As pollination season gets underway, KVH reminds growers and beekeepers that any movement of beehives across Cook Strait for use in kiwifruit orchards or nurseries requires prior KVH authorisation. The Cook Strait remains an important biosecurity barrier between the North and South Islands. Because the South Island remains free of Psa-V, controls are in place to help prevent the spread of the pathogen through pollination-related activities, including the movement of beehives. Before moving hives across Cook Strait: Contact KVH at least seven days before the proposed movement to obtain authorisation. Where hives have been used on North Island kiwifruit orchards, a minimum 10-day stand-down period is recommended at a North Island location outside kiwifruit growing regions before moving south. Ensure hives, pallets, machinery, vehicles, tools, equipment and footwear are free of kiwifruit plant material and debris and sanitised using a KVH-approved sanitiser. Contractors without a Zespri CAV must complete a Non-CAV Contractor Biosecurity Plan before entering orchards. Growers also have a role to play by confirming where pollination hives are coming from, ensuring biosecurity requirements have been met, and reporting any unusual symptoms in their orchards to KVH immediately. These requirements are part of the Biosecurity (National Kiwifruit Pathway Management Plan) Order 2022, with compliance helping protect the South Island and the wider industry from Psa-V. Non-compliance with plan rules may constitute an offence under the Biosecurity Act 1993.

Pūkeko can sometimes become a nuisance in kiwifruit orchards, particularly when bird numbers are high. Growers have reported damage from birds entering the canopy and snipping off new shoots in spring, feeding on ripening fruit before harvest, or pulling out and damaging young plants and seedlings. Before taking any action, it's important to confirm that pūkeko are causing the damage. Pūkeko are partially protected and are valued by many New Zealanders. Control can also be challenging where orchards are located near wetlands, damp pasture, waterways, or urban areas that provide ideal habitat. If pūkeko are causing ongoing problems in your orchard, consider the following management options: Use bird-scaring techniques such as occasional bird-scare blasts, pyrotechnics, or other approved deterrents to encourage birds to move away from the orchard. Consider bird repellent products where appropriate. Always follow label instructions and any restrictions relating to timing and application rates. Population control may be possible during the game bird hunting season, provided all Fish & Game regulations and firearm safety requirements are followed. Outside the hunting season, a permit from Fish & Game is required before any control activities can occur. Netting may provide a longer-term solution where pūkeko pressure is persistent and causing significant crop losses. Growers should ensure any management actions comply with relevant wildlife, firearms, and health and safety regulations.

KVH recently attended the latest Programme Advisory Committee (PAC) meeting for the Protecting Aotearoa from wind-dispersed pests research programme, led by the Scion group at the Bioeconomy Science Institute (BSI). The programme aims to strengthen New Zealand's biosecurity system by developing tools to predict when insects and plant pathogens may arrive and spread via wind-assisted pathways. KVH is one of several industry organisations represented on the PAC, alongside members from government, research organisations, regional councils, and other primary sector groups. The PAC helps ensure the knowledge generated by the programme is translated into practical outcomes and provides guidance on research priorities, communication pathways, and end-user needs. At the recent meeting, researchers shared progress on understanding how insects and pathogens survive long-distance atmospheric transport, improving models that predict pest movement, and analysing intercepted insects to better understand where they originate. The overall aim of the programme is to develop the Aerobiological Surveillance and Prediction System (ASaP), an early warning tool designed to identify periods and locations of increased risk for wind-borne pest arrivals, helping improve surveillance of this pathway. For the kiwifruit industry, this research has the potential to improve preparedness and support more targeted surveillance for offshore pest and disease threats. As climate patterns continue to change, understanding how wind-assisted pathways influence pest movements will become increasingly important for protecting New Zealand's horticultural industries and natural environments.

Trunk cankers and exudates, uneven budbreak, and leader or cane dieback are some of the reports recently brought to KVH's attention through the unusual symptoms process. Orchard visits have helped identify where trunk disease is occurring and how extensive it is. Diagnostic sampling has also helped confirm the fungal pathogens associated with some of these symptoms, supporting growers with management decisions. Not all unusual symptoms are caused solely by pathogens. Patchy or poor budbreak can also be linked to poor root health caused by waterlogging, soil compaction or insufficient water during very dry periods. Other factors such as planting too deeply, placing compost too close to vine trunks, and allowing grass and weeds to grow around trunks can also contribute to poor vine health and vine failure. Research which has identified several fungal pathogens associated with different trunk disease symptoms is available on the KVH website and Zespri Canopy. Unusual vine symptoms can be reported to KVH online or by phoning 0800 665 825. See images from recent reports

From now through to autumn, New Zealand enters the highest-risk period for two of the kiwifruit industry’s most unwanted biosecurity threats, exotic fruit flies and brown marmorated stink bug (BMSB). The high-risk season typically runs from September through to May, when warmer temperatures, increased international trade pathways, and higher numbers of international visitors heightens the likelihood of these pests arriving in New Zealand. Exotic fruit flies remain the kiwifruit industry’s number one biosecurity threat due to the severe market access impacts they could cause. BMSB is one of the highest-priority pests for kiwifruit, capable of damaging fruit and affecting production if it were to establish here. The 2026/27 season marks 10 years of New Zealand’s BMSB programme, highlighting a decade of investment in keeping this significant pest out of the country. Key activities planned for this season include: Increased scrutiny of Italian ceramic and tile imports following detections associated with these products in Australia. More verification inspections of full containers that have undergone offshore cleaning or other approved treatment systems. Uzbekistan is expected to be reclassified as a full BMSB-risk country, with containers arriving from the country continuing to undergo verification checks. Continued awareness activities targeting international air passengers. Officers will focus on travellers arriving from the United States, Canada, and Japan, providing information on BMSB and what to do if a suspect bug is found in luggage or personal belongings. New Zealand remains free of both pests, but ongoing vigilance is critical. Keep an eye out for anything unusual on-orchard, check pest ID resources with staff and contractors, and report any suspect insects, damage, or symptoms immediately. Early detection gives us the best chance of stopping a pest before it can establish. If something doesn’t look right, don’t wait. Contact KVH or the Biosecurity New Zealand hotline 24/7 on 0800 665 825. Order pest ID resources

An upcoming webinar may be of interest to growers keen to learn more about the human factors that influence biosecurity action and the role orchard biosecurity plans play in strengthening New Zealand's biosecurity system. A new Better Border Biosecurity (B3) research project is exploring how to improve biosecurity engagement across New Zealand by addressing challenges such as complacency and strengthening social licence for biosecurity initiatives. One of the project's first-year case studies focuses on the implementation of biosecurity plans on kiwifruit orchards, examining how growers understand and apply biosecurity practices in their day-to-day operations. The findings give insights into what growers are doing well and where challenges remain; how biosecurity behaviours are influenced by practical orchard realities; and opportunities to improve preparedness for future pest and disease incursions. The webinar will also share insights from case studies on community readiness planning and Māori engagement in pollination services, providing a broader view of how biosecurity is supported across sectors and communities. Date: Thursday, 1 October 2026 Time: 11:00 am - 12:00 pm Where: Online (Microsoft Teams) RSVP: Register here

The response to eradicate the yellow-legged hornet in Auckland has entered a crucial stage, with warmer spring weather increasing the risk of any surviving queens emerging from winter. Since the response began, 77 queens and 133 nests have been destroyed, and no hornets have been detected since April. Biosecurity New Zealand is now increasing surveillance, trapping, and monitoring efforts across Auckland during this high-risk period. While progress is encouraging, we continue to urge growers to remain vigilant and report any suspected yellow-legged hornets or nests immediately. More than 18,000 public reports have contributed to the response so far. The yellow-legged hornet is a significant threat to honeybees and pollinators. KVH continues to work closely with Biosecurity New Zealand and other industry groups to minimise risk to New Zealand growers and exporters and ensure all response activities are in the interests of kiwifruit growers being able to maintain access to sufficient levels of pollination services in future seasons. If eradication is successful and no further hornets are found during ongoing surveillance, New Zealand will be able to declare the pest eradicated in line with international standards. Suspected sightings can be reported to Biosecurity New Zealand online or by calling the hotline on 0800 80 99 66. Regular updates and resources are available on the KVH website, including: How to ID a hornet: poster How to look for hornets and their nests on your property: video How to make a homemade hornet trap: fact sheet

New Zealand’s border biosecurity systems continue to deliver strong protection against unwanted pests and diseases, with the latest monitoring results showing high levels of compliance across both international air passengers and mail. Latest figures from Biosecurity New Zealand show during 2025/26, passenger compliance reached 98.92%, exceeding the target of 98.5%. More than 11,000 passengers and crew were surveyed at Auckland, Wellington, Christchurch and Queenstown airports, with only 119 people found carrying undeclared biosecurity risk goods. International mail also performed well, achieving a 99.73% compliance rate, comfortably above the 99% target. Of the 3,628 mail items sampled after screening, only 12 contained non-compliant risk goods, including seeds, plant, animal, and bee products. With more than 11.7 million international mail items arriving in New Zealand during the year, the latest results provide reassurance that our border biosecurity controls remain robust and effective in reducing the risk of pests and diseases entering the country.

Read more about Border biosecurity controls perform stronglyIn October 2020, KVH and the Bay of Plenty Regional Council (BOPRC) signed an agreement to continue to work together to manage this pest plant over the next 10 years. Under the new agreement, KVH will manage the administration involved in the running of the programme while also contributing $150,000 annually towards control costs and surveillance costs. BOPRC will contribute $100,000 per annum and support KVH in gathering landowner contributions.
KVH has also partnered with Zespri and the Kiwifruit Breeding Centre. Through their significant contributions, the programme has been able to expand and control wild kiwifruit infestations previously left unchecked.
If you know the location of any unrecorded wild kiwifruit infestations, contact your local regional council or unitary authority with details so the infestation can be assessed and programmed for control.
Why control the wild population? The reason wild kiwifruit vines are a biosecurity risk to New Zealand’s kiwifruit industry is that they act as a vector for Psa and other kiwifruit pests and diseases. The wild population can act as a reservoir for biosecurity threats, undermining eradication, and control efforts on commercially productive vines.
They are also a threat to our environment. Wild kiwifruit vines are vigorous climbers, and if left uncontrolled, it can form dense heavy blankets of vines that strangle trees, causing them to die or collapse. Vines can also smother forestry plantations and New Zealand’s native bush.
GROWERS
Remove unpicked fruit from vines and mulch as soon as possible. This prevents mass feeding by birds and allows the fruit to compost as quickly as possible.
POST-HARVEST OPERATORS
Cover bins of reject fruit to prevent birds feeding on ripening fruit.
FARMERS
Cover stockpiles of fruit with shade cloth, windbreak netting or something similar to prevent birds from getting to any fruit. Feed out only what will be eaten by stock at one time to prevent birds from eating leftovers.
MEMBERS OF THE PUBLIC
Be very careful with the disposal of kiwifruit, particularly while out in the bush.
KILL WILD KIWIFRUIT PLANTS
Cut vines at ground level. Apply Vigilant Gel® herbicide to the top and sides of the cut stump or any exposed roots. Ring-bark stumps or large roots with a machete or pruning saw to assist absorption of the herbicide gel. Carefully trace all vine stems to find where they may have taken root. Cut any rooted stems at ground level and apply Vigilant Gel®. Never apply Vigilant Gel to stumps within a kiwifruit orchard. For controlling kiwifruit stumps within an orchard, please refer here.
KVH investigates reports of unusual symptoms to identify and manage any biosecurity risks.
