Whakatāne Hospital emergency department (ED) has seen sudden spikes in patient numbers with multiple 100-plus days in recent weeks.
"We've had some significant spikes in attendances recently where we have experienced a number of days around the 100-patient mark," ED clinical lead Tamsin Davies said.
The average daily figure in 2018 was 60.
Davies sent out a renewed call for those who did not need emergency treatment to keep the department for those who did.
