A Northland man who allegedly waved a rifle in the air after a crash early this morning is in police custody awaiting a mental health assessment.
The two-car smash happened on Oromahoe Rd, just off State Highway 10 south of Kerikeri, sometime after 6am.
Senior Sergeant Peter Robinson, of Mid North police, said a 41-year-old man got out of one of the vehicles after the crash and presented an air rifle.
He did not point it at the people in the other vehicle but was ''waving it around and ranting and raving''.
It was not immediately clear what kind of firearm was involved so police responded in numbers.
