Police are reviewing security camera footage as they investigate the puzzling death of a security guard on his first day on the job.
Waitakere CIB investigators are continuing their inquiries into the "unexplained" death of Charanpreet Dhaliwal, who was found dead at a west Auckland construction site on Friday.
The 22-year-old was reportedly found slumped over a concrete slab at a Fulton Hogan construction site, near the Lincoln Rd North Western Motorway overbridge in Henderson.
The man was reportedly working his first shift for CNE, a security company subcontracted by Fulton Hogan.
Waitakere District Field Crime Manager Detective Inspector Greg Cramer said the circumstances around the victim's death were still unclear, and police were keeping an open mind.
