Sampling and testing

Seen something unusual? Any person who identifies potential new and/or unusual disease symptoms or pests on an orchard or goods being moved, must report these to KVH within 48 hours of identification. To make a report email KVH or phone 0800 665 825.


Monitor your vines regularly, noting any suspicious symptoms.

If suspicious symptoms are found follow the process in the KVH information sheet on Psa-V sample collection and testing.

Fill in a lab submission form and send your sample to Hill Laboratories for testing (they carry out routine Psa testing weekly on a Wednesday only).

KVH pays for lab testing from the South Island, and “Not Detected” orchards in the North Island. Other testing may be approved by KVH on a case-by-case basis.

Once a KPIN has been confirmed Psa-V positive on any variety KVH will not pay for any further testing on that KPIN. Growers wishing to test other varieties on the same KPIN must pay for further testing themselves.


All lab results are sent to KVH, who upon receipt will notify the grower or relevant pack-house. If the result is ‘not detected’ growers should continue routine monitoring of their orchard and remain alert for any Psa-V symptoms.

Is your result Psa-V positive? Refer here for more information.
