 Part A. Background  
Scope  
This document describes t he req uirements to be met to enable biosecurity clearance to be given 
for fresh longan  fruit (Dimocarpus longan ) for human co nsumption import ed into New Ze aland 
from Thailand. The commodity description “ longan ” for human consumption is defined as 
commercia lly pr oduced longan ( Dimocarpus longan ), with a maximum of 15cm panicle attached 
to the fruit  but without stems, leaves, root s or any other p lant parts.  
Definitions  
The definit ions of relevant phytosanitary terms used in this standard are consistent with the te rms 
stated in the International Standards for Phytosanitary Measures No.5 , produced by th e 
International Plant Protecti on Convention (I PPC), unless t he context otherwise r equires or the 
definition is stated below.  
Import health standard  means a docum ent is sued pursuant to section 22 of the Biosecurity Act 
1993 on behalf of the Director General  permitting entry to New Zeala nd of a specific  product 
under  certain co nditions.  
MPI Import and Export Standards means the section within the Ministry for Primar y Indu stries  
which is responsible for regulatory biosecurity functions.  
Maximum allowable preva lence  means the level of infes tation that is t he threshold, above which  
phytosanit ary actions based on inspection would be applied.  
Unit means one longan  fruit.  
Regula ted organisms  means those organisms for which phytosanitary actions would be 
undertaken i f they were intercepted/detect ed. 
Outcome  
The agreed pre -shipment or in -transit me asures for high risk regulated organisms have been 
undertaken and the longan  are free  of regulated organisms.  
 
Performance measure  
The high risk regulated organisms as in Part C require specific risk miti gation measures.   
 
The Maximum  Allowable Prevalence for visually detectable regulated organisms on fresh 
fruit/vegetables is as fol lows: At a 95% confidence level, not more than 0.5% of the units in the 
consignment are infeste d (this equates to an acceptan ce level of zero  units infeste d by regula ted 
organis ms in a sample size of 600 units).

 Equivalence  
A chief technical officer may c onsider an application for an equivalent phytosanitary measure to 
be approved in accordance wit h section 27(1) (d)(iii) of the Act, different from that provided for 
in this IHS, to maintain at least the same level of protection assured by the current measur e(s).  
Equivalence will be considered with reference to the International Standard for Phytosan itary 
Measures (ISPM) 24. Guidelines for the determination and recognition of equivalence of 
phytosanitary measures . 
Part B. General phytosanitary  import require ments for all fresh 
fruit and vegetables for consumption  
The import health standard 152.02 (IHS 152.02: Importation and Clearance of Fresh Fruit and 
Vegetables into New  Zealand) contains t he phytosanitary requirem ents that must be  met for all 
fresh fruit an d vegetable commodities t hat are allowed to be imported into New Zealand. The 
IHS 152.02 outlin es transit requirements, inspections on arrival in New Zealand and actions 
undertaken upon o rganism interceptions.  
 
The import health standard 152.02 can be foun d at the MPI website  
(https://www.mpi .govt.nz/dmsdocument/1147 ). 
Part C. Additional requirements fo r longan from Thailand  
Phytosan itary measures  
All longan  fruit for export to New Zealand must be sou rced from orchards that produce 
commercial longan  fruit under standard cultivation, pest -contro l, harvesting  and packing 
activities. During harvest, infeste d, infected or damaged  fruit mu st be discarded prior to 
treatmen t.  
MPI requires a mandatory pre -export treatment of longan  fruit for high risk regulated organisms , 
including economically signifi cant fruit fl y species. MPI currently approves vapour heat 
treatm ent or cold disinf estation or irradiation at the fol lowing specifications  for fruit flies :  
Vapo ur heat treatment   
(VHT)  Longan s must be treated with vapour heat and the temperature must be r aised from am bient 
to 47°C or greater and held for a minimum of 20 minutes.   
 
Cold disinfes tation  Prior to arrival i n New Ze aland, the core temperature of the f ruit must be held continuously 
at one of the following temperature/time combinations:  
 
Fruit p ulp temperatu re held at:  
0.99ºC or below for 13 days  
1.38°C  or below for 18 days  
 
Irradia tion Irradiation with a m inimum dose of 150 Gy  
  
IHS Fres h Fruit/Vegetables  Longan  (Dimocarpus longan .) from Thailand   Date 
(Biosecurity Act 1993)     Page 6 of 11 
 MPI require s specif ic pre-export phytosanitary measures for Conogethes punctiferalis  (yellow 
peach moth) . MPI curr ently approves the use of in -field pest co ntrol for Lepidoptera species 
throughout the produ ction season or irradiati on at a minimum dose rate of 289 Gy.  
MPI re quires specific pre -export phytosanitary measures for fruit flies of economic impo rtance. 
MPI c urrently approves vapour heat tr eatment (Appendix 1  of OAP ); or cold disinfestation 
(Appendi x 2 of OAP ); or irradiati on (Appendix 4  of OAP ); these measures are t o be carried out 
in acc ordance with IHS 152.02 and the official assurance programme.  
The appli catio n of the irradiation treatment (Appendix 4  of OAP ) must  be carried out in 
accordance wi th ISPM 18. Guid elines for the use of irradiation as a phytosanitary measur e. MPI 
approves the following  irradiation doses  
- Fruit flies with a minimum dose of 150 Gy  
- Conogethe s punctife ralis with a minimum dose  of 289 Gy 
- Other IHS regulated arthropod pests1 with a minimum dose of 400 Gy  
Inspection of the consignment  
Once  the p hytosanitary measure s have been undertaken for the high risk regulat ed organisms, the 
Thailand NPPO  is required to sample and vi sually inspect the consignment according to official 
procedures for all re gulated pests including those listed in Part E , to ensure it conforms with New 
Zealand’s current import  requirements.  Where Appendix 4  of OAP  (irradiatio n) is the 
phytosanitary measure to be undertaken, i nspection will occu r pre treatment. Where a regulated 
arthro pod pe st is detected on the commo dity and Appendix 4  of OAP  (irradiation) is the intende d 
pre-export phytosan itary measure, appropriat e irradiation dosa ges must be applied by Thailand’s 
NPPO. Alternative  approved correctiv e actions may be conducted (e.g. m ethyl bromide 
fumigation), or the fruit shall  not be exported to New Zealand.  
Where App endix 2 of OAP  (cold disinfes tation) is the ph ytosanitary measure to be  undertaken, 
inspection will occur pre or post the phytosanitary measu re; inspection will occur a fter 
phytosanitary measure ha s been undertaken for Appendix 1  of OAP  (vapour heat treatment).   
A phyto sanitary certificate s hould not be issued if live regulated orga nism(s) are detected, unless 
the consignment is eff ectively treated. I f organisms are foun d whic h are not listed in the IHS, 
Thailand’s NPPO mus t establish their regulatory status by co nsultin g the MPI “Official New 
Zealand Pest Register ” (ONZPR ), online at https://onzpr.mpi.govt.nz /. 
If an  organism is  not listed  in ONZPR, Thailand’s NPPO must contact MPI to establish the 
regulatory status of th e organism.   
Part D. Phytosanitary certifica tion 
A compl eted phytosan itary certificate issued by Thailand’s  NPPO must accompany all longan  
consignments exported to New  Zealand. The phytosanitary certificate must be in English and 
must be an original. Bilin gual certificates are acceptable as long as English is o ne of the 
language s.

 Appendix 1: Verificat ion activities on arrival in New Zea land 
MPI will inspect docum entation on arrival in New Zealan d. In addition, MPI may inspect a 
sample from each lot on ar rival in New Zealand to verify requirements of the IHS have been met.  
 
Actions undertaken upon inter ception of irradiated regulated pes ts  
As the required re sponse  of regulated arthropod pests th at have undergone the irradiation 
treatment is prevention of adult  emergence or adult sterility (not mortality) a possibility exists 
that live (but unfertile or unable to emerge from pupation ) regulated ar thropods may be pre sent in 
a consignment.  
In accor dance with section 8.3 of ISPM 18 (20 19) when mortality is no t the required response, 
the detection of live stages of regulated  pests in import inspection should  not be considered to 
represent tre atment fa ilure resulti ng in non-compliance unless evidence e xists to indicate that the 
integrity of the treatment system was i nade quate.  
MPI reserves the right for an analysis to be conducted on the detected regulated pe st to verify 
treatment efficacy.
