Spotting an upside-down raft and then searching for its occupants made for a much more eventful afternoon than a group of teenage paddlers near Queenstown had expected.
In the end, everyone on the Kawarau River emerged safe and well on Saturday, but some were given a significant fright.
A police spokeswoman said the incident happened about 3.30pm.
"All and sundry responded.
"Ambulance, police, Fire and Emergency New Zealand, Search and Rescue, the Otago and Queenstown rescue helicopters — quite a few different folk headed to the scene."
