    14 August 2023  
Ministry for Primary Industries    Page 3 of 28 Introduction  
This introduction is not part of the Import Health Standard (IHS) but is intended to indicate its general effect.  
Purpose  
This IHS specifies the import requirements for the importation of dried and preserved plant material from all 
countries.  
Backgro und 
An IHS issued under the Biosecurity Act 1993 (the Act) , specif ies the  requirements to be met to effective ly 
manage biosecurity risks associated with importing goods , including the risks from incidentally imported 
organisms. IHSs may include requirements that must be applied before importation before  the movement to a 
transitional facility or before biosecurity clearance.  
Post clearance conditions may also be specifie d in an IHS.  
Guidance boxes throughout the IHS provide information on how the requirements may be met.   
Who should read this?  
Anyone who is involved in the process of importing dried and preserved plant material s into New Zealand 
should read and be familiar with this IHS.    
Why is this important ? 
It is the responsibility of the importer to ensure that risk goods comply with the requirements of the relevant 
IHS. Risk goods that do not comply with the requirements of an IHS may not be cleared for entry in to New 
Zealand and may be directed for treatment, re -shipment, destruction or further action deemed appropriate by 
a chief technical officer (CTO).  
The pathway may be suspended if certain types of viable regulated pests or viable unwanted organisms are 
intercepted on a consignment.  
Importers are liable for all associated expenses . 
Equivalence  
A CTO may consider an application for an equivalent phytosanitary measure to be approved, different from 
that provided for in this IHS, to maintain at least the same level of protection assured by the current measures.  
The CTO may issue a direction under section 27(1)(d) of the Act, setting out specific measures different from 
those set out in this IHS, to be applied to effect ively manage risks associated with specified goods.  
Document history  
Refer to Appendix 2 for the A mendment Record for this IHS.  
 
       
 Import Health Standard: Dried and Preserved Plant Material  
    14 August 2023  
Ministry for Primary Industries    Page 4 of 28 Other information  
Plant material containing controlled substances are also regulated by the Misuse of Drugs Act (1975)  and 
require permission from the Ministry of Health prior to importing.  
Convention on International Trade in Endangered Species (CITES)  
Endangered and threatened plant species are regulated by the Convention on International Trade in 
Endangered Species of Wild Fauna and Flora   
Note: It is the importers responsibility to be familiar with and comply with all New Zealand laws as this is not an 
exhaustive list of compliance requirements.
