A 17 year-old Kapiti man is in a critical condition after being attacked outside a shopping centre in Paraparaumu.
The man is now in Wellington Hospital on life support, after being found unconscious by police in the early hours of this morning.
Detective Inspector Mike Johnson said police located the man near the back of KFC in the Coastlands carpark.
He was taken by ambulance to Wellington Hospital where he has since undergone surgery.
"An investigation is now underway to establish the circumstances which have led to this man being found unconscious. It's too early to speculate on what has occurred or whether any weapons have been involved."
Johnson said early enquiries by police so far established the victim was outside the Retro Bar at Kapiti Lights before 3am, where it appeared he got into an altercation with a group of people.
"From there, the male has then gone through an alleyway which leads to Coastlands. We have cordoned off this area to complete a scene examination.
"The area where the male was located is also cordoned off, whilst a scene examination is completed," Johnson said.
Police would like to hear from anyone who was at the Retro Bar in the early hours of this morning and witnessed an alleged altercation in the carpark area outside the bar.
The victim is a male Maori, who was wearing a blue and beige checked shirt with a white t-shirt underneath, blue jeans and light brown boots and a black woollen hat.
