"Police officers have then initiated a pursuit with lights and sirens."
The chased vehicle lost control navigating corners and struck a traffic management worker, who was with a team working on powerlines.
It appeared the three occupants of the vehicle took off after it stopped.
The police car stopped by the stricken worker and an officer provided first aid until emergency services arrived, while the second police officer chased the driver.
The worker, aged in his 20s, was flown to hospital in the Westpac Rescue Helicopter in a serious condition. He has since been released.
The teenager will appear in the Hutt Valley Youth Court on Wednesday.
He is charged with reckless driving causing injury, failing to ascertain injury and failing to stop.
