Jet boating is a big deal in New Zealand. It was invented here, after all.
You can jet boating all over the country, both the North and South Island.
Huka Falls are north of Lake Taupo and the most visited waterfalls in New Zealand. You can take a jet boat ride right up to the rapids.
The Shotover jet is the most famous jet boat ride in the world. From Queenstown you head down to the Shotover river. This narrow river in a canyon is an adrenaline filled jet boat ride.
