The spud - nicknamed as ‘Dug the Potato’ - weighs in at a whopping 7.9kg after it was discovered on a farm in Hamilton in New Zealand by Colin and Donna Craig-Brown while they cleaned their vegetable garden in August.

Colin told Stuff: “I said to Donna, ‘should we go for the Guinness World Record,” which is currently held by a tatty found in Nottinghamshire, to which Donna replied: “can you really be bothered?”

After jumping through all the hoops, they now need certification that Dug is indeed a potato.

Of the requirement, Colin said: ““Do they think I genetically modified it?” Colin said.

“It makes me feel s***, it’s been a roller-coaster of emotion.”

He continued: “While it’s extremely deflating, I want to prove them wrong. We will do everything they ask of us… so at the end of the day, they can say yes or no.”
