I visited Auckland Zoo on 30 December 2012, here are some of my observations.
-There is a new map (still free) which is good. One thing it cleverly does, is to colour each animal's exhibit according to continent of origin (NZ, Australia, Asia, Africa), although the exhibits in the Tropics area haven't been coloured for some reason.
-Upon entering the zoo, you are now encouraged (strongly) to be photographed, which makes one feel a little like a common SeaLife visitor.
-The new Porcupine exhibit is really quite good, the animals weren't visible on arrival when the zoo opened, but when I re-entered the house at 12.30 they were active and ambling around. They are so big! Extensive and excellent signage.
-The old native bird aviaries now holding the Australian parrots and bats are nothing stunning, I don't really undertand the point of moving them (except the bats). The cockatoos definitely have less room. New signs here too.
-There has been a baby Red Panda born to Bo.
-The main otter enclosure was empty, with all signage removed. One otter is now displayed in the old porcupine enclosure (

-Te Wao Nui was pretty much the same, still no Archey's Frog, although interesstingly the old frog house is having some extensive work done. Not clear what this will become. Stick Insects and NZ Praying Mantis have moved into The Night, but still couldn't see the lone Short-tailed Bat. Sea Lions and Fur Seals very active (

-The walkthrough lorikeet aviary was closed, with no birds visible. Some of these (Mallee Ringneck, King Parrot) have moved to the old native bird aviaries, while others (Rainbow Lorikeet, Crested Pigeon, Masked Lapwing) have moved into the old Black Cockatoo aviary.
-The Kookaburra and Monal are no longer on display, nor listed on the census.
-Bolivian Blue-legged and Andean Stripe-knee Tarantulas are on display in the old giraffe house, no Mexican Red-knees.
-The Flight Aviary is looking bare and poor, only the Blue and Gold Macaws, and a pair of Eclectus Parrots are displayed here. The Scarlet Macaw cross is gone.
-The Flamingoes have built nests, and were hanging around these, some sitting on eggs. I don't know if these are real eggs or not, hope they are (

Overall, the zoo was looking great, the only disappointment being the cull of interesting species (especially birds) and the confusing relocation of Australian birds without apparent reason.
I have photos of almost every exhibit, so if you want to see something let me know.
