Two flamingo chicks hatched at Auckland Zoo on December 27 and January 8.
They are the first to have been bred in Australasia and the only chicks known to have been bred from a completely hand-reared flock.
The sex of the new arrivals is not yet known.
They are yet to grow the pink feathers the birds are famed for.
Auckland Zoo's flock of 16 flamingos was hand-raised at England's Wildfowl and Wetlands Trust before arriving in New Zealand in 2001.
It is New Zealand's only flock.
Having no contact with adult flamingos mean the birds learnt their survival skills from humans.
These chicks will also be hand-raised.
The zoo's Pridelands team leader Nat Sullivan has been monitoring the chicks' progress since incubation.
"They're doing really well communicating with each other which may be why the second chick is making even faster progress than the first," she says.
