Smith and Thompson were separately flown to Wellington Hospital on Tuesday in serious conditions after the crash on State Highway 1 near the Ōhau River Bridge.

"The family are pretty devastated at the moment. It's been hard," Ili said.
"Kendra was wailing last night when she found out she lost the baby. She's a lot better today than she was yesterday.
As a young single mother, Smith took up the reins of the president of the Featherston Rugby Club before she met and fell in love with Thompson.
Smith has a young son from a previous relationship and Thompson has three girls, also from a previous relationship.
Family friend Ritchie Wards says the pair are "committed and amazing parents".
Ili says the club was struggling before Smith arrived and poured her heart out into it, bringing it back from the brink.
The family have been overwhelmed by the support of the community, Ili says.
"The community are really good people, we come together and work hard to put things together. [They] have been very good," she said.
Smith's mother, Ili's sister, is driving to Wellington from Paraparaumu each day to be with her daughter and Thompson.
Some of the money from the Givealittle will go towards travel expenses, as well as medical costs, family-related costs, and potential modifications to living arrangements.
