Two men were swept 1km down the Kawarau River and stranded on a bank after jumping in after a dog yesterday.
Emergency services were called to the scene at Rafters Rd, off the Gibbston Highway, about 4pm.
Queenstown harbourmaster Marty Black said the men were with a group of about five people having a picnic on the river bank.
While they were throwing sticks to the dog the animal fell into the river and the two men jumped in after it.
"They were swept away about a 1km downstream."
