"So it is unfortunate on her behalf but I'm more than happy to step forward," . she said.
She is the third woman with strong Rotorua or Te Arawa connections to win the national title.
Rotorua district councillor Maureen Waaka (nee Kingi) won the title in 1962 and Linda Edward (nee Ritchie) was crowned Miss New Zealand in 1971.
Mrs Waaka told The Daily Post Ms Bennett had inherited her sophistication and beauty through her family.
"I saw her on television and she is a lovely looking girl who is very well spoken. The Bennetts have a long history here and on the coast."
