The driver of the car was extracted from the vehicle and taken to Auckland City Hospital in a critical condition.
Two northbound lanes were closed while the Serious Crash Unit conducted a scene examination, said the spokesperson.
At 7.20am, the New Zealand Transport Agency (NZTA) said the Coronation Rd off-ramp is closed and advised motorists to “pass with care and expect delays” earlier this morning.
One lane has reopened, leaving two available for traffic, it said at the same time.
“Traffic is heavy as far back as the link from SH1. Consider an alternative route, delay travel or expect delays.”
