With Covid-19 preventing non-Kiwis from entering, Quinn will watch the milestone achievement for the park from Australia.
"It is going to be horrible," Quinn said. "Hosting the Grand Prix is something I have blatantly and publicly said I would move heaven and earth to make happen.
"I couldn't have guessed that when we actually made it happen and I wouldn't get to be there. But these are crazy times – and so far we have got through them.
"All I want to do - at 63 years old - is go between Australia and New Zealand.
"It is one thing having the track and getting to host the Grand Prix but to be able to race in a Grand Prix - I would have paid whatever to race in that Grand Prix and celebrate my mate's Kenny's 50th start, that would have been just amazing."
When it was announced that Hampton Downs would host the iconic event the decision, made in conjunction with series promoter Speed Works Events, Toyota New Zealand and MotorSport New Zealand, came as a relief in many ways for Quinn.
"There has been no hiding the fact that it has been one of the objectives that I have wanted to do since getting involved with New Zealand," he said.
"My involvement goes way back to the first couple of Targa rallies that I did – it was good fun and a good bunch of guys and they punch way above their weight.
"I had the chance to build Highlands and that has been a great experience and a great journey and then I had the opportunity to do the Hampton Downs thing and that was another one.
"Through that total journey there was nothing more evident to me than New Zealand has a marvellous place in the world of motorsport globally. It is world renowned and I built the museum at Highlands to recognise that.
"It would be the understatement of 2021 to say that I am super excited that it is going to be held at Hampton Downs.
"There have been a lot of chess moves and things that have had to happen, stars needed to align and people needed to have the confidence that Josie and the team could deliver.
"I have been super impressed with both parks in New Zealand - the teams there have done a marvellous job during Covid and I have been impressed with how they handled everything.
While the future beyond 2021 is yet to be determined, Quinn is confident the team will deliver an event he'll be proud of from his armchair in Byron Bay.
