Christchurch is on the cusp of signing a deal with SailGP to bring the yachting series to Lyttelton Harbour in January 2022.
The event would be a coup for the city with a global broadcast audience estimated at 256 million viewers.
Olympic gold medallists Peter Burling and Blair Tuke will lead the New Zealand entry in catamarans similar to those raced in the previous America's Cup.
The pair remain fully committed to their defense of the America's Cup with Team New Zealand and winning another gold medal at the postponed Tokyo Olympic Games.
18 Olympians with a total of 16 medals will be on the water in the spectator-friendly harbour with the boats capable of speeds in excess of 50 knots.
