Max Tibby, 16, from Adelaide said he'd tried jet boating in Taupo and the Agrojet was a similar experience but better, a bit faster with more twists and turns and the driver more skilled.
"You don't expect it to be as good as it is - you feel like you are flying."
He'd also done the Freefall Xtreme.
"It's crazy - really fun. I don't think I could have done this sort of thing without Scouts," he added.
Agroventures sales and marketing manager Debbie Guptill said the park had been closed to the public to give the Scout group exclusive use but it was "all hands on deck".
She said staff were used to working at full capacity and the numbers yesterday were similar to locals' weekend when 1500 people came through the park over two days.
