Organisers hope the haka, to take place on Nelson's Tahunanui Beach on September 11, will break the existing Guinness World Record of 3264 performers, set in 2008 at Ngaruawahia.
Communities across the top of the South Island are invited to take part in the record attempt to celebrate the lead-up to the World Cup.
"The haka is our way of gathering our energy to welcome the world, readying ourselves for all that we are going to offer the world," lead organiser Mike Elkington said.
The haka to be performed is Ka Mate, which is performed by the All Blacks.
Organisers said while it was not viewed favourably by some iwi, in a modern context it was used to celebrate being a New Zealander.
There will be a minute of silence before the haka to acknowledge the significance of the date to Americans.
