This is one of my favorite waterfalls in New Zealand!
The Kitekite falls track in Auckland is a short 1-2hr loop walk. You can swim at the base of the waterfall or continue up the trail to the top of the falls and swim in the gorgeous infinity pool up there.
The trail is well maintained and easy to follow. Be prepared for lots of stairs on the track to the top of the falls.
Extra info:
Distance: approx 2.7km
