Both vehicles looked "wrecked" when they were eventually pulled out of the water, she said.
"The one yesterday was a diesel and the water was in the engine." She didn't mind going out to help, but was worried people were ruining their cars, and putting themselves at risk.
"When the tide's coming in it comes in quite dangerously at times.
"They just don't think to check it out first."
The swollen creek was also giving nearby residents grief, she said. Too much water was flowing down it, much of it from a dam upstream.
During heavy rain, the creek was put under extra pressure when water from the dam was released.
Meanwhile coastal erosion was eating away at the creek from the mouth end, changing its pathway, she said.
"The Orowaiti [River] and Deadmans Creek are both coming out in the same area at the moment."
Some residents had been forced to move and replace fences. One had to replace theirs in as little as six months after replacing it the first time, she said.
