"We know you can't be here with us, but we also know you're definitely looking down on the event and smiling."
"When we heard about this kid that did a backflip in New Zealand, we had to look him up and it is a shame he isn't here right now."
Crowds were lining up in droves to check out the high-flying action in its first ever stop in Northland.
Thirty riders, including Kiwis Jed Mildon and Levi Sherwood, put on a show to delight the crowd of 11,000.
Nitro Circus marketing manager Nathan Brown said they were not expecting the crowd level to be so high.
"Definitely was not expecting the turnout from Northland. For our first time up here, it's absolutely brilliant," he said.
"The riders are pumped about the crowd."
Nitro Circus is an "action sport collective" led by Travis Pastrana, featuring his friends and him travelling around the world riding dirtbikes, base jumping, and performing stunts.
