Earlier this month, KVH attended a workshop hosted by researchers from the Bioeconomy Science Institute (BSI) to hear findings from the first year of a Better Border Biosecurity (B3) social science research project focused on biosecurity engagement. The three-year project is exploring how industries and communities understand, engage with, and support biosecurity practices. Its aim is to help strengthen social licence and encourage practical biosecurity action across New Zealand’s primary sectors and communities. Three case studies have been completed during the project’s first year, focusing on on-orchard biosecurity practices within the kiwifruit industry, Lepidoptera readiness planning, and Māori biosecurity engagement within pollination services. The workshop shared valuable insights into how biosecurity is viewed and applied across different settings, and highlighted the importance of practical, people-focused approaches to improving engagement. The next phase of the project will involve researchers and biosecurity partners working together to co-design practical tools and approaches to strengthen biosecurity participation. Over the coming months, findings from the case studies will be shared with interview participants and then more widely released. KVH thanks everyone who contributed their time, experience and insights to the project. The open and constructive discussions provided valuable perspectives that will help shape future biosecurity engagement initiatives across the sector.

Good news for the kiwifruit industry – the brown marmorated stink bug (BMSB) investigation in Orākei, Auckland has concluded with no further detections. The eighth and final scheduled trap check was completed at the end of April, confirming that no additional BMSB were present after the single find in early February. All surveillance and investigation activities linked to this detection are now finished. Biosecurity New Zealand has thanked KVH for supporting the deployment and management of additional BMSB traps, which strengthens the national surveillance programme’s effort. The investigation also highlighted the value of strong partnerships between industry, on behalf of growers, and Biosecurity New Zealand in protecting New Zealand’s biosecurity system. This is a positive outcome for our industry and all kiwifruit growers. Read more about KVH’s BMSB industry surveillance activities here.

Published by New Zealand Geographic, this comprehensive article follows the real‑life biosecurity effort in Auckland to find and eliminate the Yellow‑legged hornet before it can gain any foothold in New Zealand. The article highlights how this aggressive invasive insect poses a serious risk to pollinators and horticulture and shows the scale and complexity of the response operation - from public sightings and field surveillance to specialist tracking and nest destruction. It underlines the critical role of early detection and reporting in protecting New Zealand’s primary industries – including kiwifruit growers - demonstrating how community vigilance and rapid response can make all the difference between eradication and long‑term impact.

KVH joined the action at the recent AgriFutures Clash of the Colleges competition held for the first time in the Bay of Plenty and hosted at Kenna’s Kiwifruit Orchard in Katikati. Thirty-four teams of four students, representing eight secondary schools, competed across 17 agriculture and horticulture modules designed to showcase the practical, fast-paced nature of New Zealand’s primary industries. As part of the KVH activity, teams were challenged to identify pest images retrieved from surveillance traps and determine which pests were already present in New Zealand and which represented potential biosecurity threats that should be reported to Biosecurity New Zealand. Amongst the common New Zealand huhu beetles, butterflies and shield bugs, many teams quickly identified and reported the brown marmorated stink bug (BMSB) and fruit piercing moth, two of the “most unwanted” featured on KVH’s pest ID cards, a well referenced resource at the event. AgriFutures Clash of the Colleges was first launched in 2019 and was brought to the Bay of Plenty through the support and encouragement of local organisers who are already planning for an even bigger competition next year.

The response to the Yellow‑legged hornet in Auckland is tracking well, with no hornets or nests detected for more than six weeks, which is considered a strong signal that eradication is achievable. Detection activity has remained confined to a small area on Auckland’s North Shore, and the lack of recent finds, despite intensive trapping and searching, has increased confidence the incursion is being successfully contained. As outlined by Biosecurity Minister Andrew Hoggard yesterday, the response is now shifting into a new phase as winter approaches. Field operations will scale back from intensive searching to ongoing trapping and monitoring, while teams prepare for the risk of any surviving queens emerging in spring. The Minister emphasised that eradication will take time, requiring several years of surveillance with no detections, and urged the public to remain vigilant, continuing to report any sightings and take care not to inadvertently spread overwintering queens. More information is available on the KVH Yellow-legged hornet response page.

KVH recently attended the 2026 Plant Biosecurity Research Symposium in Melbourne, which brought together researchers, industry, and government partners from across Australia and New Zealand. The event coincided with the United Nations International Day of Plant Health and focused on the theme Plant Biosecurity for Food Security and showcased the latest research and thinking across key areas, including early warning and risk, diagnostics and surveillance, resilient crop protection systems, and readiness and recovery. Research aimed at better understanding emerging risks was highlighted, including the impacts of climate change, as well as the development of tools to support industry-led risk assessment. There was a strong focus on improving diagnostic capability, with new tools in development to enable faster, more effective identification of unwanted organisms at the border and post-border, supporting more rapid response times. Importantly, the symposium reinforced the value of connections across the Tasman. Building relationships with Australian counterparts is highly beneficial, as both countries face many of the same biosecurity threats, often with pests and diseases establishing in Australia first. These connections support shared learning, early awareness, and stronger collaboration to protect New Zealand’s kiwifruit industry.

Winter is a key time for replanting or establishing new kiwifruit blocks. Whether you're replacing old vines or developing a new area, it's vital to stay on top of biosecurity requirements - especially when moving plants between properties. Following biosecurity requirements reduces the risk of spreading pests and diseases like Psa and helps ensure a rapid, effective response if a new organism is detected. Growers must only source kiwifruit plants from nurseries that meet the National Kiwifruit Pathway Management Plan requirements. This means certification through one of the following: KVH’s Kiwifruit Plant Certification Scheme (KPCS) Plant Pass, a broad nursery certification programme for all plant types You’ll find a list of certified nurseries on the KVH website. Two levels of certification are available: Full Certification: Plants are free from Psa and other target organisms. These nurseries operate in Psa-free environments and provide plants that have tested Psa Not Detected. Restricted Certification: Plants may carry the common New Zealand strain of Psa (Psa-V) but are tested to be free from more harmful, resistant, or offshore strains. Growers can produce their own plants on the property they’ll be used on, without certification. Additionally, up to 1,000 plants per year may be moved between properties under the same ownership (KPINs). While certification isn't needed in these cases, accurate traceability records must be kept. Important reminders: Do not move any plants showing disease symptoms. Both the supplying nursery and the receiving property must maintain traceability records in case symptoms appear later and tracing is required. For further guidance or to view certified nursery lists, visit the KVH nursery web page or contact us directly.

Earlier this year Plant Diagnostics Ltd hosted an Australian nematologist for a four-day training programme focused on nematode identification and diagnostics. KVH worked alongside other agriculture and horticulture sectors to support the training by providing samples from kiwifruit orchards with a history of nematode issues, along with representative orchard block samples where no known issues were present. Samples were also contributed from a range of other production systems including citrus, vineyards, berryfruit, potato, spinach and onion crops. The training provided valuable exposure to a wide range of plant-parasitic nematodes and helped strengthen diagnostic capability across New Zealand’s plant health network. Plant-parasitic nematodes are an often overlooked but important group of organisms that can impact root health, plant vigour, and crop performance. Having skilled diagnosticians and diagnostic capability across industries plays an important role in supporting early identification, investigation and management of emerging plant health issues. KVH thanks industry partners who supported the submission of samples and contributed to building this important capability.

Assess your orchard risk and develop a plan
Individual orchards have different biosecurity risk profiles. Variety, region, orchard environment and management practices all contribute to the orchard risk profile.
Use the easy 5-step on-orchard biosecurity plan template to identify risks, and how to address them. Click here to read more and complete your plan online, or download a copy of the booklet.
Orchards also have varying Psa risk profiles. For example, Psa severity will be worse in seasons/regions when winter is colder and early spring is wetter. This risk should be considered when formulating your Psa management plans. Information and best practice advice is co-ordinated by Zespri and available on the Zespri Canopy here.
Weather & Disease Portal
The Zespri Weather & Disease Portal is an online, weather-based decision support tool to assist growers with orchard management in a Psa environment. Weather station data and weather forecast information is combined to provide customised access to unique weather information, disease information and interpretations.
Within the portal you can choose to receive a daily email report for weather and risk information. These reports are tailored for kiwifruit growers and come in a convenient PDF format that you can forward to your team members, view on your phone, or print. You can choose what time of the day the reports are sent, and for which locations.
Traceability with Onside
Through Onside, you can quickly and easily record all mandatory information of plant material movement to satisfy Pathway Management Plan and GAP requirements. All users of the Onside app can use this free functionality - all you need to do is:
Growers can still keep physical records of plant material movements, but this free digital option has been designed to simplify the process of providing plant movement records as part of a GAP audit.
Get signage
KVH-produced corflute biosecurity signage is available for orchard entry points free of charge. These signs are to raise biosecurity awareness for people entering an orchard or nursery, and to help you set agreed expectations for best biosecurity practice.
