Ski Racing New Zealand chief executive Simon Mills said the three-day event, from August 28 to 31, would also provide a blueprint for the FIS skiing events at next year's inaugural Winter Games New Zealand, planned for the region.
The National Championships will also include a Super G for the first time at Coronet Peak and a giant slalom.
The Super G is a test event for the Winter Games and a technically challenging course has been homologated during the summer.
Mr Mills said the organising committee had worked solidly for several months to ensure the premiere event on the New Zealand ski racing calendar was a success.
"The concept of holding a night slalom is fantastic for both the competitors and spectators.
"Extra lighting is being installed and it will be integrated with existing lighting to ensure the course is adequately lit. It will be a unique event."
The races begin on August 28 with the Super G, followed by the giant slalom on August 29 and the slalom on August 30.
The first run of the slalom starts in the afternoon and the second run will begin for the women at 6.15pm and the men at 7.15pm.
August 31 has been set aside as a contingency day.
Mr Mills said the country's top skiers would compete in a high calibre field of internationals, with World Cup athletes from Sweden, the United States, Italy, Japan and Norway likely to be in the starting line-up, providing competitive racing.
"We are expecting several slalom skiers ranked in the top 30 in the world to compete in the men's field which is huge for the New Zealand event.
"In the women's field there will also be some highly ranked skiers training in the area who are expected to enter and help lower the penalty."
New Zealand will be without its top men's skier, Ben Griffin (21), of Ohakune, who is recovering from injury, but Volkswagen National Ski Team members Mark Bridgwater (22), of Christchurch, Tim Cafe (21), of Queenstown, and Angus Howden (27), of Wellington, will be flying the flag for the Kiwis.
Up and coming younger athletes will also be doing their best to impress, including Wanaka's Leighton Winsloe, who reached the eligibility criteria for the national team.
In the women's field the focus will be on Volkswagen National Ski Team members Janelle Miller (22), of Queenstown, and Sarah Jarvis (22), of Hamilton, with emerging young skiers Harriet Miller-Brown (16), of Queenstown, and Alexandra McGlinn (16), of Christchurch, also hoping to perform well.
Mr Mills said the Volkswagen National Development Team members would also be on show and some good results were expected from the group of under-19 skiers.
"Some of these younger athletes are showing a lot of promise and the National Championships will be a testing opportunity for them."
