NZALPA Senior Technical Officer Dave Reynolds said it's essential that government and stakeholders work together to integrate RPAS or drones safely into New Zealand airspace.
"Operators of these devices, no matter how small, need to fully understand the rules and their responsibilities," he said.
"Education is vital, as is operator responsibility, and this is why we are advocating for mandatory registration of all RPAS above 0.22kg (0.5lb) in weight, as is currently required in the USA.
"It is also NZALPA's view that large RPAS above 25kg (55lb) should be operated in accordance with the same or equivalent requirements applicable to other aircraft sharing the same airspace, including operator competency and medical standards."
A helicopter had been flying in the area at the time and, soon after Mr Reeve stopped flying, started fighting the fire with a monsoon bucket.
Reeve said he would have given way to the chopper if he had seen it and, if necessary, brought his drone down in a tree, the court heard.
He claimed that he had been flying below the treetops.
But a policeman at the scene, who gave evidence which was accepted, estimated the drone was about 1.5 times the height of the trees in altitude.
And a video taken by the drone showed that it was "significantly above" the treetops.
Helicopter pilot David Askin didn't know about the drone until he saw drone footage on the news that night, which angered him.
Judge Gary MacAskill found that Reeve did cause danger to Mr Askin and his helicopter, getting as close as 120m.
"It was possible that the RPAS and the helicopter would collide. That possibility was not so speculative or unreal as not to amount to a danger," he said.
The trial heard that TVNZ reporter Joy Reid spoke to Reeve while out reporting on the fire and had asked to use his footage, which he agreed to for a fee of $200.
She says at no point did they speak about Reeve having authorisation to fly the drone in the area.
The judge said Reeve had no reason for creating the danger beyond videoing the fire and the helicopter for his own interest, and perhaps, possible sale to news media.
Reeve was also found guilty of illegally flying his drone in controlled air space at a January 20, 2015 fire, again at Pines Beach.
Reeve was remanded at large for sentencing on a date yet to be confirmed.
