The Lindfield Park Road fire that started more than six months ago is finally out.
Over 260mm of rain has fallen across the fire ground this past week.
The Rural Fire Service said an inspection done using thermal imaging cameras indicate the fire has been extinguished.
RFS Mid Coast district officer Stuart Robb said it was "great news".
"It is certainly a relief that a fairly long project we can now safely say is finished," he said.
"That wetland have a significant amount of water in the area, there is a lot of regrowth that has started and is returning to normal water levels."
The Lindfield Park Road fire, which began on July 18, had been active for the past 210 days and burnt over 400ha of peat under the surface.
The fire presented a number of challenges for fire fighters including close proximity to the Port Macquarie Airport, high density housing in the vicinity and the nature of the vegetation types.
Lindfield Park Road resident Daniel Coleman described the last six months as "terrible".
