Jack's place was terrific, and he is an incredibly nice person himself! The apartment is extremely clean and very well maintained. It is close to many attractions in Central Auckland, and is a short walk to the ferry. The apartment complex is also very safe -- requires key fob to enter building and also individual doors in the apartment all lock. The room also came with a converter from US outlet to NZ outlet if you need it. I definitely recommend staying here to anyone and my friends who may visit.
He also speaks Chinese fluently (in addition to perfect English), so it was nice for my mother to be able to chat with him.
