Hawke's Bay Shares Cyclone Silt, Slash Lessons With Flood-hit Tasman
The head of the $228 million silt removal programme after Cyclone Gabrielle in Hawke's Bay is drawing 'eerie' similarities with Nelson Tasman region, as the flood-hit areas look ahead to their own recovery.
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.
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.
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.'
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.

Hakanui flood resilience project set to start on SH2 near Te Karaka, north of Gisborne
Bayley said in the past this stretch of road had to close during heavy weather events because the area was prone to flooding. 'These closures create disruption for communities and the flow of freight, as well as causing safety risks for emergency services. 'To reduce the risk of future flooding, we're raising the highway and upgrading drainage, making it stronger, safer and more reliable for everyday travel and emergency response. 'The Hakanui Straight project spans a vital link for freight between Bay of Plenty and the East Coast, and ensuring its resilience is essential for businesses, residents, and regional connectivity.' The improvements being made are particularly significant for Te Karaka residents, who suffered severe flooding during Cyclone Gabrielle when water breached the stopbanks of the Waipaoa River. In the early hours of February 14, 2023, around 500 residents evacuated to surrounding hills, watching as the floodwaters overtook their homes, workplaces and marae. Te Aitanga-a-Māhaki kaitiaki Pimia Wehi said working with Trec throughout the design process had been crucial in ensuring the upgrade met the community's needs. 'This is a huge step forward for Te Karaka, Puha and Whatatutu. 'The devastation of Cyclone Gabrielle is still fresh in our minds as families lost their homes, businesses were destroyed and many of us were stranded without communication for more than a day,' Pimia Wehi said. 'Seeing this work begin is a relief. It means our people will have better access to emergency routes and won't have to face being completely cut off again.' Bayley said early enabling work, such as the site office establishment, fencing and services relocation, was expected to begin this week, weather permitting. 'Road users aren't likely to notice too much activity until the physical work begins, which is expected next month. 'At that stage, short traffic delays are expected while crews carry out the upgrades. 'Traffic will be managed by closing the road shoulder during early works, followed by one-lane closures with stop/go to maintain two-way traffic during major works with reduced speed limits along the work site. 'Please drive to the conditions and be aware of the increased truck movements and trucks crossing the road.' About the name Hakanui Straight The project name is Hakanui Straight but was formerly Nesbitt's Dip. The change has been requested by hapū and iwi representatives as the name reflects the area's cultural and historical significance. The Hakanui Stream was important for local food gathering, mahinga kai and as a travel route for waka. With the road being elevated to ensure safer and quicker evacuations during floods, Straight (rather than Dip), embodies strength, directness and a clear path forward. For more updates, go to
