Tri NZ boss Craig Waugh was delighted with that field and the continued recognition of New Zealand as a major player in the triathlon world.
"I can't think of any other sporting event on the New Zealand calendar that attracts this level of the world's best talent to our shores," he said. "This will be stunning - by opening our doors to the best triathletes on the planet we will showcase Auckland to the world.
"What shouldn't be lost in this also is the large number of international visitors to our shores in the form of the athletes, supporters and fans of the sport, all of whom contribute to the local and national economies."
As well as boasting the leading names in the sport, the World Triathlon Auckland will play host to the Tri NZ national standard distance championships, attracting the best age group triathletes in the country chasing spots on the Edmonton World Championships team.
And with numerous events for beginners and social participants, hundreds of New Zealanders are expected to take part in the weekend and rub shoulders with the best in the world.
"These fields promise to be better even than 2012 when we hosted the World Triathlon Series grand final," said Dave Beeche, chief executive of event delivery partner Lagardere Unlimited. "The thought of Gomez and Mola battling the Brownlees and the leading Kiwis on the Auckland waterfront on a testing and spectator-friendly course is mouth-watering.
"So too the battle between the Brits Stanford and Stimpson against Gwen Jorgensen, Anne Haug and of course our own Andrea Hewitt in the women's."
