One person died after a crash on the Hollyford River on the Fiordland National park last March, and another person died in a jet boat crash near Wanaka Airport last February.
Nine people were also injured in a jet boat crash on Queenstown's Shotover River in Skippers Canyon on February 23 last year.
Ten people were on board the boat when it crashed into rocks.
The passengers were part of a group of tourists from Thailand and Canada.
