Yesterday, after extra feeding and antibiotics, the chick was ''perky, chirpy and hungry'' and its weight had bounced back, she said.
It was removed from intensive care and placed back in a foster nest, where it would continue to receive antibiotics, she said.
But, all going well, the chick would be returned to its parents' nest tomorrow, she said.
News of the chick's arrival on Saturday was met with excitement after its predecessor, Moana, shot to internet stardom last year.
Moana was the first chick to feature on Doc's Royal cam, and coverage of her progress attracted more than 600,000 views until she fledged, and flew away, last September.
Updates on the new chick's progress also attracted online messages of support from around New Zealand and as far away as Australia, the United States and England yesterday.
