The AJ Hackett bungy jump outside Queenstown is outrageous in terms of pricing.

Most jet boat rides aren't much better.

That AJ Hackett site does 2 x 5-6 jumps per hour, according to my rough count, at an average of $NZ160 each. Nice little earner, with few big costs - then there are the DVDs, T-shirts, and coffees. People queue to do it though.
