The Crown says Smith’s actions were part of a “spree” of offending during which Smith violently attacked two other men - also fleeing in their vehicles.
But Smith says he was acting in “self-defence” when he injured Hawkins.
A man working in the site office - a portacom - heard the door of his ute open and close just outside.
He looked outside and saw Smith standing beside the vehicle.
Smith said he’d seen the door open and simply closed it.
The man thought nothing of it and went back inside. Ten minutes later, Smith walked in.
Mallett said the pair engaged in “a brief period of small talk” and the man showed Smith the site plans.
“Without any warning or provocation, he put the victim into a chokehold from behind … [He] had one arm around his neck, using his second arm to pull the first tighter,” he said.
Smith’s force lifted the victim from his seat and both fell to the ground.
He continued to choke the victim, whose eyesight went “blurry”, and then started to punch him with one arm as he tried to “increase the grip around his neck” with the other.
The victim managed to free one hand and gouged at Smith’s eye. Smith “relinquished” and got to his feet, picking up a 23cm piece of wood that had splintered from a chair during the tousle.
He “began advancing” on the victim, demanding to know: “Where is your sh**?”
Smith then took the victim’s phone and fled in his ute after locking him in the portacom.
The victim managed to escape through a window and flagged down another worker for help.
He was lying on his bed in a pool of blood with his throat cut.
He was “making gurgling noises” and was still warm.
But when paramedics arrived soon afterwards, Hawkins was declared dead.
Mallett said Hawkins “suffered significant blunt force trauma to his head” - a force so strong it broke both eye sockets and damaged his brain.
He had a 12cm-long, 4cm-deep cut on the front of his throat and had received a 5 to 7cm-deep stab wound to his neck that had pierced both his jugular and oesophagus.
“The Crown case - supported by findings of pathologist - is that the knife wounds to neck and throat occurred after Mr Hawkins had been rendered unconscious and incapacitated by the blunt force wounds to his head,” said Mallett.
“Mr Hawkins had no blood on his hands ... at no point was he conscious and able to try to staunch the bleeding. Put simply, Mr Hawkins was beaten to unconsciousness, and while incapacitated - and with no way to defend himself - he had his throat cut.”
Mallett said Hawkins’ head injury was “severe enough to have caused his death in their own right”.
The knife wounds could have been survivable if he had been able to seek help.
His cause of death was a combination of head injury and blood loss.
After allegedly murdering Hawkins, Smith fled in his car - but not before he left a bloody palm print on a wardrobe door.
The fourth incident: Library attack
Smith drove Hawkins’ car - erratically and dangerously - to Halswell.
Just after 4pm, Smith stopped at Prebbleton and purchased a mince-and-cheese pie.
Police were searching for him in relation to the stolen car he was driving - but Mallett said at that stage, the “spree” of offending “was not attributable to the same person”.
At 6.10pm, officers spotted the car and pulled Smith over.
He tried to pass himself off as his brother, but officers found his licence in the car and arrested him again.
Mallett said the lie was “a clumsy attempt to avoid responsibility”.
The police interview
Smith was interviewed by police and the jury will be played the five hours of footage later in the trial.
Mallett explained that for the “majority” of the interview, Smith “avoided questions put to him ... claiming instead to be hearing voices and expressing concerns that ‘the gangs were out to get him’.
“At the end of interview, he made important admissions. He admitted going inside Daniel Hawkins’ unit. He said the door was open and, despite not knowing who he was, went in and took the keys.
“He claimed Mr Hawkins was smoking meth and that ‘he raged out at me’ ... he further claimed Mr Hawkins grabbed a knife and tried to stab him.
“He said he felt scared and ‘chose to stay alive’. He admitted attacking him by choking him, but he did not admit cutting his throat.”
The defence: Self-defence and reasonable force
Defence lawyer Abbie Hollingworth also gave a brief opening statement on behalf of Smith.
She said it was crucial for the jury to keep an open mind and not make any decision until they had heard all the evidence.
“But is it not. You must not jump to any conclusions yet,” she said.
“The most important issue for me to flag is that one of self-defence ... Mr Smith accepts he got into [an] altercation with Mr Hawkins, assaulted him, and he later died.
“However, you will hear that Motu Smith told police [Hawkins] used force ... that he thought he was going to be killed so he defended himself.”
Hollingworth explained briefly that under New Zealand law, reasonable force is allowed when a person legitimately believes their life or safety is in danger.
The jury will hear more on that when the defence calls evidence.
The trial is set down for three weeks, and during that time the jury will hear from a number of witnesses, including people who lived at the housing complex, forensic experts and police officers who worked on the investigation.
Coleman was missing Hawkins terribly, then got a phone call from police to say he had died.
“I woke up to police telling me [he was dead],” she said.
“It was heartbreaking. I haven’t slept since, I don’t think I am making any sense … My daughter and I went to his house today and left flowers and a love-heart sign with words.
“He was such a cuddly bear, taken away too soon. No matter what - nobody deserves to be taken this way.”
Coleman acknowledged her partner’s dark past, his previous convictions, his violence and his gang connections.
“He had such a caring side … we both had issues, and he was on current charges for assaulting me, but it would never take away the love I have for him,” she said.
“Nothing will ever replace him or the happiness he brought - that smile of his was not [seen often], but it was beautiful.
“His beautiful, handsome smile … his affection, his arms wrapped around me. He knew how to comfort me at the right times.”
