 Part A. Background  
Scope  
This document describes the requirements to be met to enable biosecurit y clea rance to be given 
for fre sh lychee  fruit (Litchi  chine nsis) for human consumption imported into N ew Zealand from 
Thailand . The commodity description “ lychee ” for human consumption is defined as 
commercially produced lychee fruit with calyx and pedunc le, bu t without st ems, leaves, roots or 
any other plan t parts.  
Definitions  
The definitions of relevant  phytosanitary terms used in  this standard are consistent with the terms 
stated in the International Standards for Phytosanitary Measures No.5 , produced by the  
Internation al Plant Prot ection Co nvention (IPPC ), unless the context otherwise requires or the 
definition is stated below.  
Import health standard  means a document issued pursuant to section 2 4A (formerly s ection 22)  
of the Biosecurity Act 1993 on be half o f the Direct or Gen eral pe rmitting entry to New  Zealand  of 
a specific product un der certain condit ions.  
MPI Import and Export Stan dards means the sec tion within the Ministry for Primary Industries  
which is responsible for regulatory biosecurity functi ons. 
Maximum allow able p revalen ce means the level of  infesta tion th at is the threshol d, above which 
phytosanitary actions based on insp ection would be app lied. 
Unit means one lychee  fruit.  
Regulated organisms  means those organisms for which phytosanitary a ctions  would be 
undertak en if t hey were intercepted/ detected . 
Outco me 
The agreed pre -shipment phytosani tary measures for specific regul ated pests have bee n 
undertaken and the lychees are  free of all regulated pests.  
Performance measure  
The high risk regula ted or ganisms as i n Part C require speci fic risk mit igation measure s.  
 
The Maximum A llowable Prevalenc e for visually detectable regula ted organisms on fr esh 
fruit/vegetables is as follows: At a 95% confidence level, not more than 0.5% of the units in the 
consig nment are in fested  (this equates t o an accepta nce leve l of ze ro units infested by regulated 
organ isms in a sample size of 600 uni ts).

 Equivalence  
A chief technical officer may consi der an application for an equivalent phytosanitary measure to 
be approved in accordance with 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 measure( s).  
Equivalence will be considered with reference to the International Standard for Phytosanitary 
Measures (ISPM) 24. Guideline s for the determination and recognition of equivalence of 
phytosanitary measures . 
Part B. Genera l phytos anitary  import requiremen ts for all fresh 
fruit and vegetables for consumpt ion 
The import heal th standard 152.02 (IHS152.02: Importa tion and Clearance o f Fresh Fruit and 
Vegetables into New  Zealan d) con tains t he ph ytosanitary r equirements that must  be met for all  
fresh fruit and v egetable commoditi es that are allowed to be import ed into New Zealand . The 
IHS 152.02 outlines transit requ irements, inspection s on arrival in New Zealand and actions 
unde rtaken  upon o rgani sm intercepti ons. 
 
The import heal th stand ard 152 .02 can be found a t the MPI website 
(http://www.biosecuri ty.govt.nz/files/ihs /152-02.pdf ). 
Part C. Additional requiremen ts for  lychee  from  Thailand  
Phytosanitary measures  
All lyche e fruit  for export to New  Zealand must be s ourced from orchards that produc e 
commercial lychee  fruit under standard cultivation, pes t-control, harvestin g and packing 
activities. During harvest, in fested , infec ted o r damaged fru it must be discarded prior to  
treatm ent.  
MPI requires  a mandatory pre -export treatment of lychee fruit for high risk regul ated organisms, 
including economically  significant fruit f ly species. MPI currently approves vapour he at 
treatment or co ld disinfesta tion or irradiation a t the fo llowing  specifications  for fruit flies :  
Vapour heat 
treatment  (VHT)  Lychee s must be treated with vapour heat and the temperature mu st be raised from am bient 
to 47 °C or greater and held for a min imum o f 20 mi nutes .  
 
Cold dis infestation  Prior to arrival in New Zealand, the core temperature of the  fruit must be held continuously  at 
one of the following temperature/time combinations:  
Fruit pulp temperatu re held at:  
1 °C or below for 17 days  
1.38 ° C or b elow fo r 20 days 
 
Irradi ation  Irradiation with a mini mum dos e of 150 Gy

 MPI requires specif ic pre-export phytosanitary meas ures for Conogethes punctiferalis . MPI 
currently approves t he use of in -field p est control for Lepidoptera species through out th e 
produ ction  season or irradiation at a mi nimum dose rate of 289 Gy.  
MPI requires specific pre -export phytosanitary measu res for fruit flies of economic signif icanc e. 
MPI currently appro ves vapour  heat trea tment ( Appendix 1  of OAP ); or cold disinfestation  
(Appen dix 2 of OAP ); or irradiation (A ppendix 4  of OAP ); these  measu res are to be carried out 
in ac cordance with IHS  152.02 and the official assuranc e programme.  
The application of the  irradiation treatmen t (Appendix 4  of OAP ) must be carried out in 
accordance with ISPM  18. Guidelines fo r the use of irradiation as a phytos anitary measur e.  
MPI a pprove s the below irradiat ion doses :  
- Fruit flies with a m inimum dose of 150 Gy  
- Conogethes  punctiferalis  with a mi nimum dose of 289 Gy 
- Other IHS regulated arthropod pests1 with a minimum d ose of 400 Gy  
Inspection of the  consignment  
Once the phytos anitary measures hav e been undertaken for high risk regulated organisms, the 
Thailand NPP O is requir ed to sample and visual ly inspect the consignment according  to official 
procedur es for all r egulated pest s including those  listed in Part E, to ensure it meets 
New Zealand’s current import requirements. Wh ere Appendi x 4 of OAP  (irradiation ) is the 
phytosanitary measure to be  undertaken, inspectio n will  occur pre t reatment . Whe re a regulated 
arthropo d pest is dete cted on the co mmodity and Appendix  4 of OAP  (irradiation) is the intended  
pre-export phytosanitary measure,  appropriate irradiatio n dosages must be applied by Thailan d’s 
NPPO. Alternative approve d corr ective actio ns may be con ducted (e.g. meth yl bro mide 
fumigatio n), or the fru it shall not  be expo rted to New Zealand.  
Where Appe ndix 2 of OAP  (cold disinfestation ) is the p hytosanitary measure to be undertaken, 
inspection  will occur pre or post application of the phytosanita ry measure ; inspection will oc cur 
after phytosanit ary meas ure ha s been undertaken fo r Appendix 1 of OAP  (vapour heat treatm ent).  
A phytosanita ry certificate sh ould not be issued if live regulated organ ism(s) are detected , unless 
the consignment  is effectively tr eated. If org anisms are found which are not listed  in the IHS 
Thailand’s NPPO must e stablish their regulatory status  by consulting the M PI “Official 
New  Zealand Pest Register ” (ONZPR ), online at https: //onzp r.mpi. govt.nz/ .  
If an organism is not listed in  ONZPR , Thailand’s NPPO must  contact MP I to establish the 
regulatory statu s of the organism.  
Part D. Phytosanitary certification  
A completed phytosanit ary certi ficate issued by Th ailand’s NPPO m ust ac company all lychee 
consig nments exported to New Zealand . The phytosanitary certific ate must be  in English and 
must be an original . Bilingual certifi cates are acceptable as  long as English is one of the 
langu ages.

MPI will  inspect documentat ion on arrival in New Z ealand . In addition, MPI may inspect  a 
sample from  each lot  on arrival  in New Z ealand  to verify requirements o f the IHS have been met.  
 
Actions undertaken upon inter ception of irradiated regulated pests  
As the re quired response of r egulated arthropod pest s that have undergone the irradiatio n 
treatment is preventi on of adult  emergenc e or a dult steril ity (not morta lity) a possibility exists 
that live (but infertile or unable to em erge from pupation ) regulated arthro pods may be present in 
a consignment.  
In accordance with section 8.3 of ISPM 1 8 (20 19) when mortality  is not the  required  respo nse, 
the de tection of liv e stages of regulated  pests in import inspection should  not be cons idered to 
represent treatment failur e resulting in non -compliance unless eviden ce exists to indicate that the 
integ rity o f the treatment s ystem was i nadequate .
