Winter pleaded guilty to careless driving in August. In court, Judge Paul Kellar said Winter seemed "remorseful" of his actions.
The sentencing began with two pastors who said prayers in Samoan and English, followed by 10 victim impact reports.
Daly's wife, Sefulu Annie Teevale-Daly, suffered skull bruising and a lumbar spine fracture, while Zion Benet Taliauli and Zachariah David Fuata'i, both age four, had traumatic brain injuries and were taken to Auckland's Starship Hospital in critical condition.
Ms Daly recalled what happened before and after the crash that killed her husband and nephew.
"From the very moment I realised the truck was not going to stop, the truck's fluorescent headlights shining into my eyes, the impact of the truck ploughing into our vehicle to the moment I regained a slight bit of conciousness, I placed my hand on my dear husband's hand [only] for it to be frozen cold in an instant."
She spoke of her grief over losing her husband who was her best friend, and wept as she talked about their four-year-old son questioning where his Dad had gone.
Ezekiel's father, known as Junior, fought back tears as he told the court that his son's dream of becoming a famous rugby player could now never happen.
He told Winter he wished he could have died in the accident, in place of his son.
Zachariah's father David Fuata'i told the court he quit his job to care for his injured son. He said the crash left him strained emotionally, financially and even threatened his marriage.
His wife also gave a tearful statement and said to Winter, "I forgive you because He [God] first forgave me."
In Winter's statement to the court, he said he was truly sorry for the pain and suffering he caused as a result of a moment of inattention.
Judge Paul Kellar told the victim's family no sentence could ever soothe their grief, and he hoped people would learn from the seriousness of this tragedy and drove carefully and safely through traffic lights.
He said Winter was a professional driver of a large fully laden truck, and the level of carelessness was moderate to high, but the truck's GPS said he was not speeding.
Outside court, the victim's family said although they hoped for a hasher penalty, it gave them some closure they desperately needed.
