Yesterday's crash has left the tight-knit Te Araroa community of about 200 people where "everybody knows each other" in shock at what is being described as an "unimaginable" tragedy.
Emergency services responded to yesterday's crash, near Te Araroa, about 5.45am.
Te Araroa and Tikitiki firefighters responded, along with police. St John Ambulance from Ruatoria was also called out. St John officers pronounced the victims dead at the scene.
