Police say the teenage couple brutally bashed in a west Auckland park on Sunday may have lain unconscious for several hours and are lucky to be alive.
The 19-year-old man and 17-year-old woman remain in a critical but stable condition in hospital today as police hunt their attackers.
The female victim has had surgery today to repair damage to some of the broken bones in her face.
Police say they still have no idea who attacked the couple or why the attack took place.
