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.

Heading into the end of harvest, growers are reminded that unpicked kiwifruit should be removed from vines by 1 July to help limit wild kiwifruit plants establishing in nearby areas, especially around native bush, or forestry. Fruit left on vines to ripen over the winter months provides a food source for birds (such as the wax-eye/tauhou) that then spread seed into the wild which readily germinates in New Zealand’s environment. Unpicked fruit needs to be dropped to the ground and mulched to prevent this from happening.

We had a busy week at the annual Mystery Creek Fieldays. Thank you for coming by and talking with us, it was great to see such interest in biosecurity – particularly the hornets in resin we had on show. The lunchtime presentations were particularly well attended, and during our talk we discussed ongoing biosecurity protection though our levy proposal – you can read more about that in full detail here. If you’d like more of the pest ID resources we had at the event, please get in touch and we’ll send you copies.

KVH is proposing a small increase to the biosecurity levy to ensure we can continue protecting your orchard and the wider kiwifruit industry from exotic pests and diseases. Levy rates have remained stable for several seasons, while the cost of maintaining strong biosecurity readiness and response has increased, clearly demonstrated with five biosecurity responses in the last two years. The proposed change is about maintaining the level of protection growers rely on today. The proposed biosecurity levy increase is 0.2c, bringing the levy for the 2027-28 financial year to 1c per tray (the Pathway Management Plan levy will remain unchanged at 0.6c per tray). Even with the increase, the impact at an individual grower level is expected to remain small, while collectively it ensures we can respond quickly and effectively to threats. A fruit fly detection in Te Puke could cost up to $700 million in lost market access - making robust biosecurity critical. You’ll find opportunities to ask questions and provide feedback ahead of the AGM on our dedicated web page, with full details of the proposal, including what your levy delivers, why the change is needed, and why continued biosecurity protection is important. KVH will also be out in the regions over the coming weeks to talk through the proposal and answer questions - we encourage you to come along to the presentations, hosted by Chief Executive Leanne Stewart and look forward to seeing you to discuss the proposal. Look out for an email from KVH too, with reminder details of the meeting nearest to you. The feedback you provide will directly shape what is put forward for voting at the AGM and we look forward to discussing it with you.

The Spotted Lanternfly (SLF) is an emerging biosecurity threat to kiwifruit and many other horticultural industries. The pest is hard to control and is a proven invader, capable of flying and hitchhiking on inanimate objects.
SLF attacks over 70 host species, including kiwifruit, grapes, stonefruit and pipfruit. It's preferred host is Tree of Heaven, which is present in New Zealand and considered an invasive weed.
Adults and nymphs feed on young stems and bark tissue with their piercing and sucking mouthparts and excrete large amounts of sticky liquid called honeydew. Extensive feeding results in oozing wounds on trunks, wilting and death of branches. It could severely impact the kiwifruit industry through the sooty mould left on fruit, which renders the fruit unmarketable.
Pest ranking based on the KVH risk matrix
View risk matrixNative to Asia, SLF has invaded North America, where it's numbers have grown rapidly. It is thought to have entered as egg masses on landscaping stone from China and eradication attempts have been unsuccessful. The impacts of SLF have been described as worse than Brown Marmorated Stink Bug (BMSB).
How could it get to New Zealand? The SLF lays its eggs in clusters on smooth surfaces (including vehicles and machinery, shipping containers, and garden furniture) and covers them with a protective layer of wax.
The eggs can then hitchhike on these and other commodities imported into New Zealand. The egg masses are difficult to see and hard to treat with insecticide - see images below of egg masses on kiwifruit and tree bark.
