The fundraising page had been set up to provide financial support as well as messages of condolence.
"If you would like to donate, every little bit will be a great help to the family. If you are not able to donate don't forget you can still leave messages and comments for Arohaina and the kids to read."
So far more than $1700 has been donated.
Police are investigating the cause of the crash and could not comment on Harrison's history.
