Police are investigating after two people in Auckland say they found pills in their McDonald's sundaes.
The pair bought the icecreams at a West Auckland McDonalds store last night.
They went to hospital to be assessed and police said they were still trying to establish what the pills were.
A McDonald's spokesman said the store was cooperating with the police and had stripped back the icecream machine to demonstrate how it worked.
The store had given CCTV footage to police, the spokesman said.
