The rain settled down in Dunedin and "the city fell down," but the flooding surfaces are still widespread.
Forecast for the area is during the low rainfall, which should help in the discharge of flood waters.
Dunedin Mayor Dave Cull said the Council and Civil Defense Service would remain "in a state of alert" tonight, before clearing in the morning.

"The heavy falls that were anticipated took place around 4 pm and they started to descend. We generally expect that things will continue to improve, and maybe maybe around some rivers."
* Snow falls to 400 meters overnight, as a strong cold south of South Island
* MetService: conditions perfect for 100m high Canterburi tvister
* Tornado strikes Mid Kenterberi, after a day of wild weather
The Taieri River continued to grow, said Cool. Residents in Middlemarch and Henleigh were particularly affected by flood waters.
"There will be a few people who are a little uncomfortable, who had to leave their homes, but in general the city turned everything."
It was not necessary to declare a state of emergency, said Cull. However, he expressed concern about the city's ability to deal with difficult weather conditions.

Relaxation in South Dunedin, after a dive, leaves the city overflowing
"It's clear that our infrastructure is not designed for this intensity. The extent, if dispersed over time, can be managed."
EVAKUACIJE, ROKOVI IZLOŽENI
Dunedin residents are still invited to leave the roads where possible in the city and Taieri lowlands.
Earlier, one person was released from the car after being stuck in waterbursts near Kaitangata in South Otago. The police were alerted around 4.50 near the intersection of Lakeside and Stations Rd, Lovells Flat, between Balclutha and Kaitangata. The man was under the train's overpass when he was in trouble. He was saved without injury.
Most of the highways were opened on Tuesday afternoon, but many warnings are in force, a spokeswoman for the Transport Agency NZ said. Once on the South Island, it was closed on Tuesday afternoon – the state highway 90 from Raes Junction to Tapanui – because it partially fell out. SH8 from Rockburgh to Millers Flat is closed in the morning due to floods, but reopened for about half a day.
The state highway 1 south of Milton was not closed on Tuesday afternoon, as the police initially advised, but it closed from Tuesday night for cars with only a four-wheeled vehicle, due to the large floods between Milton and Balclutha. There were warnings for other Otago highways due to slides, strong winds or surface waters.

Heavy rains cause flooding areas and problems with the wastewater system around Dunedin on Tuesday.
The Civil Defense Corps of the Dunedin City Council, Sandi Graham, said widespread flooding still existed around the city on Tuesday, and people should avoid a non-essential trip.
"Not all floods are marked. If it is necessary to drive, please reduce the speed through the flooded areas so that the water does not push into the properties."
Hennley residents used to knock on the door and advise them to evacuate as the rain rises. In the meantime, all residents of Dunedin have been invited to reduce the amount of showers and use washing machines, as the continued rain has exerted pressure on the wastewater pipes and pumping stations around the aquatic city.
Stanari Mosgiel and South Dunedin, who were worried about floods or who had problems, can still collect bag bags with different locations, including the Taieri Memorial Park and the parking lot, the Mosgiel car park and the Dunedin Children's Park Park.
Three streets in Middlemar, Otago, were previously closed due to an increase in the wastewater network. The pump was used to provide additional capacity, while the area was hit by heavy rain, said a spokeswoman for the City Council in Dunedin.
VETTEST DAY OF MONTH
MetService Meteorologist Andrew James said that Dunedin had experienced its coldest day of the month, 47.7 millimeters of rainfall, with a maximum daily clock of 10.6 millimeters.
"When we talk about rain rains, about 6.5 mm per hour, so it's really damp for Dunedin today," said James.
Low pressure north of Dunedin is moving, but it is expected to remain windy overnight, especially on the coast.
The parts of the Southern island were returned in winter, with closed roads and issued snow alerts.
The Otago Regional Council opened the Riverside Riverside River Tauri River in Outramon on Tuesday afternoon to divert water into the area located at the foot of the Taieri Flood Protection Scheme in order to reduce the effects of floods on properties underneath the river in Henley.
Director of Science, Danger and Engineering Dr. Gavin Palmer said that the level of the river continues to follow around Otago. "At this moment, there is no spill from Silver Stream, which is positive. We will take care of this because, although it has fallen, it is susceptible to precipitation.
"We are also following the Mill Creek pumping station, which was under pressure during the July 2017 flood and brought additional stabilization material, if necessary, although we do not expect any problems," Palmer said.
They also follow the Dunedin Rivers, especially the Water of Leith near Leith Street Central and Lindsai Creek on North Road.
FLOODING IN SOUTHLAND, SNOV AND CANTERBURI
Further to the south, some schools were closed in northern northern and western and southern Otago, and Blue Mountain College in Tapanui remained open, but students who passed public exams were warned only to travel to school if they could be safe.
The New Zealand Qualifications Authority (NZKA) says that students who can not attend their exams due to time will not be in a disadvantaged position.
More than 30,000 students across the country have scheduled exams on Wednesday. The grades will be offered to students who can not take exams due to floods, snow or road closures.
"The students spend many hours preparing the exam, so we try to ensure that the examination centers are open if the students are able to get there safely," said NZKA Deputy Executive Director Grant Klinkum.
On Tuesday night, the Bruce Civil Civil Defense team in Milton was playing waiting after the storm caused isolated floods in the city of South Otago.
Milton's fire brigade volunteers and member of the civil defense team, Warren Tait, said they had "about five calls at 4 pm as the situation worsened, people were pouring in acacia." Several houses are in danger, he said.
On the main street, Tokomairiro Communiti Hub with floods has been flooded and cordoned off. A civil defense team member, Jill McIntosh, said a flat that searches for bags and reports that their toilets are backed up in the center for providing District Council Clutha.
Team Coordinator Allan Philips said on Tuesday night and Wednesday morning he would evaluate the weather and water levels of the flood waters. Emergency centers were set up and the rest would be open to Balclutha and Lavrence, while the situation could not be re-evaluated.
The Southland Environment has previously triggered flood alerts, and the Clutha District Council issued a warning to users on rural water plans in Tuapeki West, Glenkenich and North Richardson in order to water the water due to distant rain and floods.
Earlier in the day, around lunch Tuesday, most of the rain was concentrated in the Canterbury region. MetService also received a report on good snow conditions during the morning of Castle Hill Hill, Christchurch land on the west side of Porters Pass. There were also snow reports from Ranfurl and Rockburgh in Central Otago.
MetService meteorologist Lisa Murrai said the low low level lies in the east of the country, south of the Banks peninsula. "In the clockwise direction around the low, so it's a stream on the land in the lower half of the South Island or southeast or south, so it feels pretty cold there."
At Le Bons Bai on the Banks Peninsula, the lunch temperature dropped to 4.3 degrees Celsius, and the area hit the cold southwest. At 12 o'clock from midnight to midday, Methven recorded 32.8 mm of rain, Timaru Airport was 22.6 mm, Mt Cook Village was about 20 mm and Ashburton was 18.8 mm, Murrai said.
THUNDER, VATERSPUTS FOR NORTHERN ISLAND
On the North Island, there were thunderstorms in Northland, Auckland and northern Vaikutou.
Waters and lightning were also seen on the shores of Auckland beach, near Torbe on the north coast. It is expected to continue "on" on Monday.
Auckland sees extended (2 days) magic of heavy showers, city and thunder. This is unusual for us – and some of the local, short-term rains will be quite intense, especially in the west. Keep that water and eyes on the radar at https: //t.co/7k3nmdVKvk ^ GG pic.tvitter.com/ SIIB0KSI5P2

Meteorological conditions in Canterbury and the upper northern islands were linked, although the currents on the land were from slightly different systems, Murrai said.
"Rain in Kenterbery has additional moisture due to the flow of land. Also, in Auckland, the wind is somehow northwest, bringing warm warm air to the surface.
"Although they get winds from different directions, but we have a huge cold air pool that gives instability … that big cold pool over New Zealand is blowing."
IS THE SNOV RARE IN NOVEMBER?
Meteorological company MetService Claire Flinn has said from 1990 that during the month of November there was a severe snow hazard five times, so that, unusual, it happened once a year.
This snow, wind and rain was caused by a combination of heights south of the South Island and slowly falling to the west, she said.
"With this high seating in the south, it's just making south-east winds on land in Otago and Canterbury, keeping moist weather and snow at those higher altitudes."
High also kept low to move eastward as fast as usual, said Flinn.
"From the highest to the south, the wind extends between that high and low, making the wind pretty strong around the southern parts of the Southern island."
