A heavy rain watch has been issued by the MetService for the southeastern edge of Auckland, Bay of Plenty, Coromandel, Fiordland, Nelson, Rotorua this evening.

A front moving eastwards across the Bay of Plenty is now expected to “reverse direction” on Thursday and move back towards the Coromandel Peninsula, MetService forecast.

The red heavy rain warning for Bay of Plenty, west of Kawerau has now been lifted, but a heavy rainfall watch is now in its place for the possibility of further heavy rain on Thursday.

There is also now a heavy rainfall watch in place for the Hunua Ranges and Coromandel Peninsula. In all these areas, the amount of rain would not normally be enough to justify a watch, but the impact of this rain could be greater due to the recent flooding.

Orange heavy rain warnings remain in place for Bay of Plenty about and east of Kawerau, northern Gisborne and Westland.

Heavy rain watches remain in place for Western Tasman and northern Fiordland.

People are advised to keep up to date with the latest forecasts in case any changes are made, or further areas are added.

Meanwhile, troughs are expected to affect the west of the South Island through to Friday.

Three injured as Auckland bach crushed in slip

Three people have been injured - two seriously - after a bach at an Auckland beach was crushed in a dramatic landslide, one of dozens of slips that have wreaked havoc following more heavy rainfall in the region. Dramatic aerial photos have revealed the utter destruction of the destroyed bach.

Six fire trucks and crews as well as Auckland Airport’s hovercraft with search and rescue personnel raced to the scene of the landslide, at Orua Bay Beach at the Manukau Heads, near the Awhitu Peninsula. One of the three injured people was trapped for more than two hours and was eventually freed about 2.15pm.

• Chris Hipkins: The severe weather created unforeseen challenges

An Orua Bay local told the Herald she understood an elderly couple was among the victims, with a man suffering a badly broken leg and a woman being trapped. Photographs reveal a huge scar in the cliff-face - and indicate a miraculous survival story. A car also lies crushed next to the destroyed bach.

Another piece of good news, for parents perhaps, is that schools in the Auckland region are able to reopen tomorrow. But there is little else to cheer, with news that 168 homes have now been red-stickered.

This morning’s rain had caused many slips, surface flooding and property damage, Kelleher said. Bus and rail services had been impacted, she said, as well as Auckland’s road network. More than 600 cars have been damaged by flooding and 194 are yet to be taken away.

Auckland Council’s Ian McCormick said 95 assessment teams had been deployed across the city, joined by crews from elsewhere in the country. He said more inspection teams were expected to follow.

McCormick said the council was doing 700-1000 assessments per day, with most of them to be completed by the end of the week. He said there had been 168 red-stickered houses as of today.

As the rainmaker moves down the North Island, a massive slip has smashed into the back of a Coromandel home along State Highway 25 near Thames, prompting the evacuation of houses. Auckland’s Tamaki Drive is blocked by a massive slip and the Okahu Bay cemetery has been swamped with floodwaters.

In a u-turn, Auckland Transport has authorised the wiping of all parking tickets issued between 2pm on Friday to 9am this morning. And Auckland schools will be able to open from tomorrow. The Ministry’s Power of Direction has been lifted -- meaning schools can open, at their discretion.

Emergency services earlier dealt with trees that have fallen on homes in Auckland’s Mt Albert and Whitford. A private dam has collapsed on a farm, while torrential rain has brought down more slips and worsened a sinkhole on a key West Auckland road.

Auckland’s Northern Motorway was closed by flooding in both directions between Esmonde and Northcote roads for about 90 minutes on Wednesday, before reopening just before 8am. Other sections of the city’s motorways have also been severely impacted including the Southern Motorway at Greenlane and Ellerslie-Panmure, and the Southwestern Motorway (State Highway 20) southbound between Queenstown Rd and Neilson St. State Highways 1 and 16 further north of Auckland have been closed by slips and flooding.

A caller to Newstalk ZB’s Marcus Lush from Auckland’s Orewa said last night she had been clearing debris from her drains. “Water’s coming up to the door... it’s horrible,” said the woman, who lives near the estuary on Maygrove Dr. “Friday was really bad, I just hope it moves quickly... I’ve already got carpet damage. It’s a bit scary.”

NIWA reported this morning that, in 24 hours, 71mm of rain had fallen at its Western Springs climate station in Auckland - " month’s worth of rain... again”. Much of the rain fell in only a few hours including 25.2mm in one hour, 44.2 mm in two hours and 58.6mm in three hours.

State Highway 1 is closed between Brynderwyn and Waipu following slips on the southern side of the Brynderwyn Hills, and State Highway 16 is closed between Waimauku and Helensville. A sinkhole also opened up in Swanson, West Auckland, last night, taking out power lines.

Texts to ZB’s Marcus Lush from residents in north Auckland last night included: “Pouring and big wind gusts happening in Tindalls Bay, Whangaparaoa”; “It’s hitting the Whangaparaoa peninsula. Very strong wind and rain”; “At Waitoki, about 15km inland from Orewa. Getting pretty wild here now”; “Wind and rain has increased in Browns Bay.”

Northland is now out from under a red heavy rain warning but is still in a state of emergency. Auckland, north of Orewa, is under a red warning until 8am; Coromandel until 4pm and Western Bay of Plenty areas until 9pm. The rest of Auckland, south of Orewa, is under an orange heavy rain alert until 10am. “It’s right over us now,” tweeted councillor Richard Hills. “Please do not hesitate to evacuate if you feel unsafe or if water starts to rise.”

Northland declared a seven-day state of emergency at 1pm on Tuesday - the third region to do so since Friday evening’s deadly storm which has claimed four lives. More than 1000 Far North homes lost power this afternoon, but it was restored for most by 7.30pm. Northland and Auckland down to Orewa remain under a red warning until tomorrow morning.

Coromandel is also in the firing line - a red warning came into effect at 10pm last night - and MetService has extended that to several other areas across the North Island, including Tauranga and Rotorua.

State Highway 2 in the Karangahake Gorge between Waihī and Paeroa was closed by a large slip yesterday afternoon. It has now reopened.

Meanwhile Auckland mayor Wayne Brown has urged residents to “stay home” wherever possible. So far, more than 100 homes have been red-stickered and 375 have been yellow-stickered.

Schools have been closed but the Ministry of Health yesterday afternoon revised its advice for early childhood centres, saying any that can safely open, may unlock their doors for families from today.

An emergency alert was sent to Aucklanders’ mobile phones at 3.30pm. At exactly the same time, new Prime Minister Chris Hipkins announced, from Wellington, that Cabinet had agreed to another $1 million for Auckland’s flood relief fund.

A sinkhole also opened up in Swanson, West Auckland, last night, taking out power lines. Fire and Emergency NZ were initially called to Scenic Drive about 7.30pm after reports of trees falling on the lines. However, upon arrival, they discovered the sinkhole opening up, causing landslides that were taking the lines with them.

One forecaster warned the new rounds of rainfall - caused by the same stubborn subtropical low that brought Friday’s flooding - could bring 100mm to 200mm to parts of Northland, Auckland and the Coromandel in the coming days.

“The very warm and humid air mass covering Aotearoa brings ripe conditions for persistent, heavy rain plus the risk of thunderstorms which can further intensify the rainfall,” MetService meteorologist Lewis Ferris said.

MetService said high rainfalls could cause dangerous river conditions and significant flooding.

“Slips and floodwaters are likely to disrupt travel, making some roads impassable and possibly isolating communities,” the MetService said.

An orange heavy rain warning has been issued for Auckland south of Orewa lasting until mid morning, which could cause rivers and streams to rise rapidly, MetService said.

The fresh tranche of warnings came as Aucklanders used a reprieve in the weather to start cleaning up after the worst of the rain on Friday evening.

The Minister for Emergency Management Kieran McAnulty yesterday announced an extra $1 million of funding for Auckland’s Mayoral Relief Fund to help communities.

“This is the most significant contribution to a Mayoral Relief Fund ever and ensures that funding is being provided to the affected communities as quickly as possible,” McAnulty said.

So far, more than 100 homes have been red-stickered and 375 have been yellow-stickered.

Auckland Council has closed all non-essential community facilities, services and destination sites. This included pools and leisure centres, libraries, community venues, the Auckland Botanic Gardens, the Auckland Art Gallery and cemetery offices.

Meanwhile, schools and other education centres across Auckland have been told they may be able to open within days if the weather improves and roads are cleared.

Yesterday, Secretary for Education Iona Holsted issued a special bulletin for school leaders apologising for “slow” communications yesterday when she instructed schools, kura, tertiary institutes and early learning centres to close.

Holsted said the direction had been “necessary in order for emergency services to work on fixing road infrastructure”.

The Ministry of Education, however, later said early learning services that can safely open, may unlock their doors for families in their community that need education and care from today.

Some 35 Auckland roads are closed or restricted and an entire section of State Highway 25A on the Coromandel Peninsula has been washed away during the intense weather.

Auckland Transport’s Sarah Bryant said since Friday, AT had closed 82 roads, 35 of which remain closed. 47 had been reopened, she said.

There had been 20 slips on the rail network, she said.

Auckland has experienced record rainfall, with widespread flooding creating hazards for people and properties since Friday.

So far this year the National Institute of Water and Atmospheric Research (Niwa) said Auckland has already recorded 38 per cent of its usual annual rainfall - and 769 per cent of its average January rainfall.

This month is also likely to go down as one of Auckland’s dreariest Januarys on the books with the city averaging a paltry five hours of sunshine each day.

Auckland Mayor Wayne Brown declared a state of emergency for the region on Friday night, which came into force immediately and will last seven days.

“Stay home if you can,” Brown said. “The ground is so saturated, that if anything [the coming rain] could be worse than Friday.”

Due to the widespread flooding, slips and extensive damage, some businesses are asking office staff to work from home, while others have closed their doors until further notice.

The New Zealand Defence Force (NZDF) is on standby at two bases in the Auckland region to assist if required.

There are also military liaison officers at the Auckland Emergency Centre, the Warkworth Civil Defence Centre, and in Northland.

“There are a couple of Unimog trucks with supplies at RNZAF Base Auckland available if needed to reach flood-affected areas. Other supplies are at RNZAF Base Auckland if these are needed,” an NZDF spokesperson said.

MetService forecaster Georgina Griffiths told media yesterday the warnings were “on track” and would see rain pummel the upper North Island as predicted.

As well as the red and orange rain warnings, a new heavy rain watch has been issued for parts of Tasman, Westland, Waikato and Mount Taranaki.

Meanwhile, the storm-ravaged Waitomo District Council urged residents to have a grab bag and emergency supplies ready in case they need to evacuate in the middle of the night. The council says a heavy rain watch is in force for the early hours of tomorrow morning.

Waka Kotahi NZ Transport Agency regional manager of maintenance and operations Jacqui Hori-Hoult said contractors have worked hard to clear some slips and debris on SH1 at the Brynderwyns, but because there’s a very real risk of further slipping at any time, they made the decision to keep the stretch closed for now.
