Controls lifted at Otago poultry farm after bird flu virus eradicated
The highly pathogenic bird flu strain H7N6 was detected in poultry at Mainland Poultry's Hillgrove Farm in early December, prompting restrictions to be put in place and the culling of tens of thousands of chickens in the weeks following.
Minsitry for Primary Industries (MPI) moved swiftly to implement strict movement controls on the property to prevent goods or anything else that might be carrying the virus leaving the property.
Chickens on the farm were humanely euthanised and disposed of in a secure landfill, along with eggs, litter and manure from the farm. This was followed by an extensive cleaning and disinfection process.

In an update today, Ministry for Primary Industries (MPI) chief veterinary officer Mary Van Andel said more than 5600 tests have been carried out on samples from poultry and wild birds, including from 36 flocks across 5 farms linked to Mainland's Hillgrove property.
"HPAI was not found anywhere other than Hillgrove, giving confidence that the disease had been contained and stamped out," she said.
"The processes we have followed – depopulation and disposal, decontamination of the site and extensive surveillance – give us confidence that the virus has been eradicated."
"While there is still work to be done, the lifting of movement controls is a significant milestone in the response and means that Mainland Poultry can begin the process of returning to business."
Van Andel thanked Mainland Poultry for notifying MPI promptly when the disease was suspected and working to stamp it out successfully.
"Good progress is being made to restore trade, with around $300 million of trade in poultry products recovered to date.'
Biosecurity Minister Andrew Hoggard praised the collaboration among industries and "rapid action" taken to contain and stamp out the disease.
"Rapid action on behalf of the farmer and MPI to stand up a response and restrict movements paid off. Tracing did not detect any HPAI-infected chickens beyond the farm where the disease originated.
He said this has been "important work" as New Zealand's robust biosecurity system and the relative freedom from pests and disease plays a role in farmers' competitive advantage.
"This was the first detection of HPAI in New Zealand and it tested some of the plans that are being developed for the arrival of HPAI H5N1.
"It certainly provides a timely reminder that all New Zealanders have a role to play in being prepared and that is through strong biosecurity as an essential first line of defence."

Dengue fever outbreak: New Zealand steps in to help as Samoa grapples with deaths
'We are closely monitoring the dengue situation across the Pacific and stand ready to consider other requests for support.' Young brothers among death toll Other countries that have declared a dengue fever outbreak in the past few months are Tonga, the Cook Islands and Fiji. Dengue fever, also known as break-bone fever, is a viral infection that spreads from mosquitoes to people and causes symptoms that include sudden high fever, intensely sore joints and muscles, pain behind the eyes and a rash. Fumigation efforts have been under way in Samoa this week as it deals with a dengue fever outbreak. Photo / Govt of Samoa The official death toll in Samoa stands at four, with a fifth death – a 2-year-old boy who died over the weekend – being deemed as a probable dengue-related death at this stage. The boy is the youngest person to have lost their life over the past few months. His death came just a few days after his older brother, 9, succumbed to the same disease last week. Their deaths follow that of a 5-year-old girl, whose death was declared by local health authorities on Monday last week. The first death reported in Samoa was 12-year-old Misiafa Lene, who contracted the disease in April and died a week later, despite his family's efforts to medically evacuate him to Starship children's hospital in Auckland. Speaking to the Herald at the time, his parents described the nightmare they were living. 'The pain is beyond anything. We don't want another family to go through what we are going through.' As of Sunday, a total of 5670 clinically diagnosed cases of dengue have been recorded since January. Of those, just over 2600 are laboratory-confirmed cases, according to the Samoan Government's latest figures. Last week, 1446 new clinically diagnosed cases were reported across Upolu and Savai'i – Samoa's two main islands – and included 342 new lab-confirmed cases. Samoa has shut down all schools as fumigation programmes start in the country's fight against dengue fever. Photo / Govt of Samoa Samoa's main hospital, near Apia, has had to make changes to its day-to-day operations to keep up with the surging cases of dengue fever among the community. Those changes include revised operating hours for general outpatients, with only patients with dengue-like symptoms being attended to from 6pm until morning. People with mild dengue-like symptoms, including fever, headache and joint pain without warning signs, are encouraged to stay home and manage symptoms with adequate hydration and paracetamol. Travellers: Pack insect repellent MFAT said it had not been approached for assistance by any New Zealanders in Samoa. However, people due to travel to Samoa, particularly those with children, are being urged to heed safety messages. People are advised to pack insect repellent, protective clothing and use mosquito nets when sleeping – especially for children, the elderly and pregnant women. An influx of Samoan community members from overseas, particularly from New Zealand and Australia, is set to head to Samoa over the next few weeks before the country's general elections this month. Although the majority of the dengue fever cases and all of the dengue-related deaths have been children, elderly members of the public are also vulnerable to the mosquito-borne viral illness. 'Travellers to Samoa should always take precautions to protect themselves from mosquito bites,' MFAT authorities say. 'We encourage all travellers to follow the dengue fever prevention advice on our SafeTravel website and further information.' Travellers to Samoa are also being encouraged to take out comprehensive travel insurance that includes medical evacuation in case of an emergency. People should also register their details on MFAT's SafeTravel site. Vaimoana Mase is the Pasifika editor for the Herald's Talanoa section, sharing stories from the Pacific community.

MNZM And NZ Innovator Of The Year Dr John Hyndman Stands For ACT Local
Press Release – ACT New Zealand John brings decades of medical and governance experience to the table. He served for many years at Wairau Hospital and was instrumental in establishing the Churchill private hospital and Hospice Marlborough. ACT Local has selected Dr John Hyndman, a retired Specialist Anaesthetist, award-winning medical innovator, and recipient of the New Zealand Order of Merit – as its candidate for the Blenheim Ward in the upcoming Marlborough District Council election. Dr Hyndman was recognised in 2016 as NZ Innovator of the Year and appointed a Member of the New Zealand Order of Merit for developing a low-cost anaesthesia machine used in developing countries. John brings decades of medical and governance experience to the table. He served for many years at Wairau Hospital and was instrumental in establishing the Churchill private hospital and Hospice Marlborough. He also chaired the Marlborough Health Trust and now co-directs a medical immigration business helping bring overseas doctors and nurses to New Zealand. Dr Hyndman recently moved to his new home in Picton and is standing to bring a calm, constructive voice to the council chamber – one that focuses on oversight, sound infrastructure, and ratepayer value. 'I'm standing because I believe ratepayers deserve better. In tough times, every dollar counts. I want to be a positive influence around the council table – not to throw stones, but to make sure promises are kept. That means delivering on infrastructure, keeping rates down, and making sure council spending stays grounded in reality.' – Dr John Hyndman Dr Hyndman says ratepayers deserve more than good intentions, they need councils that stick to the basics, keep costs under control, and stop wasting money. 'After a career in medicine and running businesses, I know how important it is to be organised, take responsibility, and focus on outcomes. That's how councils should operate too. I want to bring common sense and steady oversight to the Marlborough District Council.' – Dr John Hyndman Earlier this year, ACT New Zealand announced it would be standing Common Sense Candidates for local government for the first time — after hearing from New Zealanders across the country who are sick of rising rates, ballooning budgets, and councils that ignore the basics while chasing ideological vanity projects. When you vote ACT Local, you know what you're getting: Fixing the basics Lower Rates Cutting the waste Stopping race-based politics Restoring accountability Ending the war on cars ACT Local Government spokesperson Cameron Luxton says: ' ACT Local candidates are community-minded Kiwis who've had enough of wasteful councils treating ratepayers like ATMs. It's time to take control on behalf of ratepayers — to restore accountability and deliver real value for money. ACT Local is about getting the basics right: maintaining roads, keeping streets clean, and respecting the people who pay the bills. Our candidates won't divide people by race or get distracted by climate vanity projects. They're here to serve, not lecture.' – Cameron Luxton

Seafood NZ Prepares For 'Thoughtful' Conference – Seafood's Science, Storytelling And Health Benefits All On The Table
Providing 'Food for Thought', as well as literally providing the best possible food for New Zealanders, are themes of the Seafood New Zealand 2025 Conference, kicking off on Wednesday 6 August in Nelson. The group representing New Zealand's commercial fishing sector is hosting around 250 industry leaders at the Conference, including scientists, operations experts and hands-on fishers. This year's theme is "Seafood for Thought' – an obvious play on the phrase "food for thought" – which is all about encouraging fresh thinking, new conversations, and smarter ways of working together. Conference delegates will hear from a range of speakers including Shane Jones, the Minister for Oceans and Fisheries, who will open the 2025 Conference. Seafood New Zealand CEO, Lisa Futschek says there are three main strands to the Seafood for Thought theme. 'We're focused on the science that backs up our industry. We'll be asking how we can develop fishing technology that reduces our impacts and also allows us to fish in a smart and efficient way. 'Another area of focus is telling our story. New Zealand commercial fishing is lauded overseas - for example, a recent FAO report from the UN put us second in the world for sustainable management - and yet locally we are not so well recognised. How do we get better at sharing our stories with New Zealanders? 'And then we will look at the latest science around the health benefits of seafood consumption. We are fortunate enough to have two distinguished Australian scientists joining us in Nelson, who have just completed a review of the latest science around this very topic. We're looking forward to them revealing what their review of 281 of the newest and highest quality scientific papers says about the nutrition that seafood can provide and the impact that can have on human health.' Other topics on the table, providing Seafood for Thought are: • How the sector can sustainably grow its export value. Seafood is already worth around $2.2 billion a year to the New Zealand economy, so how do we increase this in a way that is sustainable for our ecosystems • What we can do to manage the trade-related challenges we face in today's fast changing geopolitical environment The Conference will also hear about safety at sea and on land, careers in seafood and how skippers can contribute to the science needed to manage our fisheries with greater certainty. The 2025 Seafood New Zealand Conference runs for two days – August 6 and 7. Fast Facts – Key Data about New Zealand Commercial Fishing • New Zealand's commercial wild capture fisheries are worth $1.6 billion in export revenue • Our seafood sector produces $2.2 billion in export revenue in total (including aquaculture) • 16,500 Kiwis are employed either directly or indirectly in seafood • Fisheries management is complex – there are 642 fish stocks under management • New Zealand fish stocks are in good shape. 97.3% of total commercial landings by weight are from stocks that are considered sustainable (see MPI data).
