The company Queenstown Rafting has agreed to foot what is likely to be a bill for tens of thousands of dollars to clear a slip above the Shotover River.
Efforts to dislodge the 100,000 cubic metre slip, which has been hanging precariously for five weeks, could begin as early as Wednesday.
Queenstown Rafting manager Vance Boyd says the slip is not only putting people's lives at risk, but is affecting his company's livelihood.
"At this stage we're accepting the cost for our commercial gain because the alternative is simply too unpalatable for us", he says.
Vance Boyd says water will be directed at the base of the slip in an attempt to sluice it away.
He does not know how much the operation will cost.
