The driver of the other vehicle appears uninjured but has been transported by ambulance to hospital for observation, police said.
The road was closed while the scene was examined.
NZTA said the road had reopened as of 4.30pm, but drivers could expect delays in both directions.
Police officers were last year instructed to change their approach to fleeing drivers, only pursuing the drivers if there is a threat before the start of the pursuit and if there is a need for the driver to be apprehended immediately.
Figures show there were more than 30,000 police pursuits initiated between 2008 and 2019, resulting in hundreds of crashes and the deaths of 79 people.
They also show pursuits are most likely to happen overnight between 10pm and 6am, and crashes are more likely at night.
The majority of fleeing drivers are young males, many of whom are driving stolen cars.
