Clarke Johnstone, winner of the Adelaide four star event late last year and who would most likely have been picked for the WEG team but for injury to his star horse Balmoral Sensation, is ranked No 19.
Britain, with three of the four top-ranked riders, is the only country who can match New Zealand's standing in the discipline.
The Prices have had a stellar year.
Tim Price's win at Burghley followed back-to-back four star wins for his wife at Badminton and Luhmuhlen in Germany, giving them the most recent three trophies on their mantelpiece.
Four of the six classic crowns are currently in possession of New Zealand riders.
The win was also Price's second in the elite class, matching his wife's pair.
Only Britain, with six, have more riders in the top 20 than New Zealand's five. The pair will arrive in North Carolina among the top picks to be vying for the title.
Todd is also in the New Zealand team, along with fellow veteran Blyth Tait and Dan Jocelyn.
The top 20 rankings is rounded out by four Americans, two Australians and one rider from each of France, Germany and Ireland.
