Six people needed treatment and three were taken to hospital after a boat struck trouble on Otago Harbour amid windy conditions this morning.
Police were notified at 10.10am that "a dragon boat or waka" appeared to be in trouble approximately 150 metres from shore.
A police spokeswoman said all six people involved in the incident were safely back on shore.
"Three of them [were] transported to the hospital to be treated for possible hypothermia."
