Top 4 teams that were still to qualify at the NZ Worlds were to take up the remaining 4 slots.

The top 4 teams in order were....
Canada, Austria, New Zealand and the Ukraine

The next 4 teams that were seeking to qualify in order of how they finished at the Worlds......

Russia, Puerto Rico, Brazil, Poland and Venezuela

I believe Booth was seeking a wildcard entry for Puerto Rico, one of the teams (along with the US) that were involved in their code zero training camps. They were denied.
