Late last year, a young Australian Muay Thai fighter lost her life while weight cutting before an amateur bout. Trying to rapidly drop to the 64kg limit for her class, Jessica Lindsay passed out while on a run and died in hospital four days later.
It was the second weight cutting-related death in Australia in 2017, and prompted King in the Ring promoter Jason Suttie to take action against the practice to ensure nothing similar would happen in New Zealand.
"Our show is the leading kickboxing show in the country, and it's a platform for our Kiwi fighters to fight overseas, so we just though why don't we lead the way and start a safe weight cutting regime," Suttie told the Herald.
"I just thought, man, this is the show to hopefully lead the way for other promoters anywhere in New Zealand to Australia to start doing it."
The event, which features a professional eight-man elimination tournament as well as a mix of other professional and amateur bouts, has been a launching pad for a number of Kiwi mixed martial artists, with past winners including UFC stars Israel Adesanya and Dan Hooker. Friday's show will be the first eliminator with mandatory weight cutting restrictions.
