The Fire Service says proposed changes to its regional management structure will not affect day-to-day fire fighting.
The organisation plans to reorganise its firefighting regions from eight to five but says this won't affect the number of firefighters or stations.
National Commander Mike Hall says initial restructuring began two years ago when the country was divided into 25 areas.
Mr Hall says the new structure will begin operating in July following a period of consultation.
He says there will be no job losses as a result of the restructuring.
