I think most professional tech worker they are trying to hire would be able to afford a round trip ticket and travel expenses to New Zealand.
But I can't afford it just to hear "sorry, we've decided to go with someone else."
United entered the market within the last two years and that does seem to have driven the prices down a bit.
I fly to Auckland or Christchurch at least once a year with a family of 4 so welcome cheaper prices!
