NZ Food & Grocery Council (FGC) chief executive Katherine Rich said the website will offer consumers greater protection in case a food product is found to be unsafe.
The more companies that join the new system, the more efficient and effective it will be, Rich added.
All the food companies have been encouraged to register with the website.
The new tool has been developed by standards organization GS1 NZ, in partnership with FGC, Foodstuffs, and Progressive Enterprises. It has been trialled by FGC members such as Nestle, Cadbury and DB Breweries.
