Police are searching for a pitbull cross dog after it bit two men and boy at a park on Auckland's North Shore.
Two men were bitten within an hour on Monday, after leaving the men's toilets at Bayswater Park.
The dog then went on to bite an eight-year-old boy who was playing with friends. An ambulance was called because he received a deep bite to his calf.
All three attacks happened in the toilet area next to the children's playground.
Police and animal control officers spent most of Monday and Tuesday morning searching for the dog, which is thought to be two to three years old, after it ran into a large cemetery.
They believe the dog may have been abandoned. They are warning people to stay away from the dog, which is tan with a cream chest and cream markings on its head.
