He noticed movement inside as he got nearer and discovered the woman trapped in the car.
Water was up to the front windows and had filled the car.
“If the trees hadn’t stopped the car... [it] would’ve just gone down the river,” Holland said.
“They would’ve never got out because the water was flowing that fast.”
Holland opened the boot of the car and helped her into the back where it was shallow enough to get out, grabbing her belongings.
Former Mangamahu resident Carl Roberts arrived at the scene and quickly waded in to help Holland. He carried the woman out of the water with Holland following behind.
“You couldn’t see where your feet were going half the time,” Holland said.
“When you looked behind you ... there were logs going past.”
The cold water was up to the woman’s waist at the car and rose visibly while they helped her, Roberts said.
After getting back to their cars, Holland drove the woman to her family member’s home nearby.
Roberts’ mother, a nurse, Sandra Roberts, checked in on the woman later that day.
Holland helped her family tow her car out of the mud on Monday.
