Police have not yet released his name.
Investigator Warren Bunn, of the police Serious Crash Unit, said the deceased was not wearing a seat belt.
''We understand that young people want to be out there with their mates cruising around, but sometimes, tragically, it has serious consequences.''
He urged Northlanders to buckle up at all times.
The investigation of another crash near Kaitāia earlier the same day is also continuing.
In that case, a 63-year-old woman died after her car went into a ditch on Kaitaia-Awaroa Rd, 5km west of Kaitāia, about 11.30am.
The cause may have been a medical event but the initial post-mortem was inconclusive.
In the meantime, her death will be added to the Northland road toll, which stands at eight for the year to date.
The previous weekend a mother and her 11-year-old son died in a head-on crash near Kāeo. Three others, two of them children, were critically injured.
Driver fatigue is thought to be the main factor in that crash.
