Information for suppliers
As the grocery industry regulator, our role includes monitoring competition and efficiency in the grocery industry, promoting transparency, carrying out reviews, inquiries and studies, making information available and enforcing the law.
Rules and Regulation
Under the Grocery Industry Competition Act we have specific responsibilities for the Grocery Supply Code. The Code is a set of rules for the conduct of regulated grocery retailers (RGRs) Foodstuffs North Island, Foodstuffs South Island and Woolworths New Zealand when dealing with their grocery suppliers.
Further information on the Grocery Supply Code can be found on our website.
The Grocery Industry Competition Act also contains a set of provisions that seek to enable cost-effective wholesale supply of groceries to promote competition and efficiency in the grocery industry, including requirements on RGRs to provide wholesale offerings.
We currently have an Inquiry in progress into the wholesale supply of groceries to consider whether additional regulation should apply.
Further information about the Wholesale Supply Inquiry and the wholesale regulatory regime can be found on our website.
Our broader regulatory role also means that we oversee the Commerce Act and the Fair Trading Act, which cover all businesses in New Zealand including grocery suppliers and retailers.
We encourage you to get in touch to share your experiences in the grocery industry through our grocery supplier surveys. You can also contact our team at grocery.regulation@comcom.govt.nz or submit an anonymous reportopen_in_new at any time.
Grocery Supplier Survey
The grocery supplier survey is a tool we use to understand supplier insights into the grocery sector. Feedback from suppliers in our 2024 survey fed into the Supplier Survey report and helped us to better understand relationships in the sector and identify issues we need to focus on.
If you would like to be kept updated on survey work undertaken by the Grocery Regulation team, subscribe to our email list.
We are planning to undertake further surveys in the future for both monitoring and to seek views on specific issues. We welcome feedback that can help us to improve your experience and support participation.
If you have any questions or concerns, please contact us by emailing grocery.regulation@comcom.govt.nz
2026 Grocery Supply Survey now live
We are currently seeking feedback from grocery suppliers through an anonymous online survey.
This will be the second time we have sought feedback in this way.
Supplier feedback this year will help us to understand what has changed since 2024 and how suppliers feel today.
Suppliers can submit responses any time before Tuesday 17 March.
The survey is designed to be anonymous by default, so responses cannot be connected to you or your organisation by retailers or the Commerce Commission. To provide us with some context for the responses that we do receive, we have asked some additional questions about what you supply, who you supply to and the size of your business. This information is helpful to us, but you can skip any question in the survey if you are not comfortable with answering it.
We understand suppliers may still have concerns about completing it. If you want to provide feedback, but have concerns about participating in the survey, you can email us directly on grocery.regulation@comcom.govt.nz or by using our Anonymous Reporting Toolopen_in_new.
Please contact us if you have any questions or concerns.
Grocery Supplier Survey 2024
In November 2024, the Commerce Commission undertook an anonymous survey in partnership with the research agency TRA. The survey aimed to gain more understanding of grocery suppliers, the environment they operate within, the impact of the Grocery Supply Code and their experience supplying wholesale groceries.
An aggregated report prepared by TRA can be found below. Additionally, the insights gained from responses have helped the Commission in its projects such as the review of the Grocery Supply Code.
Resolve a dispute
A dispute resolution scheme has been set up to help resolve disputes between grocery suppliers, wholesale customers and regulated grocery retailers. The scheme is an out-of-court process set up under the Grocery Industry Competition Act 2023 and designed to quickly and fairly resolve disputes about the supply of groceries.
The scheme is operated by the New Zealand Dispute Resolution Centre. For more information, please visit www.grocerydispute.co.nzopen_in_new.
Submit an anonymous report
We recognise there are situations where someone who has knowledge or specific information about the conduct of a grocery industry participant (e.g., a regulated grocery retailer, supplier, or other retailer) and might be reluctant to report it for fear of negative consequences or reprisals (such as being delisted from a retail store).
The Commerce Commission’s Anonymous Reporting Tool provides a secure channel to be able to report information without disclosing your personal information.
