The competition is set to take place at the new 50,000-seat Kai Tak Stadium for the first time from March 28 to 30, although the daily capacity for the event will be set at around 47,000.
Organisers claim that they have sold 38,500 three-day passes, while Hong Kong China Rugby (HKCR) states that all of its corporate hospitality suites are sold out.
Furthermore, the governing body says that 99 per cent of the 138 temporary corporate boxes have also been sold.
“Hong Kong China Rugby is delighted to celebrate another milestone in the prestigious history of the Hong Kong Sevens,” said HKCR’s executive director of commercial and business operations, Bryan Rennie.
“Revenues from the tournament are put right back into the sport and the Hong Kong community, and we are grateful for the support of our fans from around the world.
“It is a great honour for the Sevens to be the first international sporting event to be held in the new Kai Tak Stadium, and we are excited to be bringing a show and a crowd worthy of this once-in-a-lifetime moment.”
Organisers of the rugby event are predicting that sales will rise even further in the two weeks leading up to the opening day as they aim to sell out.
Since 1982, previous editions of the tournament have been held at the 40,116-seat Hong Kong Stadium in Causeway Bay.
For the foreseeable future it will be held at Kai Tak Stadium, which is part of the Kai Tak Sports Park that opened at the beginning of this month.
Alongside the 50,000-capacity stadium, the complex also includes the 10,000-seat Kai Tak Arena and the 5,000-capacity Youth Sports Ground.
Tickets for the Hong Kong Sevens are available via the event’s official website.
An adult three-day ticket is priced at HK$1,950 (£193/$250/€230) while children’s tickets for fans aged 12 and under are available on a first come, first served basis at HK$950.
