So you're on your way to Central Otago and you're hoping to have a bit of couple's time at the Onsen, you've bought your tickets for the Earnslaw and to take the kids and show them the big steam engine on Wakatipu, and you take your test and it says you're positive. Are you seriously going to isolate for seven days in one place and miss your flight back to Oz, have to buy extra accommodation, and not be able to use any of the other tickets? You're just not going to do it.
