Hamilton Zoo has launched a public naming competition for its two sumatran tiger cubs.
The cubs, a male and female, were born to mother Sali in November last year.
They're part of a global breeding programme for a species identified as critically endangered, and are the progeny of 11-year-old Oz (who came to the zoo from Auckland Zoo last year specifically to breed) and 7-year-old mother Sali.
Samantha Kudeweh, Hamilton Zoo curator, said the time has come for the furry cuties to be given names.
"These little cats are very precious and very loveable, and we've been referring to them by the nicknames 'Roly' and 'Smudge'. They've really thrilled our visitors - and now we want people to have a sense of connection toward them."
