Residents of the Wellington region inundated by torrential rain and flooding this morning are taking stock before more rain arrives this afternoon.
But roads, homes and businesses in Kapiti, Porirua and Hutt Valley have been seriously flooded in many areas.
An elderly man has died in flooding in Wellington today as torrential rain and slips caused transport chaos and cut the city off from nearby communities.
As rivers and streams burst their banks, roads, homes and businesses in Kapiti, Porirua and the Hutt Valley were seriously flooded in many areas.
Police said officers searched the area and found the man's body in flooded water near his vehicle.
There were no suspicious circumstances relating to his death.
Police said they were working to notify next of kin and the death had been referred to the coroner.
Meanwhile, police said all motorists should take extra care and expect delays as conditions were "still treacherous with extensive flooding in many areas" around Wellington.
Police said they would work diligently through the night to ensure the safety and wellbeing of communities affected by the Wellington floods and stormy weather.
They said police and other agencies would continue to monitor the situation overnight and had contingency plans in place ahead of tomorrow.
"We can also reassure the community that we have sufficient resources in place to respond to any other events."
Drivers have been advised to stay off Kapiti and Hutt Valley roads this evening wherever possible. Motorists were also asked to reconsider their normal commuting patterns ahead of tomorrow.
"We encourage motorists who may be planning their commute to work in the morning to think twice and use alternative transport if available."
Members of the public should call 111 if they had concerns for their safety.
More disruption for Friday am commuters
Civil Defence staff said more disruption was expected for commuters tomorrow morning.
Wellington Region Emergency Management group controller Bruce Pepperell said commuters planning to travel within the region tomorrow should consider alternatives to their usual morning commute.
Train services would be suspended until "further notice" according to a tweet by Wellington City Council, which is likely to result in road congestion.
The New Zealand Transport Agency was advising people to "plan around" congestion and if possible work from home, travel outside of peak times, or commute on foot or bike.
Mr Pepperell said Wellingtonians handled today's flooding and subsequent disruptions admirably.
"The weather has resulted in some inconvenience but it has been a great opportunity for people to put into practice their emergency arrangements and check what works," he said.
"We had four emergency welfare centres operating on the Kapiti Coast and two centres in central Wellington. The fact that they were not needed is testament to the way people have rallied together and looked after themselves and each other."
Rains and floods cause transport chaos
As the morning commute started today, a slip blocked part of State Highway 1 on the Kapiti Coast.
Commuter chaos followed as the highway between Paekakariki and Pukerua Bay was closed and detours were off-limits as slips and flooding struck the Paekakariki Hill road.
The morning misery intensified as streams surged and some residents had to leave homes in Moa and Tui roads in Raumati.

The Emergency Management Centre in Paraparaumu was activated and an evacuation centre set up at Te Newhanga Kapiti Community Centre, with Raumati South School on standby.
In Lower Hutt, flooding hit the city's main road before noon. Workers were on the street as waters rose and roundabouts were submerged.
Coronation Coffee owner Indra Sinnathambi said he'd never seen a deluge so severe.

Professionals real estate employee Gareth Barlow said water was knee-deep on the street and seeping inside his office.
"There's a 5m pond in front of us. People ... have had to take their shoes and socks off and roll their pants up to wade out," he said.
For children of Mazengarb Rd, a regular school day was replaced with stomping, splashing, and free boat rides.
"It was actually really fun to have all the neighbours in one place saying hello to each other," local mother of four Jacqui McKenzie said. "How often can you row down your street on a boat?"
The deluge forced the Kapiti council to offer sandbags to affected households. It was soon clear the sandbags were in short supply.
Otaihanga resident Alastair Beissel spent the morning sand-bagging his and nearby properties.
"I went out and grabbed whatever I could, like potting mix bags and put them round the house to keep the water out," he said.
Nearby, Vivienne Bould put sandbags around her house and had a load of sand dumped on her driveway.
"The sewage pumps aren't working. I don't know whether that's because the rivers have flooded into them up."

On the Waikanae River, which burst its banks, a man was rescued on the bucket of a digger. Kapiti mayor Ross Church said the man was trapped in mud.
The capital's central library on Victoria St also offered a place to stay for people stuck in the city.
At 6pm, Library staff had started preparing coffee and tea for guests in the mezzanine.
Mayor Celia Wade-Brown said parking officers would only ticket clearways and safety related offences for the rest of the day.Wellington Electricity said some customers would remain without power overnight.
Some homes in the Takapu Valley area east of Tawa and the Ohariu Valley to the west were without power at 4pm.
"We've seen some poles taken out in the rural areas by floodwater so that's why those customers will remain off overnight," a Wellington Electricity spokesman said.
Police deployed specialist teams and off-duty staff to the Kapiti, Porirua and Hutt Valley areas and were preparing for further rain as a high tide loomed.
The biggest downpours were expected in the Tararua and Ruahine ranges overnight.
Stream flows were expected to slow down overnight but bigger rivers could keep rising for hours as rain ran off from watersheds, WeatherWatch forecasters said this evening.
Conditions were expected to be unsettled tomorrow, but not as wet as today, WeatherWatch predicted.
Man rescued from muddy banks
A man had to be rescued from the muddy banks of the Waikanae River on the bucket of a digger, Kapiti mayor Ross Church said.
The man had been trapped in mud beside the significantly flooded river, he said, and police coordinated the rescue with the help of a digger.
"That's one of the messages we're trying to get out is people please stay away from the water, the rivers and the mud because there's a lot of serious flooding," Mr Church said.
"The last thing we need is people going to have a look and putting themselves and the emergency services in danger."
Future outlook
Surging streams will slow down overnight but bigger Wellington rivers could keep rising for hours as rain runs off from hills, WeatherWatch forecasters said this evening.
Conditions were expected to be unsettled tomorrow, but not as wet as today, as WeatherWatch predicted showers and cooler southerly winds to pick up in the afternoon and evening.
The forecasters expected "strong to gale force southerlies and a few showers" on Saturday, easing by the evening.
