KVH has produced a new sampling video to help growers and technical staff confidently collect high-quality samples when unusual symptoms are found in the orchard. The video walks viewers through KVH’s simple three-step process and explains what to do before, during and after sampling. It covers the most common sample types, including wood, root, soil, and nursery plant samples, and provides practical tips to avoid contamination and ensure samples are suitable for testing. Correct sampling is an important part of biosecurity and disease investigation. A well-collected sample can help laboratories identify potential pests or diseases more quickly and accurately, supporting faster decision-making and reducing the risk of unnecessary delays. The video also reinforces the importance of contacting KVH first, recording key orchard information, maintaining tool hygiene, and safely packaging and sending samples for testing. Whether it’s a suspected case of Psa or an unusual symptom that could indicate something new, the video provides clear, practical guidance to help ensure the right material reaches the lab the first time. By improving sample quality and consistency, growers can play an important role in supporting early detection and protecting the biosecurity health of the industry. Watch the new video and access supporting sampling resources on the KVH website. If you notice anything unusual, remember to report it to KVH and seek advice before collecting samples.

The brown marmorated stink bug (BMSB) is a serious threat to New Zealand’s crops if it ever establishes here. This project carried out a national baseline survey to identify the stink bug egg parasitoid species already present in New Zealand. The survey gave us a better picture of which species are present and how they might help control BMSB in the future. These insights will support efforts to eradicate or manage BMSB if it ever arrives in New Zealand. This work was funded through Sustainable Food and Fibre Futures (SFFF). You can view the full report here.

KVH was proud to be part of both the Bay of Plenty and Nelson Young Grower of the Year competitions held recently, helping put competitors’ biosecurity knowledge and practical skills to the test. In Nelson, we partnered with Farmlands to deliver the biosecurity module – thank you to the Farmlands team for their support. Designed to reflect real orchard situations, the modules challenged contestants to think on their feet and demonstrate how they would respond to potential biosecurity threats. The high standard of competition was encouraging, with participants showing strong practical knowledge and a clear understanding of the role biosecurity plays in protecting not only the kiwifruit industry, but New Zealand’s wider horticultural sector. Congratulations to the Bay of Plenty biosecurity module winner, Danyon Robertson, and to Nelson module winner, Samual Lee. Congratulations also to William Kenna, Orchard and Innovation Lead at KWKiwi, who was named the Bay of Plenty Young Grower of the Year, and Amelia Marsden, Nursery Manager at Thomas Brothers Orchard in Riwaka, who claimed the Nelson title for the second consecutive year. Both will now compete against six other regional champions at the National Young Grower of the Year competition in late August, where KVH will once again be putting finalists through their paces with a biosecurity challenge. It's always encouraging to see the commitment and biosecurity awareness shown by the next generation of horticultural leaders. Events like these play an important role in developing the knowledge and skills needed to help safeguard our industries into the future. See images from the events here.

New Zealand is well prepared to respond if bird flu reaches our shores, but it is important that everyone takes steps now to be ready. One of the most noticeable signs of bird flu is the swift death of multiple birds in a group. If you see three or more sick or dead wild birds in a group, report it immediately to the Biosecurity New Zealand hotline on 0800 80 99 66. A specialist biosecurity investigator will assess the information and advise you further. Don’t handle or move the birds. Provide the 0800 number with as much information as you can, including precise location information; photographs and videos of sick and dead birds; how many are sick or freshly dead; and the total number of birds present. If you own birds – including chickens, ducks, show birds or pets – you can take steps now to protect them with good biosecurity and hygiene practices. Full advice for bird owners is available on the dedicated bird flu website here.

Four new research projects have been launched to support efforts to eradicate the yellow-legged hornet from New Zealand. The work will be led by scientists at the Bioeconomy Science Institute and includes modelling to identify areas in Auckland most at risk of ongoing hornet presence, helping focus surveillance and response activities. The research comes as the response continues to make encouraging progress, with 77 queens and 132 nests removed since the pest was first detected on Auckland’s North Shore last year and no confirmed sightings since early April. However, ongoing surveillance remains critical to ensure any surviving queens are detected. Other projects will assess the potential impacts of the hornet beyond urban areas, improve awareness among Māori communities, and develop a readiness package for the honey and pollination sectors should long-term management ever be required. For kiwifruit growers, the message remains the same: stay alert and continue reporting any suspected yellow-legged hornets or nests. Every report helps protect New Zealand’s pollinators, and horticulture industries. See more about the Biosecurity New Zealand-led response and KVH’s ongoing input on behalf of the kiwifruit industry.

Thank you to everyone who has joined us at the grower meetings held so far in Pukekohe, Waikato, and Te Puke to discuss KVH’s proposed biosecurity levy increase. We’ve appreciated the thoughtful questions, feedback and discussion shared to date. The proposal is for a 0.2c increase to the biosecurity levy, taking it from 0.8c to 1c per tray from the 2027/28 financial year. The Pathway Management Plan levy will remain unchanged at 0.6c per tray. Biosecurity risk continues to grow and at the same time, the cost of maintaining readiness and responding effectively has increased. The industry’s obligations under the Government Industry Agreement for Biosecurity (GIA) have been clearly demonstrated with five biosecurity responses in the last two years. Levy rates, however, have remained steady for several seasons and with recent response costs, that means the real level of protection through sufficient reserves is slowly eroding. To learn more, some of the resources we have available include a podcast with KVH Chief Executive Leanne Stewart and a one page fact sheet. There are plenty of opportunities to provide feedback and have your questions answered at further upcoming regional meetings – you can see the full schedule here. We encourage all growers to attend a session, hear directly from KVH, and join the conversation about what this proposal means for ongoing biosecurity protection of our industry. Your feedback is an important part of the consultation process. We encourage you to review the proposal information, ask questions, and share your views that will directly shape what is put forward for voting at the AGM.

Fruit flies are the kiwifruit industry's most unwanted biosecurity threat. Any incursion can severely impact where we sell our fruit. The high risk period for fruit flies is September to June.
The Queensland Fruit Fly (QFF), native to Australia (our closest neighbour), is considered to be the greatest threat and has the most market impacts.
The financial impact of a fruit fly incursion in Te Puke to New Zealand’s kiwifruit industry is estimated to be between $200 million and $695 million. A Kiwifruit Journal article summarises the financial impacts of different incursion scenarios based on previous fruit fly incursions in New Zealand and overseas and economic modelling by Underwood (2023).
Pest ranking based on the KVH risk matrix
View risk matrixKVH has developed a guide for growers that details the likely sequence of events if a fruit fly response was to occur in a kiwifruit growing region.
Plant & Food Research have been granted permission to import sterile QFF into a New Zealand containment facility to develop new attractants for female and male flies.
This long-term project will determine what the flies can smell and whether the odours can be used to improve the sensitivity of traps or increase the numbers of flies lured in. Three approaches are being used; odours based on host fruit, sex pheromones and bacteria.
This research is part of a larger collaborative approach with Australian organisations to manage and eradicate QFF populations.
Supporting this is a Sterile Insect Technique (SIT) facility that can produce 50 million sterile QFF per week as an eradication tool for release in Australia or New Zealand should an established population ever become large enough for this to be required. Read more about the project here.
KVH supports these research activities as an integral component of our readiness activities for the industry’s most unwanted biosecurity threat.
KVH investigates reports of unusual symptoms to identify and manage any biosecurity risks.
