Jumbo is the same elephant that killed a vet at Franklin Zoo in Tuakau in 2012.
Dr Helen Schofield died in April 2012 when Jumbo picked her up and crushed her with her trunk.
A coroner found Jumbo may have been frightened by a shock from an electric fence, and found Schofield ignored her own safety guidelines by entering the enclosure.
Ratcliffe said he'd been inundated on Facebook with comments from people who were saddened at the news of Jumbo's death.

"She's remembered by thousands throughout the Pacific," Ratcliffe said. "She was an icon and such a beautiful elephant."
He said he loved all the elephants he'd handled over the years.
"I've handled over 40 odd elephants in my life on this planet and you couldn't help but love them."
Jumbo was born in the wild in 1973, but at nine months she was taken into captivity at London Zoo. She ended up at Honolulu Zoo for a brief period before the Whirling Brothers Circus brought her to New Zealand in 1978.
After Schofield's death, Jumbo was later sent to San Diego Zoo.

Ratcliffe said the zoo had always kept in touch with him about how Jumbo was doing, but due to an aneurysm in his brain he was unable to fly over and see her.
"I just feel gutted, you know, I feel so sad about it, you know, because we had so much life together, it's just like losing a wife.
"She was part of our family ... how do you say goodbye to a friend?"
Ratcliffe said he didn't go to his own mother's funeral because he had to care for Jumbo, but his mother would have understood.
