A Givealittle page started by the kickboxing gym Tash belongs to had raised over $4000 on Monday morning.
In a second Givealittle page set up by friends of the family, it says: "We are all broken from the news of this and want to come together for Tash during this unbearable time."
Hurunui District Mayor Marie Black earlier said she was deeply saddened by the crash. She was not aware of the circumstances of the crash or those involved.
"I can only express my deep sympathies to the family at this stage, as they come to terms with a tragedy such as this.
"This is a real tragedy, it's difficult to find the right words to express but my thoughts are with them all."
