Movement of plants and plant material to orchards where Psa is not detected, and to the South Island, is strictly prohibited or restricted.

Latest news


The kiwifruit industry has introduced biosecurity controls to reduce the risk of pests and diseases being spread through the movement of nursery plants and shelter plants. The Kiwifruit Plant Certification Scheme (KPCS) is a major component of this and ensures all nurseries selling kiwifruit plants and shelter plants are managing biosecurity risk.

There are also biosecurity controls for growers to manage the risk associated with smaller volumes of plant movements and to do so in a manner that is not unnecessarily restrictive on orchard operation.

The movement of plant material is considered a high-risk pathway for transporting pests and pathogens over long distances. This includes known threats such as Cherry Leaf Roll Virus and Psa, but also other threats that may be present in New Zealand but not yet detected, such as Ceratocystis fimbriata.

There are three options available for sourcing or producing nursery plants:

  • KPCS “Full Certification”
  • KPCS “Restricted Certification”
  • Grow for your own use – for smaller volumes and restricted movements subject to meeting risk management requirements.

When sourcing shelter plants for a kiwifruit orchard there are two options:

Without biosecurity controls on internal pathways, a new pest or pathogen is likely to be widespread by the time it is detected and the window for eradication may have been missed. Because of this, all nurseries and growers must meet their biosecurity responsibilities and maintain traceability when moving rootstocks.

Information for growers

KPCS information for growers is available here.

Growers wishing to purchase plants must use this list for nurseries who have met KPCS Certification requirements.

A number of nurseries have indicated they intend to join the KPCS scheme for future supply. Growers are able to order plants from nurseries in transition, however plants are not able to move off the property until the nursery has met KPCS requirements.

When receiving plants from a nursery, growers should maintain traceability and record where on their orchard the plants have been planted.

Grow for your own use

Growers can grow plants on the property they are to be used on without any KVH controls.

Growers can also move plants between KPINs under the same ownership (but only to a maximum of 1000 plants per year).

Traceability records must be maintained but there are no registration or certification requirements.

If more than 1000 plants per year are moved between a growers properties or plants are moved to another grower then the grower must become a KPCS nursery.

Information for Nurseries

A nursery is defined as any person or other entity that propagates Actinidia plant species to any age for sale or movement outside of the property. All kiwifruit nurseries are subject to specific requirements and movement controls. Only certified plants may be sold, although growers are still able to produce plants for their own use.

There are two options for certified plants under the KPCS:

  • KPCS “Full Certification”– certified plants that meet all the testing requirements of all target organisms. These can be moved between regions in accordance with KVH movement controls.
  • KPCS “Restricted Certification”– plants produced under the KPCS Standard, and certified free from all target organisms, except the common New Zealand strain of Psa-V. Plants meet the same standard as above and all testing requirements, but may have the common New Zealand form of Psa-V, provided they are free of non-New Zealand Psa forms and strains resistant to Streptomycin or Copper. These plants can only be moved to Psa-V positive orchards.

To achieve KPCS certification

  • Complete the KPCS nursery manual and submit to KVH for review
  • Be independently audited
  • Have plants sampled and tested by KVH annually prior to dispatch

Reminder to remove unpicked fruit

Growers are reminded that unpicked kiwifruit should be removed from vines to help limit wild kiwifruit plants establishing in nearby areas, especially around native bush, or forestry. Fruit ripening over the winter months provides a food source for birds (such as the wax-eye/tauhou) that then spread seed through their droppings, together with a small fertiliser package. A proportion of this seed can readily germinate. Unpicked fruit needs to be dropped to the ground and mulched. This prevents mass-feeding by birds over the entire winter period.

Biosecurity tops agribusiness priority list again

Biosecurity has retained the number one ranking in KPMG’s annual Agribusiness Agenda priorities survey for the 15th consecutive year. With a priority score of 9.16 (the highest since 2021) the issue was raised in many of the roundtable discussions with leaders. KPMG notes that while great progress has been made in eliminating Mycoplasma Bovis, and the devastation that Psa inflicted on kiwifruit is becoming a distant memory, the likely arrival of avian influenza has brought preparedness for a major incursion into sharp focus. In addition to the increased risk of incursion, contributors noted that in the aftermath of Cyclone Gabrielle a range of new disease issues appear to have arisen. These are potentially sleeper diseases that have been triggered by the consequences of the cyclone. The nature of the biosecurity risks we face is changing faster than we are evolving our ability to respond. As incursions become less likely to follow traditional vectors and arrive via a port or airport, the capabilities needed to identify an incursion and respond must evolve and we must have fit for purpose emergency response plans. Also, the report makes specific note that it is critical that each organisation focuses on doing the things they can do in their business well. In responding to Covid-19, it was the small things like washing hands and wearing masks that did the most to protect us from infection. With the threats we face, it will be good farm management practices and hygiene standards that will offer the most protection. These key areas of response capability, planning, and the importance of consistent best practice are all main areas of discussion at the upcoming KVH Biosecurity Symposium. You can register now to save your spot - and the symposium programme is on our website now!
