Featherston fire chief Colin Farmer faces big bill over fire McKenna said the second blaze was quickly doused and had involved an area measuring about 50m by 110m and was "perhaps started by a discarded cigarette".
Mr Wishnowsky said the larger blaze had been brought under control and the landowner was left to dampen down any hotspots.
He said the initial burn-off had been lit despite forecasts for high winds and the landowner would be billed for the firefighting.
"That fire should never have been lit in those conditions and the cost to the landowner will be in the thousands, not the hundreds," he said.
"It's just fortunate a helicopter wasn't needed as well. They are often the most effective way to fight rural fires and they are also very expensive."
Mr Wishnowsky said that should the fire take longer than an hour to fight including travel time, the service had the option to recover costs.
"There is a greater likelihood of cost-recovery invoices being sent to the people responsible or, failing that, to the landowner if a fire is lit inappropriately or lit in inappropriate conditions," Mr Wishnowsky said. A restricted fire season started in Wairarapa on Thursday and permits would be needed for any fires lit in the open air.
"We've had a number of instances recently where fires have been inappropriately lit and it has to stop."
