Auckland Zoo’s first hippopotamus was a female named Bella. Bella was born 23/02/1921 at Melbourne Zoo to William and Rosamund. Bella arrived at Auckland Zoo 11/12/1923. Bella was joined by a male named Chaka in 1925.
Chaka and Bella produced six offspring together, most of which died in their first week of life. Their last offspring was a male named Dimazulu, who was born in 1937. Chaka died that same year and Dimazulu became the zoo’s new breeding male.
Common Hippopotami Breeding at Auckland Zoo (1929-1937)
I wanted to expand on this information, regarding the offspring born to Auckland Zoo’s original pair of Common hippopotami, Chaka and Bella. They produced six offspring between 1929 and 1937, which was reported by the zoo to be a world record in captive breeding.
This article (13/03/1934) summarises the four births (all males) that had taken place to date and details the export of the two surviving calves to Australian zoos:
Four offspring have been born to the pair of adult hippopotami at the Auckland Zoo, and two have been successfully reared. The first born, in September, 1926, was rolled on by its father and was crushed to death. The second (Pondo), which is shortly to be shipped to Perth, was born in January, 1929. The third, born in November, 1930, was neglected by its mother and died. The fourth (Zulu), now in Adelaide, was born on New Year’s Day, 1932. The breeding of hippopotami in captivity is unusual, and great interest been shown in zoological circles in the success achieved by Auckland in rearing two animals.

From further research, I discovered the fifth calf was born 09/11/1935 and died later that month on 23/11/1935. It’s death was attributed to trauma from adverse weather conditions. The gender of the calf wasn’t known at the time of the birth announcement, but it was stated they hoped the calf was female as the fourth previous births had all been males.
Their sixth calf was a male born 11/02/1937. He was named Dimazulu and replaced his sire, Chaka, as the new breeding bull after Chaka died from swallowing a tennis ball 13/10/1937.
