Bright said police were not yet in a position to release the name of the young man killed, but would do so in due course.
Authorities are appealing to the public who may have been in or around Addington Ave on the evening of New Year’s Eve (Sunday) to about 3.30am on January 1.
They are particularly interested in anyone who may have dashcam footage that could help in their investigation.
Police and emergency services were called to the scene about 3.20am.
Police said at the time two people had been found inside a car unresponsive and taken to hospital.
Officers in jump suits, masks and gloves were later seen examining a car in the middle of the street as armed police stood guard at the top of the road, where a large cordon had been placed.
One Addington Ave resident said people had been partying and letting off fireworks on the street all evening.
“We didn’t hear anything because people were letting off flares in the street,” he said.
“The first we heard of what happened was waking up and seeing the crime scene outside your door.”
