"I looked and could see what I thought was a dolphin, then a whale but realised it was people and a boat," she said.
She alerted her husband, Brian, who is a senior firefighter with the Onerahi brigade, who went up the hill with binoculars to get a better look.
"I could see a person waving both hands above their head looking distressed," he said.
Another few minutes and the boat would have drifted behind rocks and would not have been visible from shore.
Together Mr Clancey and lifeguard Mark Bourneville, a former Kiwi rugby league international, dashed out through the choppy water on the outgoing tide in a ridged inflatable boat.
"They were white and you could see in their eyes they were slipping away," Mr Clancey said. "I've never seen people that are alive, looking so dead."
Mr Bourneville said all four men were in a really bad way and had been bashed around in the hour or so they had been in the water.
"They were battered and weren't coherent. One was foaming at the mouth indicating they had taken on salt water - that's a bad sign," Mr Bourneville said.
