From 2002 the zoo began renovating its aging cages, shifting toward open spaces and habitat-style enclosures in place of narrow cages. Then, on 29 May 2017, it closed completely so that it could be rebuilt together with Hsinchu Park. It reopened on 28 December 2019, and the opening ceremony was attended by President Tsai Ing-wen, who toured the grounds with the mayor of the time, Lin Chih-chien. The new zoo runs on three core ideas: animal welfare, education, and recreation. In practice that means opening up the cages, giving animals more room, restoring something of their natural habitats, balanced diets and a proper medical system. It flips the old idea of animals being looked at inside a cage. Visitors responded in force. More than 20,000 people came on the first day, and about 370,000 came in the first month, a record. The collection as of 2020 was roughly 50 species and 250 animals, including hippos, Malayan sun bears, orangutans, Bengal tigers, gibbons, flamingos and Taiwan macaques.
