A jetski accident at Matakana Island's popular Hunters Creek yesterday resulted in the rider and passenger being treated at Tauranga Hospital after their craft hit the old ammunition barge at about 3.30pm.
Tauranga Coastguard operations manager Simon Barker said something happened to the jetski and the rider was unable to avoid the barge.
First on the scene was the regional council's boat, Pumanawa, followed by Tauranga Coastguard's vessels, Sealegs Rescue and TECT Rescue.
The coastguard crew administered first aid, with the injured loaded aboard each vessel which took them across the harbour to waiting ambulances.
On Friday, a couple and two children using a jet ski in Tauranga's harbour were rescued by local police and the Tauranga Coastguard.
