The cost of bringing Auckland Zoo's new elephant, Anjalee, to New Zealand in June included $600,000 to build a quarantine facility in Niue.
Documents released by the council under the Official Information Act, show of the $3.2 million cost to acquire two new elephants, $600,811 was used to pay for the facility.
The 1.7-tonne female Asian elephant was brought from Sri Lanka to New Zealand, via Niue for a three-month quarantine, to keep the zoo's 32-year-old female elephant Burma company.
Burma has been lonely since her friend Kashin died in 2009 and the idea is for her to take on the role of matriarch to 8-year-old Anjalee.
