Wollemia nobilis (Wollemi Pine) - Biosecurity New Zealand

asymptomatic organisms being associated with the imported nursery stock on its arrival in
New Zealand. Nursery stock found to harbour organisms or families of organisms of
potential non-negligible phytosanitary risk would then be treated or excluded from import
into New Zealand based on the assumption that any such contamination indicates a failure in
the pre-export production system.
3.5 Risk Assessment of Hazards
The risk assessment for each hazard or hazard group is contained in chapters 4 to 12 of this
risk analysis. The following sections describe aspects of the risk assessment of imported
Wollemia nobilis nursery stock from Australia that are common to all of the identified
hazards or hazard groups.
3.5.1 Assessment of Risk of Entry
Figure 3.2 below provides a simple overview of the risk attributes of the pathway for the
entry of hazard organisms associated with Wollemia nobilis nursery stock imported from
Australia.

Wollemia nobilis nursery stock imported from Australia.
In essence for the nursery stock being exported to New Zealand to be a biosecurity risk to
New Zealand, hazard organisms would have to become associated with the nursery stock in
Australia before production or during transport, and survive the journey to New Zealand.
