Just minutes from Auckland International Airport and built over a large wetland, Butterfly Creek delivers more than 800 free-flying tropical butterflies. Complete with waterfalls, ponds, lush foliage, turtles, fish, and exotic birds, it allows you to get up close to stunningly colorful butterflies. If you're lucky, you'll see the world's largest moth, which has a wingspan of up to 280 millimeters (11 in.); be on the lookout for tarantula, lizards, and giant weta. Most of the attractions are indoors, so it's not a bad choice for a rainy day.
