As somebody who's job in a former life was being responsible for compliance it's safe to say I had plenty of arguments with Foodstuffs about this.

In a nutshell it's pure laziness from Pak 'n Save. Nothing else. They don't want to bother maintaining ingredients and NIP for products so simply don't bother. As recipes are different between stores they are responsible for maintaining these so much of what was on the labelling was never 100% correct anyway.

There has long between debate over the interpretation of the law when it comes to things such as this I don't believe the wording of the law exempts the products, and it was certainly not the intention of ANZFA (before the FSANZ days) when the joint food standards to have such glaring exemptions. The sticker also verges on being illegal even if you are of the opinion pre-packaged bakery products are exempt from mandatory NIP and ingredients since it does not declare allergens on the label which is a basic requirement even on products where NIP and ingredients are not required.

The problem with the labelling laws since the day they came out is there is very little enforcement. It takes people to complain before things happen, and even then things don't necessarily happen. It's still not hard to find products sold in stores and supermarkets that don't even have basic things such as NZ contact details for a distributor on them, let alone ingredients and NIP data that meets FSANZ standards.
