More than $1 million was spent battling the Lake Pukaki fire in the Mackenzie Country.
The 12-day blaze, starting on August 30 last year, swept through almost 3500 hectares near Twizel.
At its peak, 150 firefighters worked to control it, along with 18 helicopters and two planes.
An Official Information Act request to Fire and Emergency NZ shows the bill for the fire was $1,116,759.
