Tauranga Hospital celebrated its centenary along with its newest delivery yesterday.
A baby boy was born to Madeline Parker and Manuell Korzelius, but they hadn't decided on a name for him yesterday afternoon.
"We didn't know what he was going to be, so we had a few girl names and a few boy names, but none of the boy names we had really fitted," said Ms Parker.
"So we will go back to the drawing board."
The centenary baby was born at 04.50 am yesterday after a natural birth.
He will join brothers Riley, 10, Connor, 8, and Oliver, 6 and weighed eight ponds was 56 cm at birth.
Ms Parker said it was a long labour with "a few false starts" however they arrived at Tauranga Hospital for the real deal 10 pm Wednesday night.
"Monday and Tuesday night we were up all night."
Ms Parker said her son was due one week earlier and they had been booked in for a caesarean section late yesterday.
"We waited until the last possible day," she said.
Both baby and mum are healthy and well.
Ms Parker said she was born in the old maternity unit in the hospital at Tauranga Hospital along with two of her children.
Bay of Plenty District Health Board chief executive Phil Cammish said the hospital's birthday was a historic event to reflect on a "100 years of innovation and excellence".
When the hospital was first opened on March 6 1914 it consisted of a four-bed male ward and two-bed female ward.
It had four live-in staff, a cow for milk supply and a horse for staff transport.
"Today we have a modern hospital that can no longer be considered a cottage hospital," said Mr Cammish.
"I am often told by people how proud they are of Tauranga Hospital, and especially so when they drive past and compare today's modern buildings to the 1950's cottage hospital.
"Reflecting on the last 100 years has presented a timely opportunity for us to reconnect with the past, and discover stories about people who have worked at the hospital during that time," said Mr Cammish.
Minister of Health Tony Ryall will visit the hospital today (Friday) and unveil a plaque in the roof garden commemorating the centenary.
