Introduction 
This introduction is not part of the  import health standard (IHS) , but is intended to indicate its general effect.  
Purpose  
An import health standard specifies the requirements for importing risk goods into New Zealand from all 
countries. This import health standard specifies  the requirements that must be met when impo rting Citrus 
plants for planting into New Zealand.  
Background 
An import health standard issued under the New Zealand Biosecurity Act 1993 (the Act) specifies the 
requirements to be met to effectively manage biosecurity risks associated with importing risk goods, including 
the risks from incidentally imported new organisms. I mport health stan dards  include measures that must be 
applied in the exporting country before the risk goods are exported. I mport health standards  also include 
requirements that must be met by importers during importation, including while the risk goods are in transit to 
New Zealand and held in a transitional facility, before biosecurity clearance can be given.  
Post-clearance conditions may also be specified in an import health standard . 
Who should read this? 
This import health standard should be read by  anyone involved in the process of importing Citrus  plants for 
planting into New Zealand (or who has an interest in  importing Citrus plants for planting).  
Why is this important? 
It is the responsibility of the importer to ensure that risk goods (i.e. Citrus plants for planting) comply with the 
requirements of the relevant import health standard. Risk goods that do not comply with the requirements of 
an import health standard may not be cleared for entry into New Zealand and may be directed for treatment, 
re-export, 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 weed seeds are intercepted on the consignment.  
Importers are liable for all associated expenses . 
Equivalence 
A chief technical officer  may consider an application for an equivalent phytosanitary measure to be approved, 
different from that provided for in this import health standard, to maintain at least the same level of protection 
assured by the current measures.  
Equivalence will be considered with reference to the International Standard for Phytosanitary Measures 
ISPM  24. Guidelines for the determination and recognition of equivalence  of phytosanitary measures . Import Health Standard : Citrus Plants for Planting

(such as drip irrigation). Overhead irrigation must not be used.  
d) Irrigation water must be collected and either allowed to evaporate or treated prior to disposal . 
e) Any debris on the greenhouse floor must be swept up or vacuumed (and disposed of in the 
normal qua rantine waste stream) rather than being hosed into the drain.  
 
Guidance  
• The transitional arrangements in regards to Parts 2.4.1  and 2.4(2)a)  are intended to allow existing 
quarantine greenhouses sufficient time to  make any changes that are needed to allow a facility 
operator to apply all post -entry quarantine requirements set out in those Parts.  
• Consignments imported before the end of the transitional period (i.e. before 23 January 2025) must 
either  comply with all  requirements set out in Parts 2.4.1 and 2.4(2)a)  of this IHS, or alternatively  
comply with additional requirements set out in Part 1.7 Transitional arrangements  before they can 
receive a biosecurity clearance . Consignments that comply with Part 1.7 Transitional arrangements  do 
not need to comply with requirements set out in Parts 2.4.1 and 2.4(2)a)  of this IHS.  
• After 23 January 2025,  the transitional arrangements will be removed from this IHS. All consignments 
imported after that date will need to meet all requirements of Parts 2.4.1  and 2.4(2)a) .

Part 2:  Specific requirements 
(1) All cuttings must meet all requirements described in Part  2.1 Leafless budwood/ cuttings . 
(2) All plants in vitro must meet all requirements described in Part  2.2 Plants in vitro.  
(3) All Citrus plants for planting must be screened in New Zealand for each regulated pest listed in  
Schedule 1 : Regulated pest list , as described in Part  2.3 Screening for regulated pests , unless: 
a) phytosanitary measures in relation to a regulated pest have been applied in accordance with an 
agreed Export Plan or at an MPI-approved offshore facility. In this case, the import permit will 
identify the regulated pests for which phytosanitary measures must be applied on arrival in New 
Zealand.  
(4) All Citrus plants for planting that require phytosanitary measures to be applied on arrival in 
New Zealand must be held in a transitional facility approved to the MPI Facility Standard: Post Entry 
Quarantine for Plants  as described in Part  2.4 Post-entry quarantine.  
2.1 Leafless budwood/cuttings  
(1) Prior to e xport, all cuttings must be:  
a) free from soil and other regulated articles ; 
b) clearly labelled with the full botanical name (genus and species) of all plants ; 
c) treated for insects and mites using either one of the treatment options listed in Schedule 3: 
Approved insecticide treatments for Citrus cuttings  and Schedule 4: Approved miticide treatments 
for Citrus  cuttings , respectively,  or alternative treatments that have been approved by MPI.   
d) held in a manner to prevent recontamination after insect and mite treat ments have been applied;  
e) shipped in packaging that:  
(i) is clean and free from soil, visible regulated pests and other regulated articles ;  
(ii) prevents the plant material from becoming contaminated with regulated pests or other 
regulated articles  during transit ; and 
f) accompanied by a phytosanitary certificate as described in Part  3.3 Phytosanitary certification.  
2.2 Plants in vitro (formerly tissue culture)  
(1) Prior to export, all plants in vitro must be:  
a) clearly labelled with the full botanical name (genus and species) of all plants;  
b) derived from aerial plant parts ; 
c) grown in a pest -proof and transparent vessel ; 
d) grown in a medium free from fungicides, antibiotics , and charcoal ; 
e) grown in the vessel in which they will be exported for at least 14 days prior t o shipment ; 
f) free from visible fungal or bacterial contamination; and  
g) accompanied by a phytosanitary certificate,  as described in Part  3.3 Phytosanitary  certification.  
2.3 Screening for regulated pests 
(1) To ensure freedom  from regulated pests , all Citrus  plants for planting must be screened for each 
regulated pest listed in Schedule 1 : Regulated pest list  on arrival in New Zealand , as described in this 
Part, unless:  
a) phytosanitary measures for a particular pest have been applied as described under an agreed 
Export Plan or at an MPI-approved offshore facility.  In this case, the import permit will identify the 
requirements of this Part that must be applied on arrival in New Zealand.  Import Health Standard : Citrus Plants for Planting   
  16 October 2023 
Ministry for Pr imary Industri es  Page 10 of 31 
Guidance  
• Specific environmental conditions are required to increase the likelihood of detecting regulated pests 
listed in  Schedule 1 : Regulated pest list . 
• As noted in Part  1.7 Transitional arrangements , a transitional period applies with regar ds to 
temperature regimes and quarantine requirements set out in Parts 2.4.1 and 2.4(2)a) . The transitional 
period applies only to plants imported from an MPI -approved offshore facility . Any consignments 
imported from an MPI -approved offshore facility  prior to 23 January 2025  do not need to comply with 
these requirements. Consignments that do not comply must meet all requirements set out in Part  1.7 
Transitional arrangements . 
2.3.1 Testing for regulated pests  
(1) All testing for regulated pests must be done at a transitional facility a pproved to MPI Standard 
155.04.03: Standard for Transitional Facilities for the Identification of Organisms . 
2.3.1.1   Reporting pest and disease symptoms 
(1) When a pest is found, or signs or symptoms of a pest are observed on a Citr us plant for planting by the 
facility operator, the facility operator must inform the MPI inspector  within 24 hours of detection.  
 
Guidance  
• Diagnostic testing may be undertaken when symptoms are reported to the MPI inspector to verify the regulatory status of the organism causing the symptoms.  
• Depending on the type of symptoms, samples may be tested for the presence of various classes of disease organism, including bacteria, fungi, nematodes, oomycetes, phytoplasmas, viroids and 
viruses.  
• The exact diagnostic tests that will be done will be decided by the MPI i nspector and staff at the 
diagnostic facility. This will depend on the type of disease symptoms that are present.  
• The MPI Facility Standard: Post Entry Quarantine for Plants  outlines the procedures  when any pests or 
disease symptoms are observed by the facility operator .  
• All diagnostic test ing will be done at the importer ’s expense . 
2.3.1.2   Mandatory testing  
(1) All Citrus plants for planting must be tested for all regulated pests identified in Schedule 2: Inspections 
and mandatory testing requirements , regardless of whether a plant is showing signs or symptoms of 
pests or disease (mandatory test).  
(2) Samples for a mandatory test must be collected during the first and second growing seasons, and/or 
(for cutti ngs) on first arrival in New Zealand, according to the timetables in Schedule 2: Inspections and 
mandatory testing requirements . 
(3) Each Citrus plant in a quarant ine greenhouse, or cutting on first arrival in New Zealand, must be 
individually labelled and tested, with the following exception:  
a) For PCR testing, samples taken from up to five plants of the same species can be combined to 
form a single composite sample for mandatory testing.  
 
Guidance  
• Mandatory testing is targeted testing that must be done for specified regulated pests (identified in 
Schedule 2 : Inspections and mandatory testing requirements  of the IHS), regardless of whether the 
plant is showing signs or symptoms of pests or disease.  
• Mandatory testing is required in addition to growing season inspection to provide additional assurance that a consignment is free from specified high- risk regulated pests. Mandatory testing may also be 
required when there is evidence that using growing season inspection under conditions described in Import Health Standard : Citrus Plants for Planting   
  16 October 2023 
Ministry for Pr imary Industri es  Page 11 of 31 
this IHS as the sole method for disease screening may not effecti vely manage the risk. For example , 
this may apply when it is known that a particular regulated pest has a prolonged latent period, meaning 
that infected plants are unlikely to show symptoms in post -entry quarantine.  
• All mandatory testing will be done at th e importer ’s expense.  
• When mandatory testing is required on first arrival in New Zealand, the import permit will specify the 
diagnostic facility to which the cuttings must be directed. As soon as the diagnostic facility has 
collected samples for testing, t he imported plants may be directed to the post -entry quarantine facility 
identified on the import permit .  
2.3.2 Inspection  
(1) All plants must be inspected for signs and symptoms of regulated pests by the facility operator at least 
twice per week during periods of  active growth.   
(2) All plants must be inspected for signs and symptoms of regulated pests by the MPI  inspector according 
to Schedule 2 : Inspections and mandator y testing requirements .  
 
Guidance  
• The first inspection by an MPI i nspector will not be completed until quarantine greenhouse plants are in 
a state of active growth.  
• In cases where some plants, or some individual buds on plants grafted with buds taken from  imported 
cuttings, do not enter a state of active growth in the first (or a subsequent) growing season, this should 
be discussed with the MPI in spector in regards to the growth status of each plant.  
• More information about plant inspections by the facilit y operator is included in the MPI Facility 
Standard: Post Entry Quarantine for Plants . 
• All inspections by the MPI inspector will be done at the importer ’s expense . 
2.4 Post -entry quarantine  
(1) For all Citrus  plants for planting, all requirements must be applied as described in this Part, unless:  
a) phytosanitary measures for a particular pest have been applied as described under an agreed 
Export Plan or at an offshore facility. In this case, the import permit will identify the requirements 
of this Part that must be applied on arrival in New Zealand.  
(2) Citrus  plants for planting must be quarantined in a transitional facility approved to the MPI Facility 
Standard: Post Entry Quarantine for Plants . The type and level of transitional facility will be specified 
on the import permit , unless:  
a) plants are imported under Part 1.6.2 of this IHS (from an MPI -approved offshore facility), in which 
case , the minimum period of post -entry quarantine will be eight  months  (240 days ) in a Level 3A 
quarantine greenhouse; or  
b) plants are imported under Part 1.6.3 of this IHS, in which case,  the minimum period of post -entry 
quarantine will be 1 7 months  (510 days ) in a Level 3B quarantine greenhouse.  
(3) The post -entry quarantine period for Citrus plants for planting begins after imported plants held in a 
quarantine greenhouse have started active growth.  
a) For plants derived from imported cuttings, active growth begins when all buds  grafted from the 
imported cuttings have developed fully expanded leaves . 
b) For plants imported as plants in vitro, active growth begins after the plants have been deflasked 
into a quarantine greenhouse.  
(4) For plants imported under Part 1.6.2 of this IHS (from an MPI -approved offshore facility), the post -entry 
quarantine period must be a minimum of one growing season of at least  eight  months  (240 days ) as 
per the spring and summer of the first growing season (Part 2.4.1).  Import Health Standard : Citrus Plants for Planting   
  16 October 2023 
Ministry for Pr imary Industri es  Page 12 of 31 
(5) For plants imported under Part 1.6.3 of this IHS, the post -entry quarantine period must be a minimum 
of 17 months  (510 days ). This must include two distinct growing seasons, with the first season at least 
10 months ( 300 days) long and the second season at least seven months  (210 days ) long.  
 
Guidance  
• For any Citrus plants for planting imported under Part 1.6.1  of this IHS (i.e. under an Export Plan ), the 
level of quarantine greenhouse and the length of th e post -entry quarantine period will depend on the 
specific regulated pests for which phytosanitary measures have been applied prior to export. This will 
be different for each Export Plan. The Director -General will identify the level of the quarantine 
greenhouse and the length of the post -entry quarantine period on the import permit. This information 
will also be made available on the MPI website at the time an Export Plan  is approved by a chief 
technical officer . 
• For any Citrus plants for planting imported under Part 1.6.2 of this IHS, the transitional arrangements 
identified in Part 1.7 Transitional arrangement  will apply unless plants are imported int o a Level 3A 
quarantine greenhouse and plants also comply with all requirements of Part 2.4.1 of this IHS. 
Transitional arrangements apply only to plants imported before 23 January 2025.  
• For any Citrus plants for planting imported under Part 1.6.3  of this IHS (i.e. from a source that is not 
approved by MPI), the import permit may give the option for plants to be transferred to a Level 3A 
quarantine greenhouse for the second growing season (after a minimum of 10 months in a Level 3B 
quarantine greenhouse). Transfer to a Level 3A quarantine greenhouse will only be considered if all 
mandatory testing required in the first growing season has been completed , with negative test results 
returned or, where positive test results are returned,  provided that the plants were subsequently 
effectively treated for any regulated pests detected during the first growing season. For all plants 
imported under Part 1.6.3 , the import permit will specify that the total post -entry quarantine period will 
be a minimum of 1 7 months.  
• 17 months is the minimum period a Citrus  plant for planting imported under Part 1.6.3  of this IHS must 
be in quarantine. Eight  months is the minimum period a Citrus  plant for planting imported under Part 
1.6.2  of this IHS must be in quarantine . A Citrus  plant for planting may be in quarantine for longer than 
the periods indicated above , especially if the plant does not meet the requirements of this IHS. For 
example, a Citrus  plant may be in quarantine for longer if the material is slow -growing, if pests or 
disease are detected, or if additional testing or treatment is required. MPI inspectors are responsible 
for determining when biosecurity clearance is given.  
(6) All cuttings must be dipped in 1% sodium hypochlorite for a minimum of 2 minutes on arrival at the quarantine greenhouse.  
(7) If plants in vitro  are subcultured in a quarantine tissue culture laboratory before they are transferred to 
a quarantine greenhouse, the following requirements must be met:  
a) At least one subculture from each imported plant must be developed to the stage where it can be 
deflasked into the quarantine greenhouse and screened for regulated pests as described in Part  
2.3 Screening for regulated pests : 
(i) This subculture should be taken during the first round of multiplication after plants arrive in 
New Zealand.  
(ii) If only one plant is obtained during the first round of multiplication, further rounds of 
multiplication may be undertaken. In this case, a subculture for transfer to the quarantine 
greenhouse must be taken from the first round of multiplication where more than one plant 
is obtained.  
b) Surplus subculture s that are produced as described in clause (7)a)  above may be retained at a 
Level 3 quarantine tissue culture laboratory throughout the post -entry quarantine period:  
(i) These plants may be subcultured and multiplied during the post -entry quarantine period .

Guidance  
• The operator of the post -entry quarantine transitional facility should ensure that an MPI inspector is 
notified:  
− when plants enter a quarantine greenhouse ; 
− when plants start active growth at the start of both the first and second growing season;  and 
− before the environmental condit ions described in Part 2.4.1 are applied.  
• If the MPI inspector is not notified,  this may lead to delays in the inspector doing growing season 
inspect ions and/or collecting samples for mandatory testing. This could result in delays to plants being 
cleared.  
2.4.1 Environmental conditions in post -entry quarantine  
(1) Specific environmental conditions must be applied as follows:  
a) Plants must be held in a  continuous 120- day (four -month) period of spring -like conditions in the 
first growing season  and 90-day ( three- month) in the second growing season . The daytime 
temperature must be 19 °C (± 3 °C) and the night -time temperature must be 1 7°C (± 3°C). 
b) Plants must be held in a continuous 120- day (four -month) period of summer -like conditions in the 
first and second  growing season s. The daytime temperature must be 2 3°C (± 3 °C) and the 
night -time temperature must be 20°C (± 3 °C). During the 120-day period of summer -like 
conditions, there must also be a continuous 30- day period where plants are held at 29°C (± 3 °C) 
during the day and a night -time temperature of 23 °C (± 3 °C). 
c) Plants must be held in a continuous 60 -day (two- month) period of autumn -like conditio ns for at 
least the first growi ng season with a temperature (day and night) of 1 6°C (± 3 °C). 
(2) If there are deviations from the requirements in clauses 2.4.1(1) while plants are being held in post -
entry quarantine at a transitional facility (i.e. in a quarantine greenhouse), the facility operator must 
inform the MPI inspector as soon as practical.  
(3) The operating manual for the quarantine greenhouse must describe how the environmental conditions 
given above will be monitored, maintained, and recorded.

*See the ABTRT for more details  
 
Guidance:  
• While a number of combinations of time and initial concentration may be used 
to achieve the minimum requirements (CT and minimum final concentration 
(g/m3)) of the treatment, care must be taken to avoid phytotoxicity. Phytotoxic 
effects of the treatment may increase when a higher initial concentration at lower temperature and reduced duration is used.  
• It is the importers responsibility to choose which ‘duration of treatment (time 
(h))’ option will be undertaken.  
• The importer undertakes treatments at their own risk (see legal disclaimer in 
Approved Biosecurity Treatments (ABTRT))  
 
The concentration -time product (CT) utilized for methyl bromide treatment in this 
standard is the sum of the fumigant concentration readings (g/m3) over time (h). This is 
in accordance with ISPM 43: Requirements for the use of fumigation as a phytosanitary 
measure .  
 
Hot water treatment 
followed by chemical 
treatment  
(Option 2) All treatments must be applied in the following order:  
1) Immersion in water at a minimum continuous temperature of 24°C for a 
minimum period of 2 hours;  
2) Immersion in water at a minimum continuous temperature of 45°C for a 
minimum period of 3 hours;  
3) Dipping (with agitation) for a minimum of two minutes in chlor pyrifos dip (2.4 g 
active ingredient per litre, or label rates) containing a non -ionic surfactant. If 
bubbles are present on the plant surface after the initial two-minute  period, 
the immersion period must be extended to a minimum of five minutes.  Import Health Standard : Citrus Plants for Planting
