The fire in bushland around Drake has been the most destructive, burning through more than 60,000 hectares and 16 properties since it started almost two weeks ago.

Thirty-four homes have been destroyed - 26 of those by the most recent fires - and another 13 have been damaged.

Rural Fire Service Inspector Ben Shepherd said more than 40 fires were burning across the state on Tuesday morning and about a dozen of them were uncontained.

"It is important not to lose sight of the fact that, although these losses are tragic, there have been more than 600 homes that have actually been saved due to the great work of firefighters," he said.

Although rain and snow fell in other parts of NSW as conditions eased overnight, Mr Shepherd said firefighters were concerned more blazes would be sparked by dry lightning expected on Tuesday afternoon.

NSW Rural Fire Service Deputy Commissioner Rob Rogers told Seven's Sunrise program the rain falling on the state's coast, desperately needed to extinguish the fires, had not extended inland.

"The sheer size of these fires are going to make them a long-term proposition to try and contain and there are no easy answers to getting this fires out," he said.

Three fires remain at Advice level: the Long Gully Rd bushfire near Drake, the Bees Nest fire near Armidale and the out-of-control Kingsgate fire near Glen Innes.

The Kingsgate fire has burned through more than 16,000 hectares but the threat to homes has eased.
