Auckland is waking to a murky start to the day with fog shrouding much of the central city this morning.
Tropical humidity is causing a combination of low cloud, fog and mist to cloak western and inner city suburbs in a thick white blanket.
Traffic authorities say the fog is affecting visibility across the city but so far there have been no major disruptions. Motorists are being warned to turn headlights on and take extra care on the roads.
A cargo truck and bus had crashed on Beach Rd in Parnell, leading to delays for traffic in the area.
