Emergency services were notified of the single-vehicle crash, at the intersection of Wingatui and Soper Rds, about 12:25am.
"The vehicle rolled after travelling down a closed road that was under construction, causing damage to some fencing and equipment in the area," police said.
"The occupants left the scene after being picked up by another vehicle and have not yet been located."
A resident who declined to be named said she heard a "large crashing sound" just after midnight.
"All the emergency services came to the scene; you could tell someone must have done a runner.
"Everything in the vehicle was just banged up.
"The crash was quite something."
Police said inquiries were ongoing to identify those involved.
