"They have now opened their eyes and are moving about in the nest box a little more, and will sometimes 'huff' at us," she said.
"Their weights have shot up to 403 grams and 423 grams respectively - above average, so we know they're getting plenty to eat, but they still have more growing to do," Ms Booth said.
Like their older brother Pabu - born just over a year ago - the twins will eventually relocate to a zoo in Australia to contribute to the international breeding programme, she said.
While visitors to Auckland Zoo are able to see the twins' brother and their parents, the new additions to the family are not expected to venture out of their nest box until sometime in March, when they will be at least 12-weeks-old.
The sex of the cubs will also be confirmed that month, at their first vet check.
