Today's incident is the second water incident in the district in as many days.
A 10-year-old girl remains in Whakatāne Hospital today after an incident at the Whakatāne Aquatic and Fitness Centre yesterday.
A Bay of Plenty District Health Board spokeswoman said the girl was in a stable condition in acute care at Whakatāne Hospital.
The girl was rescued by aquatic centre staff following the incident last night, a Whakatāne District Council spokeswoman said.
A St John spokeswoman said the service was notified of the incident about 4.59pm yesterday and one patient was treated on site before being taken to Whakatāne Hospital in a serious condition.
