Police are investigating after an injured man died shortly after arriving at Middlemore Hospital last night.
The man had critical injuries when he got to the hospital in a private vehicle just before 8.30pm.
He died shortly after arriving, a police spokeswoman said.
Counties Manukau Police have launched a homicide investigation, and are examining the vehicle he arrived in, she said.
