"This was a preventable accident, if there had been more appropriate measures and checks in places.
"My sisters and I have lost the two most amazing parents."
There was no way her parents would have boarded the balloon had they known these precautions were not in place, Ms Rouse said.
"The outcome would have been so very different had the pilot been drug tested and held a current medical certificate ... The ramifications of these checks not being in place are endless."
The Transport Accident Investigation Commission has already established that errors by Mr Hopping were ultimately responsible for the crash.
At the time, Mr Hopping had cannabis in his system.
His pilot's medical certificate had also lapsed.
Earlier Civil Aviation Authority (CAA) general manager of general aviation Steve Moore gave evidence. He said he did not believe more frequent drug testing was needed in the adventure aviation industry.
Lawyer Grant Burston, who is assisting Coroner Peter Ryan, questioned Mr Moore on whether there was enough information to warn pilots of the danger of balloon contact with power lines.
Mr Moore said current procedures were sufficient, and believed pilots were aware of the danger of power line strikes.
"There are always risks and I am sure Mr Hopping had no intention of going anywhere near those lines."
The inquest at Wellington District Court continues.
