Wellington's road and rail networks have largely recovered from the deluge that cut the capital off from the rest of the country, but problem areas remain.
After heavy flooding on Tuesday, both State Highway into the capital were open on Wednesday morning, although SH1 is down to one lane between Pukerua Bay and Plimmerton because of slips.
SH58, the Haywards Hill Rd, remains closed, as does Grays Rd, which runs north of the Pauatahanui Inlet.
An earthquake-damaged eight-storey building, at 61 Molesworth St, has forced the closure of that part of the road and nearby buildings may be telling staff to stay home.
The closure may cause problems for commuter traffic.
"If you don't have to come into the city and can work from home you should discuss this option with your employer - but, the city is still open," the Wellington City Council says.
Train and bus services were largely back up and running, although Kapiti trains remain disrupted.
Tuesday's rain submerged the roundabout at Plimmerton and the northbound lane of SH2 north of Ngauranga resembled a canal when it was closed.
