The father of a 21-year-old au pair living with a Whanganui family rushed over from their home in Canada when he heard his daughter had been in a car crash.
Angelika Melisa Loukas died following the crash on Waitotara Valley Rd in the early hours of Sunday.
Loukas, who lived in Waitotara Valley with her host family, was in the vehicle when it lost control and careered about 100m down a steep hill.
Waverley fire chief Alan Hickford confirmed to the Herald on the weekend that another occupant in the car walked around 3km to find help for Loukas.
He had walked past two houses he didn't see in the pitch black, before he finally managed to call for help about 4.20am.
Hickford said the man had no idea where the crash occurred and it was simply a case of firefighters using their nous and spotting any suspicious clues along the side of Waitotara Valley Rd that led them to finding his injured female friend.
He described the hill as being "very, very steep" and after finding the injured woman firefighters carried her about a further 100m to the waiting rescue chopper.
Loukas suffered critical injuries and was flown to Wellington Hospital about 90 minutes after the crash, reports Fairfax. She died from her injuries two days later.
Police said a male occupant from the vehicle was also injured in the crash, which they are investigating.
Speaking to Fairfax from Canada, her mother Anne Loukas said Angelika's father Gus Loukas rushed to New Zealand upon hearing the news.
He later video-called a group of devastated friends and family, including Angelika's 19-year-old sister Athena and her 22-year-old brother Theodore.
Anne said the family had initially been told Angelika was in a stable condition, but she didn't make it.
"But by the time I got home, the neurosurgeon talking to my husband said she didn't make it," she said.
Her daughter was affectionately known as "Baba" (Greek for "baby") by her family and had come to New Zealand in May.
"She always wanted to travel and she was always talking about New Zealand."
Back in Canada she had been studying psychology at the University of Ottawa, but had decided to take a break to live with a Whanganui family and work as an au pair.
"She loved the boys and the mum was like her best friend," Anne told Fairfax.
Anne said Angelika had bonded with the young boys and her host parents Daniel Mccoll and Alice White.
Angelika was a friendly, outgoing girl who had loved New Zealand.
"As a middle child, she would give everything she had to make other people happy."
Angelika's body has been cremated and taken back to Ottawa in Ontario.
