Quinn said he hoped the Wellington public would come out in numbers to the event this weekend and also fired a shot at criticism of the event.
Quinn has been on the sevens circuit since it started and was at the Rio Olympics to commentate on the sevens. Although he is not commentating at the sevens this weekend in Wellington he will be at the event.
"The sport is as good as ever. You look round the world and it is still very popular. Dubai, they get 40,000-plus. Hong Kong is still a very popular traditional event. In Las Vegas, they got 70,000 in total, a record crowd ... New Zealanders have become used to the event," he said.
"They can sort of take it or leave it. I just hope it is a nice day and people come out to see this great event.
"They don’t have to go for the whole day. It is a long time. But they can go and see some of it."
Quinn said very few events in New Zealand sold out these days.
"How many grounds are packed out these days? Do Super rugby games get sell-outs? The Phoenix? I’ve seen empty seats at your ground [Forsyth Barr Stadium] down there.
"There is a little bit of a thinking that in New Zealand you can go down to the shop and for $300 to $400 you can get a 46-inch HD TV and you can just stay at home and watch it. Rather than spending money and go to the ground like to used to in the good old days."
Quinn said the drinking at the event had to stop.
"But it is unfair to be critical of the sevens organisers. You can’t behave like that in any other drinking establishment so why should the sevens be any different. You behave like that at a pub and you’ll get thrown out. The sevens was no different."
He said it was only a very small minority and 99.9% of the crowd was well behaved.
The Wellington sevens had been up and down over the years, he said, and survived.
He was critical of the comments of sports administrator Martin Snedden, who said in the media earlier this week that the event had reached the end of its life cycle.
"I was very disappointed in that. Coming from someone who was involved in some low-rent boxing promotion. Setting up some boxing events where someone is going to get killed one day."
He had a lot of time for Snedden and enjoyed his company but felt his comments were not called for and were a "kick to the shins" of the event.
