The heavy rain may have ceased but a dozen Greymouth residents are still stranded after flooding damaged their homes.
Greymouth was hit hard by heavy rain that measured up to 170mm following a long period of drought.
The torrential downpours caused surface flooding that prompted evacuations on Thursday.
Grey District Mayor Tony Kokshoorn said a dozen people were still staying with friends and family on Friday but that it wouldn't take long to get them back into their homes.
He said the town was quickly drying up and it was business as usual in the town centre, which was hit hardest by surface flooding.
Meanwhile on the East Coast the wet weather has led to slips on State Highway 1, north of Kaikoura.
NZ Transport Agency has closed the highway between Mangamaunu and Clarence, with detours in place.
The rain is easing in some parts of the South Island, unfortunately for the Nelson-Motueka area, the bad weather is headed their way.
The weather forecaster has issued a heavy rain warning for western Nelson, not including the city, from midday Friday to Saturday.
Between 100 and 120mm of rain is expected, which could cause some surface flooding and slips.
