Gurjit Singh, 27, was found lying amid shards of glass outside his Hillary St home on Monday morning and police have been working to determine whether his death was suspicious.
In an update yesterday, Detective Senior Sergeant Kallum Croudis said Dunedin-based investigators and ESR scientists from Christchurch were continuing to examine the scene.
"A significant effort is being put into establishing the circumstances that led to this unexplained death," he said.
A postmortem examination was scheduled for today in Christchurch.
It emerged yesterday Mr Singh was excitedly sharing plans to holiday with his new wife the night before he was found dead.
Friends shocked at Mr Singh’s death told the Otago Daily Times there were no signs anything was wrong when they were with him the previous night.
He shared with them his excitement about his wife, whom he married in India in June, moving to New Zealand next month to live at his Hillary St house.
"He was excited for his wife to come and wanted to show her around, taking her to places like Queenstown," one said.
He arrived at their flat about 9pm and left between 10.30pm and 11pm and shared pizza and soft drink.
The friends, who used to flat with Mr Singh, were speaking with Mr Singh’s family and helping arrange for the body to be repatriated to India when the post-mortem was complete.
They said Mr Singh’s wife was distraught when she was told her husband was dead.
"As soon as she found out she screamed and actually they all started screaming.
"They really want to know what’s happened and until then they will feel unsettled."
Otago Punjabi Foundation Trust member Narindervir Singh said yesterday Gurjit Singh’s father was on his way to Dunedin but that his wife would remain in India.
Senior Sergeant Anthony Bond, of Dunedin, said police and emergency services made no attempt to resuscitate Mr Singh when they arrived at the scene after the death was reported about 9am.
"It’s obvious he’s been dead for a while."
