The baby was taken to hospital for a precautionary check-up after being immediately reunited with its parents.
Police said they have still not found the offender responsible, however, inquiries are ongoing.
Only yesterday, another baby was lost in West Auckland.
Two-year-old Willow escaped out of an unlocked gate at the family’s home on Zodiac St, Henderson about 2pm.
Hundreds of concerned West Auckland residents joined police Search and Rescue during a six-hour search for the girl.
It had been an agonising wait for Willow’s loved ones as the community searched for the missing child.
Willow’s mum understood a woman had found Willow on Universal Drive and taken her home to play with the woman’s grandchildren.
