Others who knew Ali described him as "a wonderful young man" and an "amazing" person.
"Such a beautiful soul! Will miss his 'Colgate smile'," said one woman.
Police were initially called to the scene after reports of a serious assault and a hammer-wielding man seen "saturated" in blood.

Ali's body was found soon after and a homicide investigation is now underway.
A 38-year-old man has been charged with murder and appeared in the Christchurch District Court earlier this week.
Ali was a manager at Indian grocery store Krazy Price Mart.
