As a taster, my husband and I are doing a cruise from South Island to North Island and will be stopping at Dunedin, Christchurch, Tauranga & Auckland. Being photographers, we are interested in wonderful scenery but will only have a day stop at each of the places. We are looking for suggestions for driving times to interesting and scenic places to visit w/ the ports being our jumping off location. Any suggestions? We'd like to rent a car or small tour. We know there are Lord of the Rings/Narnia locations towards Queenstown. Are they a possibility, logistically speaking?
