The death of a 19-year-old man after a fight at a party has triggered a public outcry and a debate over what some see as a growing streak of violence that involved drugs and alcohol among South Auckland youth .

Counties Manukau Police said an investigation was underway into an unexplained death of the teenager that occurred overnight in Calthorp Close, Favona.

He died in Middlemore hospital early this morning as a result of his injuries, Police said.

But some South Aucklanders took to Facebook and said the incident showed how violence among Mangere youth increased because of alcohol and drug abuses.

The incident concerned Tevita Ofanoa and he wished his children would not follow the obvious trend.

Police said a small party has taken place at an address in the suburb of Favona last night, where a fight has then developed.

“Police are speaking to several people in relation to this incident and the scene examination continues to take place.

“A post-mortem is expected to take place later today and until then the cause of death cannot be confirmed”.
