Her death lifted New Zealand's Easter road toll to four.
Central Hawke's Bay District Mayor Alex Walker said her thoughts went out to everyone involved in the crash.
She said the thoughts of the Hawke's Bay community are with the Hunter family.
Former Central Hawke's Bay Mayor Peter Butler said he did not know Jane Hunter, but knew her husband, James, well.
He said they were a well-respected family in the district and it was a devastating loss for the Porangahau and Blackhead community, as well as the wider Central Hawke's Bay.
