There was also a crash affecting southbound traffic at the Hill Rd off-ramp. The crash has been cleared but traffic was backed up to Highbrook.
The NZ Transport Agency is expecting heavy traffic and delays as the afternoon peak period builds. It thanks motorists for their patience and advises them to delay their journeys if at all possible.
