Currently there are about 12 St John volunteers in the Mangawhai area. Mr Devanney said he hoped the station would raise St John's profile and double the volunteer numbers.
"It will make it easier for us to help out the community, because of our capacity ambulances aren't available 24/7 because our volunteers might be doing other things. Sometimes we need to get ambos from Maungaturoto."
Mr Devanney said currently all profits made from goods sold at the St John op-shop went to the station.
"The money is staying in the community and it will continue to stay that way."
There would be an open day at the station some time in August, he added.
