Flood damaged river stopbanks are being urgently repaired by Tasman District Council ahead of more wet weather that was forecast for the end of the month.
The region
has been slammed with two major floods
in the past two weeks and Earth Sciences New Zealand is forecasting more wet weather for later in July and into early August.
The council's river manager David Arseneau told RNZ a key priority was fixing an area of stopbank at the top of the Wai-iti River.
"The whole stopbank just got scoured out over about 150 metres or so, we are actively out there rebuilding firstly the ground that the stopbank used to be on, and then the stopbank - before the next weather event comes in," he said.
Council workers had been out in boats surveying the river network and assessing the damage.
Another area that had been hit was on the Motueka River around Peach Island, where the stopbanks overtopped.

"They've survived and stood up. So right now we are planning out what that repair job looks like and also looking forward to an upgrade and strengthening... it's the same with the Brooklyn stop banks as well," he said.
In many areas of the Tasman District, rivers have massively widened and realigned through paddocks and farms, Arseneau said.
"In the short term we are just not going to be able to solve those issues on any kind of scale before the next flood or the flood after that.
"It's a multi-year recovery that we are looking at for property damage and the impacts on our rural communities."
The rivers had completely changed, he said.
"They are no longer the rivers they were three or four weeks ago. When big events like this come along, the rivers flex, adapt and change... then they'll hopefully be relatively stable for a few decades."

The Nelson Tasman region had begun transitioning from
a state of emergency into recovery mode
.
As of Wednesday, 10 homes have been red stickered, 42 yellow stickered and 48 white stickered, which meant further assessment was needed.
Nelson Tasman Civil Defence is providing accommodation for 12 people following both floods.

Hawke's Bay shares cyclone silt, slash lessons with flood-hit Tasman

Communities across the top of the South Island were facing millions of dollars worth of damage to roading infrastructure, farmland and properties, following the two recent floods that struck the area within a two week period, from late June. Riverside properties in Tasman were grappling with woody debris, silt and waste strewn across their properties. Cyclone Gabrielle smashed Aotearoa in February 2023 with a force of heavy rain which caused flooding damaging infrastructure, properties and land on the North Island's East Coast. Thick silt and upended tractors lie at the front of Pheasant Farm, Esk Valley, in the wake of Cyclone Gabrielle. Photo: RNZ / Jemima Huston Twelve people died during the natural disaster. Large amounts of silt, forestry slash and waste were swept across the whenua, prompting councils across Hawke's Bay to set up an immediate regional taskforce to deal with the material. Shane Fell says the floodwater left more than 500 tonnes of silt on the property. Photo: Supplied Taskforce lead Darren de Klerk said watching the news, there were similar scenes in Tasman as there were in Hawke's Bay and Tairāwhiti following the cyclone. "It's quite an eerie similarity, I think when you look at some of the woody debris and some of the silt and mixed product that we had to deal with," he said. "Obviously, productive land is another similarity in the fact that a lot of the highly productive horticulture and viticulture land has been infected." De Klerk said after an emergency, the early stages of recovery were usually shrouded in uncertainty. "In the early days, anyone dealing with this will find it quite overwhelming," he said. "Firstly, it's just understanding the level of involvement that either Civil Defence or the council has in this recovery." De Klerk said it broke Hawke's Bay up into six zones, triaged properties by severity, and then mapped out sorting and disposal sites, in efforts to "chomp the elephant" one bit at a time. Since its beginning, the team moved more than 2.5 million cubic metres of silt across more than 1100 properties, returning around 7000 hectares of land to productivity. It cleared one million cubic metres of woody debris across the coastline and rivers, and sorted through 12,500 broken orchard and vineyard posts. He said in Hawke's Bay, councils had to "take a leap" to support their communities, before the first round of government funding was announced several months after the event, in May 2023. "Essentially, you don't have a rule book," he said. "From a community point of view, I can guarantee you the people behind the scenes are working as absolutely as hard as they possibly can to find solutions." Photo: RNZ/Samuel Rillstone He said it was working with Tasman officials to share insights and avoid "re-inventing the wheel". "One of the biggest probably learning is just how you manage your contractor army," de Klerk said. "Having a standby list of contractors available, so you're not having to work through the procurement and contracting of suppliers in the heat of the recovery phase. "My thoughts are with them and they'll be trying their absolute best." De Klerk said the work must be methodical, and open communication with locals was vital. He was now working for the Hastings District Council on its ongoing water and roading infrastructure cyclone recovery.

Playground fence sparks anger from Canterbury parent
Amanda Burrows says the installation of the fence as a safety barrier between the Proctor Park playground and swales is "a complete overreaction" from the Ashburton District Council. Photo: LDR/Jonathan Leask A Tinwald mother says the almost $10,000 fence built between a stormwater pond and playground is an overreaction by council staff. Ashburton district Council installed the fence this month after fears were raised about a [ child drowning] due to the playground being built so close to drainage ponds. Mother-of-two Amanda Burrows, who lives opposite Proctor Park, said the new fence is "a complete overreaction". Local residents are unsure about what the fence will stop, she said. "We don't see the point of it," Burrows said. "I can see the logic to some degree, but it feels like a waste of resources that could have been invested in other safety issues around town." Burrows said the situation "feels like PC gone wrong". "I get wanting to protect our children, but it feels like a world gone mad ... will we start fencing off trees to stop kids climbing them in case they fall out?" The council agreed to install the fence in response to concerns about the drowning risk of the swales, which are grassy areas used to manage stormwater run-off. It followed drainage issues at the swales, which required a pump to remove the water after heavy rain. Peter King raised the alarm, saying he felt that a child could drown because the playground was built just metres from stormwater drainage. Councillors discussed the issue at the three waters committee on June 25, where it was acknowledged King wasn't the first to raise concerns. Mayor Neil Brown and councillor Carolyn Cameron both recalled a site visit before the new playground was built when the location next to the swales was questioned. At the committee meeting, it was agreed to build the fence as an immediate solution to reduce the drowning risk. However, some of the neighbours of the park don't see the same level of risk. Burrows said the playground is rarely used by younger children. "It's more of a teen playground. "There isn't a lot there for the younger age children that would be at risk of drowning when the swales have water in them." As a teacher, Burrows said she understood the need to mitigate risks, but it would be easier and cheaper to extend the existing garden at the edge of the playground "They just needed to extend that out, and it would look far nicer than what they have done." Council infrastructure and open spaces manager Neil McCann said the permanent fence installation cost $9500. The existing garden wouldn't be extended as the money has already been spent on the fence.

Weather: Hundreds of properties without power after severe gales in Northland
Severe gales downed trees and powerlines across the region. Photo: RNZ / Rebekah Parsons-King Hundreds of properties are still without power after severe gales ripped through Northland. The wind downed trees and powerlines across the region on Thursday, lifting the roof off one home and flipping a truck and trailer near Dargaville. At its peak, there were thousands of properties without power, but on Friday morning that's down to nearly 500 - most of which are in Tinopai, a coastal settlement on the Kaipara harbour. Fire and Emergency said it attended 11 weather-related calls in Northland, all before midnight. Top Energy's website showed about 140 properties without power in the Far North, but it was unclear whether that was due to the high winds. MetService said more settled weather was forecast for Friday. Sign up for Ngā Pitopito Kōrero , a daily newsletter curated by our editors and delivered straight to your inbox every weekday.
