Part of the country's only gasworks museum is at risk of collapse with work to remove the risk expected to start later this week.
The Dunedin Gasworks Museum was closed last month to assess the safety of its 25-metre high chimney stack after possible earthquake damage.
The Dunedin City Council owns the Category 1 historic place, and said a recent update showed the condition was worse than first thought.
The council's property services group manager Anna Nilsen said detailed inspections had been carried out using drones and crane access.
"These show that in addition to the cracks and movement within the structure we already knew about, there is significant localised damage in the upper sections of the chimney that pose a risk of collapse once we start work," she said.

Supports would be installed to secure it and allow contractors to deconstruct it safely while mitigating the risk of an uncontrolled collapse, she said.
"We remain committed to saving as much of the chimney as possible, but it's a complex job and public safety is the top priority."
The council has been working closely with the Dunedin Gasworks Museum Trust

Queenstown Lakes District Council must fix issues with Shotover wastewater plant
Shotover Wastewater Treatment Plant in Queenstown. Photo: Supplied / Queenstown Lakes District Council The Environment Court has ruled the Queenstown Lakes District Council (QLDC) must fix issues with its troubled Shotover wastewater treatment plant. In January, the Otago Regional Council (ORC) sought an enforcement order from the Environment Court to address current compliance issues at the treatment plant. Mediation was the next step in deliberations, and the court released its decision on Monday. It came after two abatement notices and 10 infringement notices were issued since early 2024, many over the discharge of treated wastewater to land on the Shotover Delta . Otago Regional Council chief executive Richard Saunders said the court's enforcement orders would help mitigate adverse environmental effects caused by the plant, and paved the way "to begin a plan of action so QLDC is able to meet its consent obligations and achieve compliance against the court's orders". "The decision and enforcement orders give a clear indication of what's required to operate, remedy and upgrade the wastewater plant, while maintaining transparency with ongoing monitoring of these processes." The decision outlined seven pages of separate enforcement orders, including upgrades, contingency measures, timeframes and milestones to be met. They included an operations and management manual, staff training, sampling and monitoring, repairs and improvements to the wastewater plant, upgrades to the plant and a new disposal field solution. The latter required a consent application be made for a new disposal system by May 2026, which must be implemented by December 2030. Saunders said the regional council had taken several steps since problems arose with the plant's operations, dating back to 2021. He said the council would continue to closely monitor the treatment plant site and undertake its regulatory role. The Environment Court's decision is separate to QLDC making an emergency/retrospective consent application in early May for earlier works at the Shotover site. The emergency works enacted by the district council were to bypass the problematic (soak) disposal field and to discharge treated wastewater directly into the Shotover River. The council was still assessing the application, with a date for public notification yet to be set.

How a motorbike trip sparked a novel set on the Otago
Two years ago, twenty-four graves were exhumed from a property in Lawrence, including one that contained a woman and a young child. The Androssan Street cemetery had been in use since the early days of the goldrush, when Gabriel Read first discovered gold in Otago in the early 1860s. Author Kirsty Powell has imagined the story of the woman in child in a new book called The Strength of Old Shale. Many parts - and characters - in the book are real. She's woven in the stories told to her by Wally Dalziel, a friend she met on motorcycle trips in China, Peru and Turkey. Wally's ancestors worked the goldfields for years, finally buying the farm he continues to run even now. Kirsty's first novel The Strength of Eggshells won the 2020 New Zealand Booklovers Award for best adult fiction.

Fear of confusion sparks name rethink for Manutahi Park
Manutahi is also a tiny town on State Highway 3 in South Taranaki, an hour's drive from Lepperton. Photo: Supplied / LDR Worries about a new Manutahi Park being mistaken for another Manutahi an hour's drive away has New Plymouth's council considering adding the name of a British Military Settler. The park is a planned green space in Lepperton village, about 15km from New Plymouth, on the site of a hall demolished three years ago. New Plymouth District Council asked mana whenua about a name for the park, and Manutahi was suggested by Puketapu hapū. Manutahi remembers the name of the Māori village where Lepperton now stands, as well as nearby Manutahi Pā which was built to defend against British invasion in the Taranaki Wars. The name - literally One Bird - references local bird-hunting forests and is supported by neighbouring Pukerangiora hapū. Manutahi is already widely familiar: it's the name of one of the two country roads intersecting in the village. But a council report said consultation found some locals worried that people would confuse the new park's location with an even smaller hamlet - also called Manutahi - 80 kilometres away between Hāwera and Pātea. "Generally, those who did not support the name felt that [Manutahi Park] did not reflect the Lepperton location and non-locals will not know where it is," staff reported. "The name 'Manutahi Park - Lepperton' is proposed to address this potential confusion." Although, perhaps confusingly, not necessarily as the official name. "The addition of Lepperton ... could either be a formally recognised part of the name or a component that is put in place as required to confirm the location, as opposed to formally recognised as part of the park name." Council policy is that reserves' names reflect history. Taranaki Military Settlers - including their commander Lieutenant Colonel Maxwell Lepper - were volunteers rewarded with Māori land in return for 'policing duties'. Photo: Supplied / Puke Ariki Museum "If there is a strong Māori cultural connection to a reserve, a Māori name should be considered in consultation with mana whenua. "Likewise, a strong European cultural connection to a reserve should result in an appropriate European name. "Where appropriate, both Māori and European names will be used." The report recognised the name might be disputed. "There is a risk that adding the location descriptor of Lepperton to the name could be seen as not needed by hapū and/or some of the community that were supportive of the proposed name." Lieutenant Colonel Maxwell Lepper was a British soldier with the 14th Regiment, redeployed from colonial duties in Ireland to fight Taranaki Māori in 1860. Retiring from the Empire's army, Lepper then commanded the Taranaki Military Settlers - volunteer troops who were rewarded with land taken from Māori in return for 'policing duties'. In 1865 the area was proclaimed confiscated and Manutahi declared a military settlement. Lepper was honoured with the town's name and the family thrived on that confiscated land, with many descendants also recognised on Lepperton's war memorial obelisk and as contributors to Lepperton School. Locals who spoke with Local Democracy Reporting said they were not confused about Manutahi. Taonga pūoro teacher Dave Trinder and Lepperton Primary students like Esme Nesbitt and Maia Lilomaiava had no worries about the name Manutahi. Photo: Photo / Te Korimako o Taranaki Out with the grandkids, Lindy Moratti said she didn't even know where the other Manutahi is. "I cannot see any issue with it, I would not think that would be a problem at all. "To me it's very, very clear and very obvious that it would be here." Speedway driver Sean Price didn't think Manutahi alone would confuse people, but was happy either way. "I'm on the fence really," he said. "Definitely you know where it is, if you say Lepperton - I mean, that confirms it. Lepperton would be bang on." Dave Trinder was delivering taonga pūoro, traditional musical instruments, to Lepperton School for a practice session with students. He deferred to hapū leaders with more knowledge, but neither he nor the kids helping with the taonga had any confusion about Manutahi. The naming decision goes before NPDC's iwi committee Te Huinga Taumatua on Tuesday. LDR is local body journalism co-funded by RNZ and NZ On Air.
