Maximum Residue Levels (MRLs) for Agricultural Compounds
Here you will find information on meeting MRL requirements.
Requirements for food sold in New Zealand
All imported and domestically-produced food sold in New Zealand (except for food imported from Australia) must comply with the current Food Notice: Maximum Residue Levels for Agricultural Compounds and amendments.
The MRL Notice lists the MRLs for a range of agricultural compounds, but also includes a provision for residues of up to 0.1 mg/kg for agricultural compound/food combinations not specifically listed. In addition, the MRL Notice recognises the role of Codex standards for imported food.
Under the MRL Notice, agricultural compound residues in food must:
- comply with the specific MRLs listed in the MRL Notice (including the ‘default’ MRL of 0.1 mg/kg where no specific MRL is listed), or
- if the food is imported, comply with Codex MRLs and where no Codex MRL applies,complywith the MRLs listed in the MRL Notice (including the ‘default’ MRL of 0.1 mg/kg where no specific MRL is listed)

Food imported from or exported to Australia
Under the Trans-Tasman Mutual Recognition Arrangement (TTMRA), food imported from Australia may be legally sold in New Zealand, so long as it complies with Australian requirements. The converse is also true, so food imported from New Zealand into Australia is legal, so long as it complies with New Zealand requirements.
Therefore, in addition to the options above, food imported from Australia may also comply with Standard 1.4.2 of the Australia New Zealand Food Standards Code, and New Zealand food exported to Australia may comply with the MRL Notice (link above).

Requirements for New Zealand primary produce
Food produced under the Animal Products Act must also comply with requirements under the Animal Products Act 1999. See the Animal Products section of the website for more information.
Dairy producers operating under Risk Management Programmes must also comply with dairy standards. Check the dairy sector of this website for more information on residues.
MPI also maintains a database to provide exporters with information on pesticide MRLs established by New Zealand’s major trading partners.
An international MRL database is available by subscription.

Requesting the establishment of an MRL
The majority of requests to establish an MRL for an agricultural compound are made in association with an application for registration (or variation to a registration) under the Agricultural Compounds and Veterinary Medicines (ACVM) Act. The requirement for a new or amended MRL will be considered by the Approvals & ACVM Group as part of the appraisal of trade name product registration.
If a person or organisation requests establishment of a MRL not associated with an application under the ACVM Act (for example, an importer of food commodity into New Zealand), then they should contact the Approvals & ACVM Group (firstname.lastname@example.org) for details. MPI will require information (including relevant data sets) to confirm the residues in the food commodity, that the use is appropriate, and the toxicological end point (such as the Acceptable Daily Intake and/or the acute Reference Dose).
