If you have ANY FREE TIME I still think you may be able to fit this in. They will pick you up and take you and the boats go out about every 15 - 30 minutes or so. The hotel can call for you once you get there if you decide to try and do this. It takes no longer than 15 minutes from town to the river. The ride only lasts about 10 - 15 minutes. The actual jet boat is where the experience lies not necessarily doing it on the Shotover River in Queenstown, that is just where it started I believe and therefore the most well known. So any N.Z. jet boat will be basically the same experience. It is about the speed in just inches of water, proximity to the banks, and the quick turns. In particular the Hamilton Turn which is a 360 degree turn is what is so much fun.

I am sure before it is over anyone who wants to do a jet boat will get a chance. If there is one in Christchurch that would be a good place to do it. The town is quaint and very English and perhaps I have been there one too many times but if you want to do the jet boat take that excursion instead you will not be missing anything major in Christchurch.
