Unusual symptoms

When information about unusual symptoms is reported to KVH (by growers, contractors, pack-house staff and others visiting orchards) it is then looked into to be sure that any biosecurity risk is identified, managed and the growers involved are well supported if any further action needs to be taken.

KVH prepares full reports on every investigation which you can read about by clicking on the link below. This information is provided to help growers, and others in the kiwifruit industry, identify similar symptoms they may be seeing on their own properties and to increase general awareness of how growers need to be reporting unusual symptoms that they may be seeing.

Reporting the unusual is a good thing – it shows that as an industry we are all on the lookout and aware of the need to report potential biosecurity threats that could be significant risks to the industry.

Growers, contractors, and anyone else on-orchard are the best people to spot anything unusual early on. If it's a pest or bug you're reporting, catch it if you can and take a photo. If it's a disease symptom on a plant, tree, or vine, take some clear photos but try not to touch it. Remember, the sooner a report is made and looked into, the more we can do to slow the spread and limit impacts.

Stay vigilant, be on the lookout, and report anything you notice to KVH online; on 0800 665 825; or call the Biosecurity New Zealand pest and disease hotline 24/7 on 0800 80 99 66.

You can also make reports online by submitting images to Biosecurity New Zealand here or by using the free Find-A-Pest app here to help ID pests of concern.

what happens next

The potential benefit to our industry of making a report cannot be overestimated, and the earlier something is reported the greater chance we have of eradicating it.

Although generic and only slightly different for each report and case, there is a process for what happens next that you can be assured of, and that will always include ongoing support and contact with KVH.

After reporting


Actions I can take to ensure smooth-running

Identification, assessment and response

The suspicious find is identified. In most instances it is found to not be of concern with no further action required, or not new to New Zealand and managed on-orchard.

If the organism is found to be new to New Zealand, Biosecurity New Zealand will undertake an investigation to determine risk of the organism and feasibility of undertaking action. Biosecurity New Zealand will contain the pest/pathogen to understand more about it and the impact it may have.

Biosecurity New Zealand, KVH and any other affected groups then work together to decide whether to formally respond and if so, set goals such as eradication or containment. Sometimes a response then moves into long-term management (as is the case with Psa currently).

Timeframes from notification to a response decision vary. For pests with serious impacts that we know a lot about (like fruit fly) it can be immediate, but for others the investigation may take weeks.

After reporting you need to be prepared to access and provide records and information when requested (traceability information of plant material movements on and off the property is critical for a successful response); follow directions to manage the pest/pathogen; respect confidentiality to avoid unnecessary market reaction.

Effect on OGR

Most reports of unusual symptoms turn out to not be a biosecurity threat and there are no implications for growers. However, if a response is activated and losses are incurred because of response activities, you will be eligible for compensation under the Biosecurity Act (subject to some conditions).

Losses must be verifiable, so good production and business records are essential for compensation claims. Make sure you note where your records can be found in your absence.

Who to talk to

KVH provides regular information advice about managing identified pests/pathogens and how a response is unfolding.

NZKGI provides advice and support information to growers.

Post-harvest operators help with operations and advice.

Ensure you have stored or noted phone numbers and contact details for KVH, NZKGI and your post-harvest operator, and make sure they can be found in your absence.



KVH investigates reports of unusual symptoms to identify and manage any biosecurity risks.

Fun Fact

We’ve got brand new pest ID cards printing and coming your way shortly. The flashcards have been created to help everyone involved in orchard work improve their pest and disease ID skills – they provide an easy way to identify some of the kiwifruit industry’s biggest biosecurity risks and are a practical tool for out in the field. They’re plastic coated and durable, and held together with a ring you can adjust over time as we produce new cards and update our Most Unwanted list We’ll have these with us at upcoming events and as soon as they’re hot off the press we’ll let you know so you can order some for you and your teams.

Smart sanitising

With harvest almost done and thoughts turning to pruning and grafting, now is a perfect time to talk sanitisers. Hygiene practices including cleaning tools on arrival, and regularly between blocks, bays, and vines are a known cornerstone to protecting vines from entry of high-risk organisms, and an important discussion between growers and contractors as they agree biosecurity processes for the season. A list of sanitisers effective against biosecurity risk organisms can be found on the KVH website. This research-based information compares performance of sanitisers on wood, plastic, tyre, and metal surfaces and so allows growers to choose the most suitable product for their use. Some good news also as the plastic holsters fabricated by a Katikati firm to provide a simple and effective solution to ensure tools are regularly sanitised are still available, with orders being taken now. Sanitiser solution is added to the holsters and topped up as required avoiding the need for staff to carry separate buckets or bottles up and down rows, creating a win-win for staff and orchard owners. To find out more about availability and prices email Frank at Hercules Tanks.

Biosecurity learnings from Australia

Earlier this month, KVH visited Cairns to attend the Plant Biosecurity Research Initiative (PBRI) Symposium. This two-day event is held every two years to highlight research outcomes from PBRI’s $69M investment in plant biosecurity. The event also provides KVH with an excellent opportunity to stay engaged with our Australian counterparts in research, industry, and government. Northern Queensland is a focal point for biosecurity in the banana industry, which is under threat from a soil borne pathogen, known as Panama disease Tropical Race 4 (TR4). KVH visited some banana farms (as they are referred to) and was kindly hosted by Howe Farms to see what lessons we could incorporate into our own biosecurity preparedness for kiwifruit threats. TR4 has been sweeping through banana production regions around the world and was first detected in Australia in 1997 where it decimated the local banana industry. In 2015, TR4 was detected in Northern Queensland where 95% of Australia’s bananas are grown. The initial response was a scorched earth policy where the infected property was purchased by the industry and all host material (banana plants) removed and the earth left bare to prevent further transmission. While this approach may have slowed the spread, it has not eradicated the disease which is now known to be present on five properties in Northern Queensland. While the pathogen is not considered eradicable, the coordinated approach between Federal and State Governments, alongside industry has been effective in slowing the spread compared to all other regions where this pathogen has been detected. As a soil borne pathogen, on-orchard practices are focused at preventing the movement of soil and plant material between properties. Visiting banana farms provided KVH with an excellent learning opportunity to observe the practices used to combat a threat that is spread this way. Where applicable, KVH will look to incorporate these learnings into our readiness plans for other soil borne pathogens such as Ceratocystis fimbriata, which is considered our number one pathogen threat and has caused significant impact to kiwifruit growers in Brazil, as well as a wide range of other hosts around the world.
