6. Description of content:  An application (APP203974) for a reassessment under section 
63 and 63A of the HNSO Act.  
Hydrogen cyanamide is a plant -growth regulator used to promote 'bud -break' in the 
production of kiwifruit. It is also applied to a lesser extent for the same purpose in some 
apple, cherry, apricot, and kiwiberry crops.  
New information on the effects of hyd rogen cyanamide led to reassessment grounds being 
established under section 62 of the HSNO Act in September 2019. The new information 
included the human health and environmental risk assessments undertaken by the 
European Food Safety Authority (EFSA). The EFSA review, other assessments published 
by regulatory authorities in the United States (US) and the Europe Union (EU), and risk 
assessments provided by stakeholders, have been used to inform the EPA's current 
assessment of risks and benefits of hydrogen c yanamide use in New Zealand.  
Based on its preliminary assessment, the EPA is recommending that current approvals for 
hydrogen cyanamide be declined, and the substance no longer be approved. The EPA is 
proposing that hydrogen cyanamide be phased out over fi ve years, with tighter controls 
taking immediate effect after the final decision on the reassessment  
7. Objective and rationale, including the nature of urgent problems where 
applicable:  Protection of human health or safety; Protection of the environment  
8. Relevant documents:   
• General information regarding the EPA's reassessment of hydrogen cyanimide is 
available at the links below: https://www.epa.govt.nz/public -consultations/in -
progress/hydrogen -cyanamide -reassessment/  
• The related application documents listed above are available a t the following link:

register/view/APP203974  
9. Proposed date of adoption:  The hearing of the applic ation is scheduled to commence 
on 5 December 2022 and the EPA is required to publicly notify its decision not later than 
30 working days after the conclusion of the hearing. The decision is therefore likely to be 
notified in early 2023.  
The Decision -Making  Committee will determine the outcome of the reassessment 
including any entry into force dates.  
Proposed date of entry into force:  To be determined  
10. Final date for comments:  60 days from notification  G/TBT/N/NZL/112
