If the units are set to South Pacific HQ, and arrive on the first turn, but have no location, they arrive at the South Pacific's main base, which is Noumea. I'd go through the editor and yank out all groups assigned to SoPac, and that should do the trick.
Also, did you delete the airgroups, or erase their base? Erasing their base but leaving everything else produces the result above.
