Cup holders on trolleys at New World Tokoroa are "only to be used with 20 oz Coca-Cola products".

It took a Tokoroa supermarket owner five years to discover that cup holders installed on trolleys contain a warning that they should only be used for Coca-Cola products.

Cup holders on trolleys at Tokoroa New World read: "Use only with 20 oz Coca-Cola products, hot drinks may burn children. Beverage can openings may cut children's fingers. Open cups or cans may spill and cause falls."

Tokoroa resident Serena Waterworth told ONE News she was upset the cup holders seemed to be encouraging people to consume sugary drinks, which were a potential problem in the Waikato town.

Store owner Damon Jakemen, said he was completely unaware the cup holders on his trolleys had anything to do with Coca-Cola.

"That's no good. Only 30 of our 120 trolleys have cup holders, and they were put on for coffees," Jakemen said.

It would not be an issue to remove the 30 cup holders if people were upset about them, he said.

The cup holders arrived on the trolleys five years ago, and this was the first time Jakemen had been made aware of the imprinted words.

The words were more of a warning about being aware of hot drinks being near a toddler, he said.

It was disappointing the customer had not come and talked to him first, as he would have liked to hear her side of the story first.

"It's a bit embarrassing to know it's been on the news and no-one has bothered to contact me until now."

Representatives from Coca-Cola were unable to be contacted.
