CEO Dr Steven Yennie said the hospital needs to get its administration, facility and equipment in order.
However, the most immediate need now is space, he said.
The hospital, located in the Port Moresby North-West electorate, serves people from all over the National Capital District.
It receives more than a hundred people a day.
“Spacing is a big issue we have here. We really need to improvise with the critical care service,” he said.
The hospital at the moment does not have an intensive care unit and a high dependency ward to care for their critically ill.
These cases are usually referred to the Port Moresby General Hospital once they are stabilised.
There is a plan in place to expand wards and build a high dependency unit.
CEO Yennie said the hospital needs to re-organise properly, taking into consideration the major clinical division with priority given to the emergency division, consultation clinics, outpatient, wards and theatre.
He is using the media as a platform to advocate for corporate companies and other stakeholders to see the need of Gerehu Hospital.
“The appeal is open. Opportunity is there for them to come and help us so we can improve our facility, equipment, staff,” he said.
