2    GENE RAL CONDITIONS FOR ALL PLANT PRODUCTS  
 
All plants and pl ant products are PROHIBITED  entry into New  Zealand, unl ess an import health 
standard has been issued in accorda nce wi th Sectio n 24A of the Biosecurity Act 1993.  Should 
prohibited plants or plant prod ucts be intercepted by MPI, the importer will be offered  the option 
of reshipment or destruction o f the consign ment.  
 
The national plant protection organisation of the  expor ting coun try is requested to inform MPI of 
any change in its address.  
 
The national  plant protection organisation of the exporting country is required to inform MPI of 
any newly rec orded organis ms which may infest/infect any commodity approved for ex port t o 
New  Zealand. 
 
Pursuant to the Hazardous Substances and New Organisms Act 1996, pr oposals for the deliberate 
introduction of new organisms  (including genetically modified organisms ) as defined by the Act 
should be referred to  the Environmental Prote ction Authority .

 3    EXPLANATION OF PEST CATEGORIES  
 
MPI has ca tegori sed organ isms associated with plants and plant products into regulated and non -
regulated organisms as described below. Organisms (includin g weeds) associated with each 
commodity wi ll appear on a separate pest list which will be attached to each impor t heal th 
stand ard as an Appendix. Weeds may be in the form of seeds or other plant part s. 
 
3.1    REGULATED ORGANISMS  
 
Regulated organisms are those organisms for which phytosanitary ac tions would b e undertaken if 
they were intercepted/detected.  These will  inclu de new  organisms as defined by the Hazardous 
Substances and New Organisms Act 19 96. Regulated organisms are sub -divided into the 
follow ing groups:  
 
3.1.1    Quarantine: Risk gro up 1 pests  
 
Risk group 1 pests are those regulated pests (FAO Glossary of  Phyto sanitary Terms, 1996) which 
on introduction into New Zealand could cause unacce ptable economic impacts on the production 
of a commodity /commodities and/or the environment.  
 
3.1.2    Quaranti ne: Risk group 2 pests  
 
Risk group 2 pests are those regulat ed pes ts wh ich on introduction into New Zealand could cause 
a major disruption to mar ket access (some importing countries require specific pr e-export 
phytosanitary treatments) and/or significant e conomic impacts on the production of a particular 
commodity/ commod ities and/or the environment.  
 
3.1.3    Quarantine: Risk group 3 pests  
  
Risk g roup 3 pests (e.g. economically significant species of f ruit flies) are those regulated pests 
whic h on entry in to New Zealand would cause a major disruption to market acce ss for  a wide 
range of New Zealand commodities and/or have significant economic impac ts on their production 
and/or the environment (some impo rting countries prohibit the entry of the host commodit y).  An 
official surveillance system is required for such pe sts in  New Zealand. 
 
3.1.4    Regulated non -quarantine pests  
 
A regulated non -quarant ine pest (denoted by "reg." on the pest list) is a pest whose presence in a 
consignment of plants for planting,  affects the intended use of those plants with an economical ly 
unaccept able impact and is therefore regulated within the territory of the importi ng contracting 
party (Revised IPPC definition, Rome 1997 ). These pests would be under official co ntrol by the 
use of a Government operated or audited certification scheme.  
 
3.1.5    Regu lated non plant pests  
 
Regulated non plant pests are those organisms which, although not pests of plants or plant 
products, m ay be associated with plants or plant prod ucts in inter national trade, and may have an 
affect on human or animal hea lth (e.g. black  widow spider) and thus fall under the jurisdiction of 
other New Zeal and government departments. The categorisation of these  organisms and their 
associated import res trictions wil l be applied in accordance with the requirements of the releva nt 
departments.

(Biosecurity Act 1993)   ISSUED : 24 July 2023   Page 3 of 16 
 3.1.6    Vectors of associated quarantine pests  
 
In the context of  this import health standard, vectors are those organism s which are able to 
transmit regulated pes ts into New Z ealand.  To prevent the transmission of vectored quarantine 
organism s to susc eptible commodities in New Zealand, it is necessary to prevent the e ntry of their 
vectors.  Vectors (denoted by "vect." on t he pest list) will be categorised as risk group 1 even if 
they are present in New Zealand, unless they are risk group 2 pest s in thei r own right.  If the 
vectored organism is not present in the export ing country then the associated vector(s), if present 
in New Zealand, will be categorised as a non -regulated no n-quarantine pest(s).  
 
3.1.7    Vectored organisms  
 
Vectored org anisms  (denoted  by "VO" on the pest list) are those regulated pests that are able  to 
enter New Zealand via a vector associated with the i mported commodity.  
 
3.1.8    Strains of pe sts 
 
Where th ere is documented evidence that a pest associated with the impor ted co mmodity h as a 
different host range, different pesticide resistance, vectors  a different range of organisms, or is 
more virulent tha n that of the same species present in New Zealand, then  the different strain 
(denoted by "strain" on the pest list) of that p est will be categorised accordingly as a risk group 1 
or 2 regulated pest.  
 
3.1.9    Unidentifiable organisms  
 
Should identificatio n of an organism not be possible within th e required ti me frame, the organism 
will be categorised as a regulated pest ( either  risk gro ups 1, 2, or 3) until such time as shown 
otherwise.  
 
3.1.10    Unl isted organisms  
 
Should an organism be intercepted that is not included on the pest list for that commodity, it  will 
be categorised into the appropriate risk group and action taken according ly. 
 
3.2    NON -REGULATED ORGANISMS  
 
Non-regulated organisms are t hose organisms for which phytosanitary actions would not  be 
undertaken if they were intercepted/de tected.  Thes e would include new organisms which could 
not establish in New Ze aland.  Non-regulated organisms are sub -divided into the following 
groups:  
 
3.2.1    Non -regulated non -quarantine pests  
 
Non-regulated non-quarantine pests are either already pr esent in New Zealand and are not under 
official control or, could not establish  in New Zealand . 
 
3.2.2    Non -regulated non plant pests  
 
Non-regulated non pla nt pests are not pests of plants and are not of concern to the Ministry for 
Primary Industries  or any other New  Zealand government department.

(Biosecurity Act 1993)   ISSUED : 24 July 2023   Page 4 of 16 
 3.3    CONTAMINANTS (INCLUDING S OIL)  
    
Consig nments contaminated with soil, or other potential carriers of re gulated pests ( e.g. leaf 
litter) will not be permitted e ntry if the level of contamination is abov e the accepta ble tolerance.  
 
4    APPLICATION OF PHYTOSANITARY MEASURES  
 
A numb er of  different  phytosanitary measures may be applied to pests in each risk gro up, 
depending on the commodity and the type of pest.  These measures include:  
 
4.1    QUARANTINE: RISK GROUP 1 PESTS  
 
Phytosanitary measures required for risk group 1 pests may i nclude: 
 
- inspection and phytosanitary certification of the consignment accor ding to appropriate 
procedures by the national plant pro tection organisation of the exporting coun try, 
- testin g prior to export for regulated pests which cannot be readily detec ted by inspecti on 
(eg. viruses on propagating material from accredited facilit ies), and verified by an 
additional declaration, to that  given on the phytosanitary certificate,  
-  inspection/ testing of the consignment by MPI prior to biosecurity clearance, t o ensure 
the sp ecified pest tolerance has not been exceeded.  
 
4.2    QUARANTIN E: RISK GROUP 2 PESTS  
 
Phytosanitary measures required f or risk group 2 pests may include all the requirements for risk 
group 1 pests and may also require pre -export pest control  activities to be undertaken by the 
contracting party, and confirmed by additi onal declarations to the phytosanitary certificate.  
 
4.3    QUARANTINE: RISK GROUP 3 PESTS  
 
Phytos anitary measu res applied to risk group 3 pests may include all the requirements for risk 
group 1 pests plus:  
 
- the application of a pre -export treatment whic h has been developed in accordance with 
an approved Mini stry for Primary Industries  standard,  
- an official bil ateral quarantine arrangement between MPI and Australia national pl ant 
protection organisation which includes descriptions of each approved treat ment 
system(s),  
- specific additional declarations on th e phytosanitary certificate.  
 
4.4    REGUL ATED NON -QUAR ANTINE PESTS  
 
Phytosanitary measures applied to regulated non -quara ntine pests wil l generally be the same as 
for risk group 1 pests, or according  to the contingencies implemented for that pest if detec ted in 
New Zealand.  
 
4.5    NON -REGULATED NON -QUARANTIN E PESTS  
 
No phytosanitary measures are applied to non -regulated non -quarantine pes ts.
