Daisy the Great White shark's tracker has ended up on dry land - and her whereabouts are unknown.
Daisy shot to fame this year, when the data on her movements was made public for all to view.
She lost her tracker three days ago near Matakana Island, and it later washed up in Tauranga.
Data shows it's been picked up and taken to central Gate Pa.
Marine biologist Dr Riley Elliot is asking for it to be returned. He says it looks like a mini blimp, and is the size of a beer can.
"It's got an aerial on it, it's got a steel tracer on it that goes to a little metal dart- it'll be covered in algae and seaweed and barnacles, potentially."
