Tauili'ili, who was aged in his early 20s and worked as a civil engineer in Samoa, had been in a coma or several days after he suffered severe injuries in what relatives alleged was a group beating.
The father of a toddler son, he had spent several years studying in New Zealand after winning a scholarship.
"While Malaki was in a coma, his son ran up to him and kept saying to him: 'Daddy, wake up! Come play'. Today when they were doing flowers...his son was saying, 'Oh, flowers', not knowing they were flowers for his dad's funeral.''
Police Superintendent Soloi Iosefo told the Samoa Observer this week the incident occurred at the popular The Edge Marina View bar and restaurant, known to locals as Marina, overlooking Apia Harbour.
His family started a series of campaigns on social media following the incident, including spreading the hashtag: #JusticeForMalaki.
A relative told the Herald this week at least two of the alleged attackers had links to New Zealand.
A New Zealand police spokeswoman said they couldn't comment on specific cases, but confirmed they considered all requests for assistance received from overseas authorities - in line with established protocols.
