You're not the only person I've heard say that they avoid the TPAC route because they want to avoid the USA. But I've heard people complain that as much as they'd prefer to avoid the USA the flight schedules are far more convenient.
Have you tried the ANZ AKL-YVR connecting to ACA YVR-Europe flights? Canada is far happier about transiting passengers than the USA is. (And if you've tried it and didn't like it, I'm curious why.)
