The power of DNA-based testing is that it allows for rapid test turnaround times, while ensuring a high degree of test accuracy. At Hill Labs we have a team of molecular biologists working on the development of molecular biology based tests that are unique to us. We use real-time PCR technology to provide rapid and accurate testing for the presence of pathogens, and because we have a team of experts, we have the expertise to develop new diagnostic PCR tests to address industry requirements. Don't hesitate to give us a call today and find out how we can meet your testing needs.

PSA V Testing

Hill Labs is New Zealand's only provider of routine Pseudomonas syringae pv. actinidiae (Psa-V) testing. Having worked closely with industry bodies, such as Kiwifruit Vine Health (KVH), Zespri and Plant and Food since the initial Psa-V outbreak in 2011, you can be confident that our testing will meet your on orchard needs.

What should you do if you think your orchard is infected by Psa?

If you find symptoms on your orchard, tag the vine and contact your pack house Psa Manager for confirmation that the symptoms are Psa-like. The pack house either takes the sample or organises for a sample to be taken. The pack house will also organise for the sample to be sent to Hill Labs. Alternatively you can take the sample yourself and send it directly to the laboratory. Sampling details are available from KVH at the following link.

Pathogen Testing

Hill Labs has an extensive array of pathogen-related tests using molecular-based detection. Our turnaround times are industry-leading and can be used with product or environmental swabs alike. Some of our routinely analysed pathogens are listed below:

  • Listeria species (by PCR)
  • Listeria monocytogenes (by PCR)
  • Salmonella (by PCR)
  • STEC E. coli ((including O157) by PCR)

Hill News November 2023 - Update From Our CEO, Dr Jonno Hill

The cliché “change is the only constant” is as true now as it’s ever been. Within our changing climate, we have apparently just kicked over from La Nina to El Nino, which is likely to lead to more rain on the west coast and more drought on the east. Hats off to our farmers, who must do the best they can within unpredictable and sometimes severe weather events.
