The family of a woman badly injured in the Mangawhai tornado say it is a miracle she survived when the second storey of her house was blown apart.

Two people were badly injured in the tornado, which struck Mangawhai village about 3am on Sunday morning.

One of the injured was Tina Johnson, who was thrown from her bedroom as the tornado destroyed the second storey of her Old Waipu Rd house.

By “some miracle” she managed to landon the only thing that had a stable roof - a small shed at the back of the car port, said her daughter Jade Johnson-Price.

Johnson suffered a broken arm, cuts, and bumps and bruises all over. She was helicoptered to hospital but it took emergency services some time to get there, due to downed power poles and trees.

Johnson had surgery on Sunday night to help her broken arm and clean-up the lacerations, and medics were happy with how well it went, Johnson-Price said.

“They were really happy with how well her body responded to the trauma ... She was awake and talking most of the day [on Sunday].”

More surgeries will still be needed and she is expected to be in hospital for some time, said Johnson-Price.

But the family are counting their blessings Johnson survived.

“We’re incredibly grateful that she made it out of there alive; the second storey is no longer there.

“We don’t know how it worked but we believe someone was there looking out for her.”

Johnson-Price said the family is also grateful for the Mangawhai community who helped her mother as she lay injured.

With emergency services being hampered, more than a dozen neighbours came to help give support to Johnson as she lay injured on the car port.

“We’re really grateful for all those who came out and helped her, when they heard her crying out for help.”

Johnson-Price said people from the Mangawhai community have also been offering plenty of message of help and support.

She encouraged people to keep themselves safe first and foremost, with a cordon still in place on Old Waipu Rd.

Johnson’s family and close friends are helping taking care of things like insurance, but Johnson-Price said Mangawhai residents have also been picking up mementos from the house.

“I got a message this morning that people have been finding photographs of my mother and grandmother as babies.

“It’s nice that they’re keeping all the stuff safe, and when we can come and collect them, we will.”
