2    GENERAL CONDITIONS FOR ALL PLANT PRODUCTS  
 
All plants and plant products are PROHIBITED  entry into New Zealand, unle ss an import health 
standard has been issued in accordance with Section 24A of the Biosecurity Act 1993.  Should 
prohibited plants or plant products be intercepted by MPI, the importer will be offered the option 
of reshipment or destruction of the consignm ent. 
 
The national plant protection organisation of the exporting country 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 recorded organism s which may infest/infect any commodity approved for export to 
New  Zealand.  
 
Pursuant to the Hazardous Substances and New Organisms Act 1996, proposals for the deliberate 
introduction of new organisms (including genetically modified organisms) as defined b y the Act 
should be referred to  the Environmental Protection Authority.  
 
Note: 
In order to meet the Environmental Protection Authority's requirements the scientific name (i.e.  
IHS F resh Fruit/Vegetables.  Watermelon, Citrullus lanatus  from Australia   
(Biosecurity Act 1993)   ISSUED: xx May 2019   Page 2 of 15 
 genus and species) of the commodity must be included in the phytosanitary certif icate.  
 
3    EXPLANATION OF PEST CATEGORIES  
 
MPI has categorised organisms associated with plants and plant products into regulated and non -
regulated organisms as described below.  Organisms (including weeds) associated with each 
commodity will appear on a  separate pest list which will be attached to each import health 
standard as an Appendix.  Weeds may be in the form of seeds or other plant parts.  
 
3.1    REGULATED ORGANISMS  
 
Regulated organisms are those organisms for which phytosanitary actions would be  undertaken if 
they were intercepted/detected.  These will include new organisms as defined by the Hazardous 
Substances and New Organisms Act 1996.  Regulated organisms are sub -divided into the 
following groups:  
 
3.1.1    Quarantine: Risk group 1 pests  
 
Risk group 1 pests are those regulated pests (FAO Glossary of Phytosanitary Terms, 1996) which 
on introduction into New Zealand could cause unacceptable economic impacts on the production 
of a commodity/commodities and/or the environment.  
 
3.1.2    Quarantin e: Risk group 2 pests  
 
Risk group 2 pests are those regulated pests which on introduction into New Zealand could cause 
a major disruption to market access (some importing countries require specific pre -export 
phytosanitary treatments) and/or significant ec onomic impacts on the production of a particular 
commodity/commodities and/or the environment.  
 
3.1.3    Quarantine: Risk group 3 pests  
  
Risk group 3 pests (e.g. economically significant species of fruit flies) are those regulated pests 
which on entry int o New Zealand would cause a major disruption to market access for a wide 
range of New Zealand commodities and/or have significant economic impacts on their production 
and/or the environment (some importing countries prohibit the entry of the host commodity ).  An 
official surveillance system is required for such pests in New Zealand.  
 
3.1.4    Regulated non -quarantine pests  
 
A regulated non -quarantine 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 economically 
unacceptable impact and is therefore regulated within the territory of the importing contracting 
party (Revised IPPC definition, Rome 1997).  These pests would be under official control by the 
use of a Government operated or audited certification scheme.  
 
3.1.5    Regulated non plant pests  
 
Regulated non plant pests are those organisms which, although not pests of plants or plant 
products, may be associated with plants or plant products in intern ational trade, and may have an 
affect on human or animal health ( e.g. black widow spider) and thus fall under the jurisdiction of 
other New Zealand government departments.  The categorisation of these organisms and their 
associated import restrictions will  be applied in accordance with the requirements of the relevant  
IHS F resh Fruit/Vegetables.  Watermelon, Citrullus lanatus  from Australia   
(Biosecurity Act 1993)   ISSUED: xx May 2019   Page 3 of 15 
 departments.  
 
3.1.6    Vectors of associated quarantine pests  
 
In the context of this import health standard, vectors are those organisms which are able to 
transmit regulated pests into New Ze aland.  To prevent the transmission of vectored quarantine 
organisms to susceptible commodities in New Zealand, it is necessary to prevent the entry of their 
vectors.  Vectors (denoted by "vect." on the pest list) will be categorised as risk group 1 even i f 
they are present in New Zealand, unless they are risk group 2 pests in their own right.  If the 
vectored organism is not present in the exporting country then the associated vector(s), if present 
in New Zealand, will be categorised as a non -regulated non -quarantine pest(s).  
 
3.1.7    Vectored organisms  
 
Vectored organisms (denoted by "VO" on the pest list) are those regulated pests that are able to 
enter New Zealand via a vector associated with the imported commodity.  
 
3.1.8    Strains of pests  
 
Where the re is documented evidence that a pest associated with the imported commodity has a 
different host range, different pesticide resistance, vectors a different range of organisms, or is 
more virulent than that of the same species present in New Zealand, then the different strain 
(denoted by "strain" on the pest list) of that pest will be categorised accordingly as a risk group 1 
or 2 regulated pest.  
 
3.1.9    Unidentifiable organisms  
 
Should identification of an organism not be possible within the required tim e frame, the organism 
will be categorised as a regulated pest (either risk groups 1, 2, or 3) until such time as shown 
otherwise.  
 
3.1.10    Unlisted 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 accordingly.  
 
3.2    NON -REGULATED ORGANISMS  
 
Non-regulated organisms are those organisms for which phytosanitary actions would not be 
undertaken if they were intercepted/detected.  These  would include new organisms which could 
not establish in New Zealand.  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 present in New Z ealand and are not under 
official control or, could not establish in New Zealand.  
 
3.2.2    Non -regulated non plant pests  
 
Non-regulated non plant 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: xx May 2019   Page 4 of 15 
  
3.3    CONTAMINANTS (INCLUDING SOIL)  
    
Consignments contaminated with soil, or other potential carriers of regulated pests ( e.g. leaf 
litter) will not be permitted entry if the level of contamination is above the acceptab le tolerance.  
 
4    APPLICATION OF PHYTOSANITARY MEASURES  
 
A number of different phytosanitary measures may be applied to pests in each risk group, 
depending on the commodity and the type of pest.  These measures include:  
 
4.1    QUARANTINE: RISK GROUP 1 P ESTS  
 
Phytosanitary measures required for risk group 1 pests may include:  
 
- inspection and phytosanitary certification of the consignment according to appropriate 
procedures by the national plant protection organisation of the exporting country,  
- testing  prior to export for regulated pests which cannot be readily detected by inspection 
(eg. viruses on propagating material from accredited facilities), and verified by an 
additional declaration, to that given on the phytosanitary certificate,  
-  inspection/t esting of the consignment by MPI prior to biosecurity clearance, to ensure 
the specified pest tolerance has not been exceeded.  
 
4.2    QUARANTINE: RISK GROUP 2 PESTS  
 
Phytosanitary measures required for risk group 2 pests may include all the requirements f or risk 
group 1 pests and may also require pre -export pest control activities to be undertaken by the 
contracting party, and confirmed by additional declarations to the phytosanitary certificate.  
 
4.3    QUARANTINE: RISK GROUP 3 PESTS  
 
Phytosanitary measur es applied to risk group 3 pests may include all the requirements for risk 
group 1 pests plus:  
 
- the application of a pre -export treatment which has been developed in accordance with 
an approved Ministry for Primary Industries  standard,  
- an official bila teral quarantine arrangement between MPI and Australia national plant 
protection organisation which includes descriptions of each approved treatment 
system(s),  
- specific additional declarations on the phytosanitary certificate.  
 
4.4    REGULATED NON -QUARA NTINE PESTS  
 
Phytosanitary measures applied to regulated non -quarantine pests will generally be the same as 
for risk group 1 pests, or according to the contingencies implemented for that pest if detected in 
New Zealand.  
 
4.5    NON -REGULATED NON -QUARANTINE  PESTS  
 
No phytosanitary measures are applied to non -regulated non -quarantine pests.

pests.  
 
The package should not be opened in transit.  However, where a consignment is either stored, 
split up or has its packaging changed while in another country (or countries) en route  to New 
Zealand, a "Re -export Certificate" is required.  Where a consignment i s held under bond, as a 
result of the need to change conveyances, and it is kept in the original shipping container, a "Re -
export Certificate" is not required.  
 
6.3    INSPECTION ON ARRIVAL  
 
MPI will check the accompanying documentation on arrival to confi rm that it reconciles with the 
actual consignment.  
  
IHS F resh Fruit/Vegetables.  Watermelon, Citrullus lanatus  from Australia   
(Biosecurity Act 1993)   ISSUED: xx May 2019   Page 8 of 15 
 MPI requires, with 95% confidence, that not more than 0.5% of the units (for watermelon, a unit 
is one fruit) in a consignment are infested with visually detectable regulated pests.  To achieve 
this, MPI will sample and inspect 600 units with an acceptance level of zero infested units (or 
equivalent), from the (homogeneous) lot.  
 
6.4    BIOSECURITY/QUARANTINE DIRECTIVE  
 
The commodity may be directed to a facility for further treatment if required.  
 
6.5    TESTING FOR REGULATED PESTS  
 
MPI may, on the specific request of the Chief Technical Officer , test watermelon (commodity 
subclass: fresh fruit/vegetables) from Australia for regulated pests.  
 
6.6    ACTIONS UNDERTAKEN ON THE INTERCEPTION/DETECTION OF 
ORGA NISMS /CONTAMINANTS  
 
If regulated pests are intercepted/detected on the commodity, or associated packaging, the 
following actions will be undertaken as appropriate:  
 
6.6.1    Quarantine: Risk group 1 pests  
 
If a risk group 1 pest is intercepted, the importe r will be given the option of: - 
 
- treatment (where possible) of the consignment at the importer's risk,  
-  re-sorting (specific conditions apply) of the consignment,  
- reshipment of the consignment,  
-  destruction of the consignment.  
 
6.6.2    Quarantine:  Risk group 2 pests  
 
If a risk group 2 pest is intercepted, the importer will be given the option of: - 
 
- treatment (where possible) at the discretion of the Chief Technical Officer  and 
immediate feedback to the national plant protection organisation of th e exporting country 
with a request for corrective action,  
-  reshipment of the consignment,  
-            destruction of the consignment.  
 
6.6.3    Quarantine: Risk group 3 pests
