Alderney will resume running its own ambulance service from 21 December.
The States of Alderney said it had assembled a new team of volunteers to take over a 24-hour service.
A dispute over the sacking of the Alderney Ambulance Service's chief officer led to a strike by the volunteer crews on 5 December.
The service was dissolved on 11 December and cover has been provided by Guernsey's St John Ambulance since the strike began.
All volunteers will have an "appropriate level of training" and will receive "technical and professional support" from St John, the States said.
The temporary service will work through co-operation between the The Island Medical Centre, the Mignot Memorial Hospital, St John Ambulance Guernsey, the States of Alderney Fire and Rescue Service and the Alderney Airport Fire Service.
The States of Alderney said it would continue work to "develop the right model" for a long term ambulance service, including engaging with the views of the local community in early 2020.
The dismissal of chief officer Melanie Walden followed a review into the service by Richard Webber, the Chief Paramedic St John Ambulance England.
Among Mr Webber's findings were lifesaving equipment that had not been serviced and "inadequate" patient assessments.
The States said: "All out-of-date, damaged or missing equipment has been removed or rectified."
