Pahiatua St John Ambulance service is operating out of the Woodville St John Ambulance Station temporarily due to problems with the building in Pahiatua.
St John had a review done on the Pahiatua site.
"It was deemed unfit for our team to work out of due to mould and leaking," said Steve Yanko, District Operations Manager Central South District.
"St John is looking at repairs to the current site however the safety of our teams is paramount therefore moving the base to our Woodville site will occur until the matter is resolved.
