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

Are you a quizmaster like our young growers?

Annual Young Grower competitions have been taking place throughout the regions over the last few weeks and we’ve had biosecurity rounds included in many of them. Congratulations to everyone who took part – it’s great to see such knowledge and enthusiasm for the importance of biosecurity. Just yesterday at the Bay of Plenty Young Grower event we provided an interactive quiz to each of the competitors, who impressed us with their on-orchard biosecurity expertise. Congratulations to Jack Canham from Apata for winning the biosecurity section on the day. How do you compare to this year’s young growers? Think you’d outdo them? Test yourself on the Connections game here (where you will need to group words that have a common thread, into four groups of four) before seeing the set of quiz questions we asked competitors here. Answers for the quiz questions can be found here. Good luck!

Mature plant movements

Winter is the time when growers look to replace plants on their orchards or plant new blocks. This article is a reminder that if these plants are being moved between properties there are biosecurity requirements that must be met to reduce the likelihood of spreading pests and diseases, including Psa. These requirements also provide the best chance of a successful response if a new organism was detected in our industry. While most kiwifruit plant movements come from nurseries, growers may occasionally move mature plants between orchards. The movement of any plants are a risk pathway, and it is important for growers to understand what’s required under the Pathway Plan, as outlined below. What does this mean for you? If you are taking mature plants from your own orchard for use on that same orchard there are no requirements under the Pathway Plan. If you are moving orchard plants from your orchard to another orchard, or source orchard plants from someone else, you need to ensure that you are meeting the requirements of the Pathway Plan – by being Kiwifruit Plant Certification Scheme (KPCS) certified for example. If you are a Psa non-detected supplier, you will need to complete a Psa test. It isn’t onerous to become certified as an orchard plant supplier and there are no costs (unless diagnostic testing is required). The new Pathway Plan requirements are very similar to existing protocols. They do require planning in advance to ensure monitoring can occur while vines have leaves and are in active growth. More information about orchard plant movement information, including the KPCS manual and supporting documents, is available here.
