NZTA asked motorists to delay their journeys.

A detour was now in place.

Motorists heading to the waterfront from the Northwestern Motorway were asked to use the Southern Motorway, exit at Newmarket and head north to get back to the port area.

Those travelling on SH1 towards the port should exit at Fanshawe St or continue southbound and exit at Gillies Ave, then take the on-ramp immediately to head north.
