Dear K,
Thank you for your request, that was partially transferred from Minister Hoggard’s Office to
the Ministry for Primary Industries (MPI) on 22 October 2025, requesting information relating
to food waste in supermarkets. Your request has been considered under the Official
Information Act 1982 (OIA).
We understand the Office of Hon Andrew Hoggard wil be responding to the following parts of
your request:
•
I would like a breakdown of wasted foods at supermarkets.
•
Where does it go.
You requested the following:
•
What is the policy for shelf life.
Compositional and label ing requirements for food sold in New Zealand and Australia are
developed by Food Standards Australia New Zealand (FSANZ) and set in the Australia New
Zealand Food Standards Code (the Code) which you can view on the FSANZ website at
https://www.foodstandards.gov.au/food-standards-code. New Zealand is a partner to this joint food
safety system with Australia and has adopted the Code under the Food Act 2014. You can view
this at
https://www.legislation.govt.nz/act/public/2014/0032/latest/DLM2995811.html?src=qs. Food businesses are responsible for meeting the Code requirements in New Zealand. New
Zealand Food Safety, the business unit in MPI responsible for food safety and suitability, has
put in place a framework which ensures food businesses are meeting legislative
requirements, including the Code.
The Code outlines a range of requirements including requirements around date marking
(usually a ‘best-before date’ or ‘use-by date’). Use-by dates relate to food safety – food may
not be sold after its use-by date as it may no longer be safe to eat after this date. Best-before
dates relate to the quality of food. Food products can stil be sold after their best-before date
but may no longer be at their best (e.g. bread may be stale after its best-before date but
won’t make you sick).
The responsibility for establishing the correct type of date mark to use, and the appropriate
date to apply, falls on the manufacturer of the product. MPI has developed some guidance
on determining the shelf life for food products which can be found on MPI's website at
https://www.mpi.govt.nz/dmsdocument/12540/direct.

If a business chooses to extend the shelf life of their products to reduce food waste, they can
do so by submitting a date mark alteration application to MPI for assessment and approval.
The date mark alteration application form can be found on MPI’s website at
https://www.mpi.govt.nz/dmsdocument/61984-Date-Mark-Alteration-Application-Form-2016.
Under the Code, MPI has the delegation to grant permissions for date mark alterations
following the assessment of any safety risks.
Further information about date marks on food, including tips on how to prevent food waste
can be found on MPI’s website at
https://www.mpi.govt.nz/food-safety-home/reducing-food-
waste-at-home. Should you have any concerns with this response, I would encourage you to raise these with
the Ministry for Primary Industries at
[email address]. Alternatively, you
are advised of your right to also raise any concerns with the Office of the Ombudsman.
Contact details are: Office of the Ombudsman, PO Box 10152, Wellington 6143 or at
[email address]. Yours sincerely
Jenny Bishop
Director Food Risk Management
