Whanganui Hospital's Newcombe Ward will have its 80th anniversary this Friday.
The Whanganui District Health Board said the building officially opened on August 18, 1938, by then chairman Mr W.E. Broderick.
To mark the occasion, hospital staff will unveil a display board in the foyer of Te Kopae - the ward's name today - setting out its history.
The ward was named after Wanganui Hospital board member Miss Mildred Newcombe who died on September 20, 1938, a month after the opening.
It was a new isolation ward at the time and replaced the infectious diseases block, which was built hurriedly in 1919 to cope with the influenza epidemic.
