Kaminski said the balloon would take off into the Rotorua sky every 10-20 minutes with 20 people standing harnessed in the circular gondola.
"It gives a pretty exciting ride and spectacular views," Kaminski said.
Those wanting an extra thrill can try the Orbster - where riders are harnessed and hang outside the gondola from the Orbserver's suspension ropes.
Kaminski compares the Orbserver to a giant helium filled party balloon but made to tough safety standards - and much more expensive to fill.
It takes $100,000 worth of helium to fill the giant balloon and then it is topped up as needed.
Kaminski said the Orbserver was safe for all ages and fitness levels and helium was ideal because it was lighter than air and was neither flammable nor explosive.
"Internal lighting will make the bright yellow balloon and its red gondola a highly visible and spectacular sight for many miles, especially at night time," he said.
