Well, when we were in NZ last time, we:
Bungi jumped,
watched other people bungi jump,
rode a dry Luge on a huge hill overlooking Queenstown,
Cruised on the huge lake Wakatipu in a ship "built in the same year as the Titanic, only ours hasn't sunk yet,"
Watched people parasail,
Flew around in air so clear you can't even see it to believe it,
Ate wonderful food everywhere we went,
Drove on the wrong side.
Learned about the Maori,
Watched the Maori do all kinds of native dances and the like,
Hiked right through a couple of the places they filmed the Lord of the Ring movies.
Jet boated up (and back down) the Dart river.
Woke up to the mist on the glass-smooth lake - and watched people water ski in water that was 40 degrees.
(ever see somebody walk up the rope and climb into the boat as an involuntary response?)
Learned that the letter 'e' should only be pronounced as "Eee" (how would you like your Eeeegs 'tis mornin' mate?)
Met wonderful people who were actually glad we were there.
Cut the prices in half at the stores: and paid no sales tax (actually VAT) by showing our passports.
Almost purchased a nice little 2 bedroom house with a view for $35K.
Sailed in a regatta on the harbor in Aukland (came in first only to be disqualified - we jumped the gun),
Ate lunch at the Yatch Club where the America's cup was on display. The actual one.
And then on the second day.....
Go to the many NZ websites and check it out. What a wonderful place to visit.
