I believe Kashin and Burma were still walked around Auckland up until Kashin's passing in 2009.Auckland Zoo walked their elephants through the zoo during visiting hours up until the 2000’s (I recall seeing Kashin and Burma walk through the zoo as a kid; and remember reading how the then 18 year old Ma Schwe tragically dropped dead while being walked around the zoo in 1982).
Going back further and Jamuna and Rajah were walked from the elephant house each afternoon for a swim in the adjacent elephant pool (the plaza separating the two being renamed Jamuna Plaza in her honour).
Burma was walked through the zoo outside of visiting hours up until her export, with the keepers often taking her to bush up the back of the zoo.
I also have memories of the pair being walked around the zoo during visitor hours and I actually have a family photo of the pair being walked up the service path (beside Jamuna plaza) to access the bush behind the zoo.
