Motorists in Auckland central are in gridlock following a faulty gate system leading on to the Northern Motorway from Fanshawe St.

The New Zealand Transport Agency is reporting the Fanshawe St on-ramp is currently closed because of the gate which is causing delays.

Traffic is also heavy approaching the Harbour Bridge for northbound motorists, then between Tristram Ave and Upper Harbour Highway.

A bus passenger has been stuck next to Albert Park for the last 40 minutes, claiming it's "rush hour madness at the moment".
