Auckland Council is investigating reports of rodent infestation at a South Auckland McDonald's.
A diner at the Manurewa branch, on the corner of Great South and Weymouth Rds, filmed at least five mice running around the playground last Thursday.
The play area has been closed, but the restaurant remains open and is serving food to its customers.
Ashwin Rangarajan told the Herald he had taken his 3-year-old daughter for a Happy Meal at the fast-food outlet when he saw the rodents.
"After dinner, I went to the counter to ask why the playground was locked and they said it was because there was a mouse there.
