This was a bit pricey, but looking back after the trip, and my entire family thought this was the best thing we did. Better then skydiving, bungy jumping, luge, ziplining, and black water rafting.
We started out on a boat ride to see some of the native sea birds and seals, that was interesting but not really a bonus for us. Then we walked quietly through the woods, and tried to find the wild kiwi's. We had no luck and finally reached the beach. You could tell our tour guides were worried, because they want to let you experience the kiwi in the wild. After much time on the beach, we started back, still without seeing a kiwi. Although a highlight of the evening was watching one of the guides get chased by the seal. She did a great job putting herself in between the group and a really pissed off seal, that was amazingly fast. There are many ways to handle a wild animal encounter, and she used what she was trained to do. I might have done things a bit different, but we were safe and got to place some bets between us. On the way back they had both guides and a third guide looking. They finally tracked one, and it took another hour to finally see the kiwi for a brief 10 seconds. I don't care who you are watching the kiwi for even 10 seconds was so awesome. This from a family that has been around the world and on multiple safari's in africa. This still was super cool.
We would do this again in a heartbeat, and would recommend you going as well. The guides worked super hard, and you have to understand that some nights you may not see a kiwi. If the company offered a 50% rebate if no kiwi was spotted, then this would be the ultimate destination. However, going back to the boat without seeing one was going to be tough, although we enjoyed the actually hiking trek. We were saved by the last second kiwi encounter.
