IIRC the xONEx fares used to only allow one trip between Australia and NZ. This still the case? Also, does this apply to the Circle Pacifics? (I've read the entire star file but want to be sure).

I need to go to NZ for Christmas (exUS), want to go onwards to Oz but may have to go Oz-NZ-Oz and wanted to see if it was an option.
