Adlam bowed his head throughout the reading of the four victim impact reports from Te Rihira's parents and her older sister, who also read a statement from Te Rihira's grandmother.
Te Rihira was described by her sister as "a beautiful young lady with a big heart who cared deeply about people".
Justice France told Adlam he had an appalling driving record and numerous driving offences that spanned 12 years.
Adlam drove 11 times while disqualified.
Adlam had swapped a playstation for a Subaru Legacy a month before the November 10 crash, but was told to tow it because the right front brake had seized.
He attempted to fix the brake hose with a clamp and continued to drive the vehicle.
On November 10, Adlam who was a neighbour of the McGhies, had offered to drive Te Rihira to a friends and then back to school.
He drove his vehicle between Otaki and Levin on a road where the tar seal ended.
Adlam's vehicle slid down a bank and into oncoming traffic. His vehicle collided head-on with Paul McMahons' vehicle. Te Rihira died at the scene and Mr McMahon continues to suffer health issues from the accident.
