Wollemia nobilis (Wollemi Pine) - Biosecurity New Zealand

Figure 3.1: The “basic” pathway for the entry into New Zealand of nursery stock.
1) Mother plants in Australia are growing:
o In a quarantine nursery;
o In a commercial nursery;
o In a home nursery or greenhouse;
o In a cultivated garden; or
o “Naturally” in a park or wilderness area.
2) Plants or plant parts are prepared for export in Australia by:
o Removing whole plants from potting mix or soil, treating (see 3a) and re-potting
in soil-less potting mix;
o Taking root-less cuttings from mature plants;
o Taking seeds from mature trees (not included in this risk analysis);
o Taking cuttings from mature plants or seedlings and placing into sterile culture
(plants in vitro);
o Germinating seeds in sterile culture (plants in vitro).
3a) Whole plants may be treated pre-export as per MAF pre-entry treatment
requirements. For whole plants this includes root washing and a number of
chemical treatments.
3b) Cuttings may be treated pre-export as per MAF pre-entry treatment requirements 12 .
4) The nursery stock is packaged and transported to New Zealand either:
o Unaccompanied by airfreight or sea cargo, or
o Accompanied by air or sea passengers.
5) Each shipment or accompanied luggage must arrive at the New Zealand border (a
place of first arrival) with the appropriate biosecurity-related papers e.g.
phytosanitary certificate attesting to the identity of the nursery stock, any treatments
completed, or any other information required to help mitigate biosecurity risks.
6) Nursery stock is examined at the port of entry to ensure packaging is compliant and
the shipment or luggage is not contaminated with organisms that can be detected on
12 Seed import requirements are excluded from consideration in this analysis. Tissue cultures do not normally
require any form of pre-entry treatment.
