coz of stupid mistakes that I have made that has costed 5 lives."
The crash, which was one of the worst seen on South Island roads in decades, devastated the Timaru community.
