The museum was originally started by Capital Coast Health (now Capital and Coast District Health Board). In 1998 Capital Coast Health expressed their intention to relinquish the Museum as they planned new uses for the Porirua Hospital campus. As a result the Friends of Porirua Hospital Museum Inc society was formed as a supporters organisation for the Museum.

The museum is staffed and run by volunteer members of the society. We welcome anyone would like to join or volunteer.

In 2006, a Trust was formed to provide for fundraising and long term maintenance of the museum.
