What a great place in the city to view so many of New Zealands native creatures!
Parking can be a challenge as it is a very popular attraction and even with their overflow car parks they can become full, with the constant flow of people you're not likely to be waiting too long for a spot though.
From the introduced section with the deer you can hand-feed to the farmyard section full of all kinds of farm animals to get up close and personal with you'll be spoilt for choice when it comes to choosing your favourite animal.
The unique New Zealand birdlife plays a key part in the walk through the reserve with the Kea enclosure letting you get up close and personal with the cheeky alpine parrots and the feeding times of various animals through the park let you see how well looked after and cared for these animals are.
The Kiwi exhibit is of course under dark lights and you definitely need to take care when walking around the area. You're pretty likely to hear the Kiwi before you see them so keep your ears open and let your eyes adjust to the darkness.
The Eels right at the start of the reserve are a great entry point, I'd say a solid 3/4 hours can be spent here enjoying the wildlife and it's a great introduction to any tourists who aren't aware of the variety that New Zealand has to offer. Pretty reasonably priced for the amount of time you can spend here and unique animals visible and the year long pass is a great option for locals.
Cafe/Restaurant available near the entrance however we didn't venture in and the gift shop is full of wildlife themed gifts and presents!
