This is a very different type of tourist experience. Leaving by boat at 9pm we were lucky enough to see seals and penguins along the way. Then a two hour tramp around in the bush with two excellent guides, Erin and Robyn, and we saw two kiwis going about their nightly business very close up. Arrived back at our accommodation about 1.30am exhausted but very happy. Highly recommended but you need to be reasonably fit and mobile. Not kid friendly.
