A mother has described her traumatic experience being trapped on a roof of her creaking home with children desperate to be rescued from rising floodwaters.

Huia Ngātai climbed onto the roof of her Te Araroa home as flood waters overwhelmed their property.

She said at about 2am the water was at a level near the bridge at the edge of the property that “didn’t feel right” despite never having flooding issues before.

“We went home and woke our kids,” Ngātai said, “planning to put them into the truck as a precaution.

“Within about five minutes of doing that, we saw our vehicles start floating down the driveway.

“Everything happened so fast. We realised straightaway it was too late.”

A wall of water then rushed toward the family, which the mother described as a “tsunami” and forced them to climb onto the roof.

“It was absolutely terrifying. My children were screaming and crying, and we were all in shock.”

As they moved toward the highest point, the deck roof suddenly collapsed.

“By that point, the water had risen within seconds to the bottom of the roof, rushing down both sides of the house.

“We could feel the house moving and creaking underneath us.”

Ngātai described the noise as “unreal”, with boulders crashing like thunder, trees breaking and nonstop heavy rain.

The family huddled together for warmth while emergency services called her, advising them to stay on the roof and keep calm.

“I was completely distressed and kept begging for a helicopter.

“There were emergency crews nearby, but they couldn’t reach us because it was too dangerous.

“I kept telling them we were basically sitting in a river and ground rescue wasn’t possible.”

The thought of helicopters being unable to reach the family made Ngātai believe they were about to die, but her sister stayed on the phone, providing updates and pushing for help.

She credited a pūriri tree behind the house with helping to save them, as it helped to divert floodwater around it.

As daylight came, the floodwaters started to drop and revealed extensive damage including vehicles flipped upside down.

The family then climbed down from the roof and were greeted by emergency services at the end of the road, later being airlifted to the Te Araroa clinic.
