IRB boats are being used to help evacuate residents in parts of Gisborne as wild weather caused flash flooding and rivers to rise rapidly.
At 2pm the district council broadcast the alert after concern about threatening river levels, and flooding around homes in Gisborne and further north up the coast.
A search and rescue squad including three IRBs and 15 volunteers were pulling their boats into the water about 4.30pm.
Already a month's worth of rain has fallen in a day, with officials waiting nervously ahead of high tide which was due at 6pm. Some areas in Gisborne received over 200mm of rain in the past 24 hours.
Three welfare centres have been set up at Wainui School Hall, the Salvation Army and the House of Breakthrough, with Te Poho o Rawiri Marae on standby.
The Gisborne suburb of Sponge Bay has its power turned off for some time but has now been restored.
Strong winds have also left a trail of destruction across the Bay of Plenty and Waikato, with high winds toppling trees and powerlines across the two regions.
Stoltz said there are already teams on the ground clearing roads of slips.
"Even though work is happening on the ground, we will still need to take a good look tomorrow because we might still be in the situation."
State Highway 1 is now closed between State Highway 29 and Karapiro Rd after numerous trees fell today, blocking the road. The route is not expected to reopen until tomorrow morning.
Stoltz advised residents to treat all water as if it was contaminated but said tap water was safe to drink.
Tairāwhiti Civil Defence group controller Dave Wilson urged locals to stay home.
"There is a problem with rubberneckers, particularly around Sponge Bay, and we really ask that everyone restrict their travel," Wilson said.
"If the river levels around you are rising, or if there are floodwaters getting into your home, please get in contact with us at Civil Defence.
The Gisborne District Council said there had been 220mm of rain since yesterday morning and its team had a busy night monitoring the city's sewerage and stormwater systems.
The storm, which struck overnight, left residents crossing their fingers earlier today as river levels rose.
Rural resident John Fraser is thanking his lucky stars after a near-brush with death.
John Fraser was working in his shed yesterday when a 30m gum tree fell on it.
"The tree fell down and demolished the shed at about 1pm and destroyed everything in it."
About 9pm last night another tree came crashing down, bringing with it a third.
Fraser said the first tree had uprooted the second, "so three trees fell".
"The gum tree that fell needed a crane to lift it off. The tree went through the shed and brought down the rails of the veranda of our house.
"I was in the shed when I heard it creak and I ran out at probably twice the speed of sound."
Fraser said he tripped as he was running out but managed to pick himself up and run to safety.
"I had got far enough just to the edge of the shed when it came through.
"What happened was a small branch fell on the roof, which made me look up and then I saw the tree coming towards me and I took the run. And I saw it completely flatten the shed.
"I told my wife I'm glad it didn't fall on my head.
"I spend a lot of time in the shed so was there but luckily enough it missed me. I am always in the shed messing around. Every man needs a shed and now I haven't got one."
King Rd resident Larissa Wooding-Ngata was today keeping a close watch on river levels, worried for her property.
"It's crazy how quick the river came up," she told the Gisborne Herald this morning. "We went to bed last night and the river (Taruheru River) wasn't spilling over and then I woke up at 5.30am or 6am and it was at our doorstep (base of the steps).
"If I'm standing in the water, it is 30cm deep, right up to my gumboots ... but it's getting worse now as it looks like a big swimming pool.
"We have two rain gauges — one full and one empty. It measured 90mm yesterday and now it's about 200mm now."
"We managed to screw the loose roofing down and keep it intact," a senior firefighter said.
Fire and Emergency NZ sent two of the professional Gisborne staff to Tikitiki yesterday, and two to Tokomaru Bay to assist firefighters in those areas of the Coast if needed.
Uawa Civil Defence reported on Facebook that surface flooding at Anaura Rd had cut some properties off.
"Local advice is that Rototahi has flooding and only 4-wheel-drive vehicles or better should be trying to get through.
District Court sessions in Ruatoria were called off today.
Court staff made it partway to Ruatoria but it was decided to reschedule the court session due to road conditions.
Heavy rain meant Gisborne District Council had to open the emergency sewer valve at Wainui Rd into the Turanganui River at 5.40pm to prevent sewage from overflowing back into homes and on to roads, and causing a significant health risk,
"The discharge is highly diluted with rainwater, but still poses a health risk," a GDC Facebook statement said. "We'll notify the Hauora Tairāwhiti Medical Officer of Health, water user and sports groups.
"Temporary warning signs will be installed and we advise no swimming, fishing or gathering shellfish in rivers and beaches until at least five days after the valves are closed and warning signs are removed."
Sewage worries kept some Ilminster Intermediate students away from school today.
"Whānau, an unusual request from us. If your child is at home at the moment, can I please request that you keep them at home," principal Megan Rangiuia wrote on Facebook.
"Whilst we are not closing, we have very full sewage pipes at the moment and we are conscious of managing that until the rain abates a little."
On Facebook, parents were understanding. The school postponed assessments for today so absent students did not miss out.
In Wairoa, high river levels closed two back-country roads at Hereheretau and Kotare roads.
A MetService New Zealand post on Facebook said Gisborne Airport recorded its second wettest 9am-9am period on record since 1937.
"95mm in 24 hours is a lot for an urban centre, especially when their average November total is below 65mm."
At 11.25am, GDC issued a flood warning for the Hikuwai River. The Willow Flat gauge showed the river level as 8.12m and rising, expected to peak at 8.5m at 1pm.
