A New Zealand zoo has decided that it will not euthanise an endangered Sumatran tiger that attacked and killed an experienced zookeeper.
The male tiger named Oz killed 43-year-old Samantha Kudeweh on Sunday morning inside the animal's enclosure at Hamilton Zoo.
Sumatran tigers are considered critically endangered, with less than 400 of the tiger subspecies still living in the wild on the Indonesian island of Sumatra, and Oz was said to be "vital" to the zoo's breeding process aiming to conserve the animals.
The zoo, which houses five Sumatran tigers, is owned and operated by Hamilton City Council.
Lance Vervoort, the council's general manager, said there was always a risk for zoo staff in managing big animals like Oz but the tiger did not pose a wider risk.
"Oz is a significant animal for his species," Mr Vervoort said. "He is the father of our two cubs, and he is vital to the ongoing breeding programme to conserve this rare species."
Mr Vervoot said the view of zoo professionals was that the attack was in line with the tiger's natural instincts.
Ms Kudeweh had been a zookeeper for more than 20 years and was married to another zoo professional. She was the mother of two children, aged nine and three.
She was the zoo's curator, responsible for organising what animals the zoo obtained and how it looked after themm and had worked at several zoos before starting at the Hamilton Zoo in 2005.
She wrote about her job on the zoo's website: "For me the best thing about my role is the opportunities to interact with other species one to one, but there is a downside and that is having to say goodbye to animals. That part never gets any easier."
The zoo was closed after the attack, and will reopen on Thursday.
Mr Vervoot said the zoo would not comment on what went wrong until an investigation is completed.
