"We have known from day one that Auckland would host the World Masters in 2017 and, while further analysis needs to be done, we are confident it won't impact negatively on our games.
"The World Masters is a first for New Zealand and, in fact, the New Zealand franchise has been instrumental in helping Auckland prepare - we have been liaising regularly. The World Games, of course, will attract large numbers of international visitors and it could be some take part in both games."
The Worlds is the largest multisport event in the world - in terms of competing athletes, it is bigger than the Olympics.
The Auckland event is expected to attract 25,000 athletes who will compete in approximately 30 sports across some 45 venues, with more than 100 countries represented.
In contrast, the New Zealand Masters in Wanganui has at peak attracted over 8000 competing in 67 sports.
The Auckland launch this week also included the announcement of a group of ambassadors dubbed the "famous five" who have agreed to contribute their time to promote the games.
The five inaugural ambassadors are Olympic swimming bronze medallist Anthony Mosse, Olympic triathlon gold medallist Hamish Carter, real estate businessman and masters sports disciple Garth Barfoot, former Silver Fern and TV sports presenter Jenny-May Coffin and one of New Zealand's leading sports administrators, Susie Simcock.
