Olympic medallists Alistair and Jonathan Brownlee and Javier Gomez will line up in Auckland for the ITU world triathlon grand final on October 21.
The event's chief executive officer Dave Beeche said the inclusion of the world's top trio was a major boost.
"Ever since London everyone has been asking if the Brownlees and Javier will be lining up in Auckland, and while nothing is certain with injuries always a threat, to have all three stating that they will be in Auckland at this stage is fantastic.
"They, and the remainder of the best in the world, will put on a great show - along with our own best in the likes of Bevan Docherty, Kris Gemmell and Ryan Sissons."
Alistair, the Olympic champion, has had his ITU season curtailed by injury and it is unlikely he will have raced often enough to contend for the overall world title.
Younger brother and bronze medallist Jonathan is currently in second in the standings with three races left.
"It's a good course in Auckland," Alistair said, after the Olympic race. "It's hilly which makes it easier for a break to stay away on the bike. I want to go and support Jonny to try to win the world title."
The final field won't be confirmed until closer to race day.
Beeche hopes to confirm a number of the top female triathletes, including medallists from London, within the next couple of weeks.
