Staff at Auckland Zoo and Kelly Tarlton's are hoping a trio of critically ill turtles they are treating make a full recovery.
The three reptiles - two hawksbills and one green sea turtle - are being cared for at the facilities after being found off Northland's west coast last month.
One of the hawksbill turtles, a 7-year-old male, is thought to have a eaten a piece of plastic that caused gut impaction.
All the turtles were found severely emaciated, dehydrated and suffering from bacterial infections. All were covered in barnacles and algae.
