Emergency services were called just before daybreak and the family was full of praise for the prompt response.
"The Runanga brigade was just awesome,'' Tamare Stollery, mother of six, said.
"I just got off the phone and they were here,'' daughter Sarah said. She was piggy-backed through the water by a fireman, and then up the bank to the highway.
"The little ones (aged two and four) were a bit upset, but they were soon cheered up with some lollies from the firemen,'' she said.
The family switched off the power to the house when they noticed water coming up through the floorboards.
They were keeping an eye on the water level about 4am as the rain was bucketing down, and soon decided to call the police.
The family had only moved a few weeks ago from Blackball to their new home at Coal Creek. Uninsured they had lost everything, including another family member's property that was stored in a garage.
The family was taken to the Runanga fire station, where they were given breakfast, and were later taken to stay with relatives on the Coast Road.
Meanwhile, near gale force winds lifted roofs in Greymouth, snow fell at Blackball and Jacksons, and Arthur's Pass was completely cut off in the first polar blast of winter. There were reports of sleet in Boddytown and Cobden, where floodwaters were also causing problems.
Ross, Harihari and Whataroa schools were all shut by high winds; in many cases the school buses could not get through, and the power supply was coming and going.
The Runanga Takeaways was the first call-out for the Cobden, Runanga and Greymouth fire brigades, when about 10cm of water went through the shop.
Bryan Blanch said they were open as a dairy this morning, but could not cook.
"We got flooded out from the creek next door, which blocked up. There's a lot of cleaning.''
Families and young children were evacuated to the Runanga fire station about 8.30am after severe flooding in Ward Street, Runanga, and around the Camp Creek overbridge, at Coal Creek.
Cobden fire chief Gary Pollock said that with water blocking access to homes in the McLeans Pit area, firefighters had to walk around the rear of the properties to help the owners carry their pets to safety.
Transport operator Cliff Sandrey said he used a loader to get Spring Creek miners across the flooded Coal Creek and back home again after their shift ended.
Other call-outs included to a window that was blown out in Bright Street. Flooding was particularly bad in Peel, Hall and Ward streets.
Grey District Mayor Tony Kokshoorn authorised contractors to open the 'cut' in Cobden, allowing backed up floodwaters to escape to sea.
Range Creek, running through the middle of the suburb, burst its banks.
Mr Kokshoorn said the water was about "one foot under some houses'' and more rain was forecast.
"I'd rather be safe than sorry,'' he said.
In Greymouth, Kidsfirst Kingergarten in Shakespeare Street was closed, and the Greymouth Star lost part of its roof and a roller door buckled in the strong winds. Trampolines went flying _ including two in one street _ and Mawhera Quay was closed for a time while firemen secured the roof and frontage of an old second-hand shop, which threatened to collapse.
Grey District Council civil defence emergency manager Allan Wilson said they were worried about the parapet and were having it assessed.
Department of Conservation staff at Arthur's Pass said 15cm of snow had fallen overnight, and by mid-morning it was still snowing. With Porters Pass also shut, the alpine village was quiet this morning.
Ross School principal Shane Baillie, who lives nearer Hokitika, could not get past the weighbridge south of Ruatapu.
"There were trees down, the contractors were busy working on that,'' he said.
State highway 6 and the school were both shut at Inangahua Junction. By 9.30am the red marks at the top of the roadside pegs were all that were visible between the turnoff for the State highway and the village. It meant travellers could get from Reefton to Westport, but not Reefton to Murchison and Nelson.
Greymouth weather observer Phil Forrest recorded 147mm of rain in the 24 hours to 9am today. Kumara had 90mm by 7am.
The NZ Transport Agency was more hopeful of reopening Arthur's Pass at lunchtime, than it was of opening the Lewis.
"Our guys have been working through the night in continuous shifts. De-icing agent had been put down, which will help us to remove the snow,'' West Coast senior asset manager Mark Pinner said.
Further up the coast, fifty sandbags remain in place in Murchison, but flood waters appear to be receding, according to the Nelson Tasman Region Civil Defence and Emergency Management Group. Flooding on Faifax and Hampden streets affected one commercial property, one residential property and the recreation centre, however this has been cleared.
Civil Defence said there are also a few slips have been reported around Longford and hills in Murchison, but no roads or property is in danger.
In Nelson, Isel Park is closed due to windy conditions and the risk of falling tree branches. Tahunanui Reserve back beach is also closed due to storm tide debris and risk of falling tree branches.
Winds with gusts up to 130kmh are forecast to lash the Tasman region
Snow has been reported in Rappahannock, Matakitaki and Tophouse, but not at a level to cause concern. Korere-Tophouse Road was closed near Tophouse after a truck and trailer unit lost control in about 10-40mm of snow, blocking the road.
