WELLINGTON, May 27 (Reuters) - A rare white tiger mauled and killed a New Zealand zoo keeper on Wednesday, local media said. The attack occurred when two keepers went inside to clean the tiger's cage at the Zion Wildlife Gardens in the city of Whangarei, about 200 km (124 miles) north of Auckland. The NZ Press Association reported the tiger had grabbed one of the keepers and would not let go despite the efforts of other staff. The attack was said to have been witnessed by a group of tourists. The wildlife park was closed and the tiger killed. Police, agriculture and health and safety officials were investigating the attack. A white tiger at the same park was reported to have been involved in an attack on another keeper earlier this year. The keeper had to have surgery to the knee. The zoo houses 42 rare lions and tigers and was used as the setting for a reality television programme about its celebrity founder Craig Busch, known as the "Lion Man". (Editing by Miral Fahmy)
