Lake Tekapo is another one of those and has some nice small lodges and camping grounds nearby as well as an observatory of the souterhn sky. Unfortunately there's a lot of cloud cover, so even though the area doesn't allow light pollution, clouds plus a full moon prohibited a good viewing experience. The night was also somewhat interrupted by an earthquake even though I felt very little of it and only heard about all the damage it did near Kaikoura on the news the next morning.
