Organiser Simon Green said the evening would feature 10 bouts, four of those between women.
Some had been training all year, through public boot camps, while others had been through the pre-qualifier, qualifier and Thriller camps, which have been running for almost six months.
''In terms of just a general bunch, I'd say they'd be some of the best technical fighters we've ever had on the cards, which is great.''
The final fight on Saturday night will feature chef Paul Kenward (34) and plumber Shane Dunne (31).
''We've made that the last fight because, technically, they would be the best match-up that we've got on the card.
Thriller will also raise money for The Branches Charitable Trust, which runs one of New Zealand's oldest full immersion outdoor education camps for Wakatipu High School pupils.
Mr Green said items going under the hammer in a live auction this year included a basketball signed by New Zealand-born professional basketball player Steven Adams and former SAS corporal and Victoria Cross recipient Willie Apiata, as well as a boxing glove autographed by Joseph Parker.
Doors open at the Queenstown Events Centre at 6pm on Saturday ahead of the first bout at 7.30pm.
