Fighting fires in the Far North - most started by arsonists - has cost more than $1 million this summer.
With at least two months to go before the fire risk starts falling, the Northern Rural Fire Authority is warning the cost is likely to rise.
Principal rural fire officer Myles Taylor said 2011-12 was shaping up to be another expensive fire season, approaching the $1.6 million bill racked up in the drought-hit 2009-10 season and bringing the cost of fighting Northland's rural fires in the past five years to more than $7 million.
The most expensive fire this season was a roadside scrub fire which spread into a pine plantation near Horeke, South Hokianga, destroying about 345ha of forest and costing $856,000 to put out.
Earlier fires at Ahipara and Maitai Bay cost $80,000 and $114,000, respectively, to extinguish.
