If you are importing or manufacturing a pesticide, veterinary medicine, or other hazardous substance for use in New Zealand, you must ensure it's approved. If it's not, apply for approval here.
We recommended you contact one of our advisors as early as possible. We can help answer any questions you may have during the preparation of your application. Contact us by:
- phone (within New Zealand): 0800 2255 372 (0800 CALL EPA)
- email: HSapplications@epa.govt.nz
If your substance is already approved to be imported into or manufactured in New Zealand, or does not have hazardous properties, you do not need to apply for an approval.
Which application form to use depends on the type of substance you are applying for. You can say whether your substance is eligible for a rapid assessment, as per section 28A of the HSNO Act, on each of the forms.
- Hazardous substances (other than pesticides and veterinary medicines) application form (DOCX, 390KB)
- Veterinary medicine application form (DOCX, 406KB)
- Pesticide application form (DOCX, 418KB)
- Pesticide application guidance document (PDF, 938KB)
Please note pesticide applications made on the application form dated May 2015 are no longer accepted.
Include any confidential information at the same time as the application.
The application process
Once we have received your application, we will assess the pathway and determine if your substance is eligible for rapid assessment or will undergo a full assessment.
The length of time it takes to process an application depends on the type and complexity.
Supplying confidential or commercially sensitive information
We collect confidential or commercially sensitive information as part of our work to ensure hazardous substances are used safely and appropriately in New Zealand.
While we have a responsibility to you to store the confidential or commercially sensitive information you provide safely, we also have a responsibility to the general public.
If we receive a request under the Official Information Act 1982, generally, we must make it available unless there is a good reason to withhold that information which is not outweighed by the public interest.
Requests for further information
Requests for further information before public consultation. Sometimes we will request further information from an applicant or other sources before the application is publicly notified or, for application that are not consulted on, before the consideration date is set.
For publicly notified applications, the requested information is published online when public consultation starts.
If the applicant doesn't provide the information within a year, the application lapses.
Requests for further information from other sources
Sometimes after an application has been publicly notified or the consideration date set, we will seek further information from sources other than the applicant.
This information is published online at least 10 working days before a hearing or when the application is considered.
We have the power to postpone a hearing or consideration until further information of this type has been received. This is why time waivers are sometimes sought at the same time as further information requests.
Data requirements for assessments of active ingredients
When we, the EPA, assess a new hazardous substance for use in New Zealand, we need information. We need to know about the physical and chemical properties, toxicological effects, the environmental fate and the ecotoxicological effects of the substance to support the decision.
We use this information to consider the benefits of using the substance and we weigh these alongside the risks and the cost.
For more information about the approach we use for evaluating the risk, cost and benefit of a hazardous substance, including technical appendices about the modelling approach:
For chemical pesticides, the following document gives our data requirements in a checklist format (mandatory and conditional requirements):
Please contact us (at HSapplications@epa.govt.nz) to check the data requirements for applications for substances other than chemical pesticides (e.g. a new veterinary medicine, pure chemical, or biological pesticide).
While gathering data to support your application, remember that new studies may not be the only way of meeting the data requirements. In some cases it may be possible to justify waiving a specific data requirement or a read across from a similar substance(s).
However, if a type of information is required by us, and it is not available, you should explain why. If you consider that a study is not needed then you must include a justification for waiving this data requirement with your application.
If you are uncertain about what information is needed for your application, please get in touch by email:
Impurities of active ingredients
The active ingredients in pesticides can contain manufacturing impurities that show additional, or more severe, toxic and/or ecotoxic properties compared to the active ingredient.
Limits for these toxicologically relevant impurities have often been established by overseas organisations, such as the Australian Pesticides and Veterinary Medicines Authority (APVMA) and/or the Joint FAO/WHO Meeting on Pesticide Specifications (JMPS).
When toxicologically relevant impurities are identified for active ingredients in pesticides, a control may be applied to the substance to limit the amount of the impurity that may be present.
In most cases these limits will be in line with those established by the APVMA or JMPS. However, we may at times set limits for other toxicologically relevant impurities where this is considered appropriate.
Components of concern (excluding active ingredients)
Our risk assessment of pesticides is primarily based on an assessment of the risks from the active ingredient. However, frequently other components in a substance may also be of potential concern.
Examples include components classified as Carcinogenic, Mutagenic or Reproductive toxicants (referred to as ‘CMR substances’), or components which have been banned for use in pesticides overseas due to human health or environmental concerns.
Controls on these components
Such substances are often subject to restrictive regulations overseas, and we also place extra controls on them, because of the potential severity of the hazards they present. This is particularly the case when the substance is expected to have wide dispersive use or where the general public are likely to be exposed to the substance.
Reformulating the substance or adding additional controls, in some cases
In some cases this has led to recommendations that an applicant reformulates the substance to eliminate the component of concern, where this is achievable.
In other cases, additional controls have been applied to the substance to manage the potential adverse effects. We will contact applicants to discuss options with them when such situations arise.
In addition to CMR substances, we may also take action over components with other hazard classifications where there are concerns over their risks to human health or the environment.
Examples of components of concern include:
- Naphthalene (CAS 91-20-3) in hydrocarbon solvents (classified as a suspected human carcinogen, 6.7B)
- The solvent 1-methyl-2-Pyrrolidinone (NMP, CAS 872-50-4) (classified as a known or presumed reproductive toxicant, 6.8A)
- Nonylphenol ethoxylates (e.g. CAS 9016-45-9) (potential PBT (persistent/bioaccumulative/toxic) and endocrine disruptor).
In all these cases it is known that alternative substances are available that can be used in their place.
If you have an existing approval containing a non-active ingredient component that is a CMR, or otherwise of concern, and you are interested in reformulating to eliminate that component, then we would encourage you to contact an EPA Advisor to discuss the possibility of making an application.
