Prime Minister John Key is not smiling at a baby formula maker that is using a picture of him to promote its product.
"It's just against the cabinet rules," Mr Key said on Newstalk ZB on Monday.
The Herald on Sunday reported that Mr Key's office will ask Auckland milk powder manufacturer Cowala to remove a picture of the prime minister from advertising its powdered milk products.
Mr Key said on Monday that people could take photographs of him but they could not use them to endorse products.
The image was taken when Mr Key attended the opening of Cowala's Auckland factory in June.
