Fortification of flour with the B vitamin folic acid
All non-organic wheat flour used for making bread must be fortified with the B vitamin, folic acid, by mid-2023.
8 JULY 2021: Changes to Folic Acid Fortification
The Government announced its decision to mandate the fortification of folic acid in non-organic wheat flour used for bread making.
This decision aims to improve health outcomes and health equity, while considering cost-effectiveness and consumer choice. There is a 2-year transition period for existing flour millers to make the necessary changes, ending mid-2023.

Adding folic acid to bread-making flour
By mid-2023, flour millers must comply with Standard 2.1.1 – 5 (a) Cereal and Cereal Products of the Australia New Zealand Food Standards Code, which outlines that non-organic wheat flour that is sold as suitable for making bread must contain no less than 2mg/kg, and no more than 3mg/kg of folic acid.

New Zealand Food Safety will be working with industry to develop resources and guidance to assist flour millers with understanding and meeting the requirements of this Standard.
Adding folic acid to bread
In 2014, the New Zealand Association of Bakers agreed to fortify 25% to 50% of bread with folic acid through a Code of Practice. The Code of Practice for Voluntary Folic Acid Fortification of Bread will no longer be valid once fortification of folic acid becomes mandatory, as the New Zealand (Permitted Fortification of Folic Acid in Bread) Food Standard will be revoked at the end of the two-year transition period.
During this transition period, bread that is fortified with folic acid must meet the requirements set out in the New Zealand (Permitted Fortification of Folic Acid in Bread) Food Standard 2012. This means that until flour millers begin mandatory folic acid fortification, bread makers may fortify bread with folic acid.

Guide to adding folic acid to bread
We have a guide to adding folic acid to bread for bakers, retailers, and food safety officers. It will help you interpret and apply the voluntary standard. This guide can be followed until mandatory folic acid fortification is implemented. After this date, this guidance will no longer be valid.
