Hamilton company Bizline distributes the product. Business development manager Salman Abbas said the firm had stopped importing the confectionery in March and he did not see what all the fuss was about.
"They were one of our most popular products."
He said that with so many different types of confectionery on the market, companies had to try new packaging to stand out.
"They do ... look like Panadols," he said, "but there are so many other products on the market like this."
Mr Abbas said Choco 4 is sold in the United States, Britain and Australia, and when he spoke to the Pakistani manufacturers, Hilal Confectionary, last week, they said they had not had any complaints about their packaging.
Mr Abbas said Bizline stopped importing Choco 4 because the expiry dates were misprinted on the last shipment.
