"We feel optimistic that with proper hospital care we will eventually get her back, but the reality is that this will happen in New Zealand far more easily than in the US. She needs to be at home surrounded by her family," said Courtenay.
"People have generously donated just over $20,000 but it could cost around US$270,000 ($NZ415,000) just to Medevac her home, and then there is the cost of ongoing care, so you can see how far we have to go," said her step-sister.
"Our parents are retirement age and we are all helping as much as we can but we thought we need to get some more financial support for what is certain to be almost unaffordable."
Family and friends have set up two fundraising pages:
• GoFundMe page
• GiveALittle page
