Australia, New Zealand & the South Pacific - Apia - Tongatapu

I'm trying to find an airline which runs non-stop flights on Thursdays or Fridays. Air New Zealand runs a non-stop on Wednesday but that is not working for me. The only flights I could find on other days connect through Auckland or Nadi. Thanks

There aren't any AFAIK. This is the south pacific where flights are few.

NAN and AKL are the only hubs in the region.
