I spent a month in New Zealand in January / February and I agree with the above. The South Island is definitely more scenic. My (rough) itinerary was:
- Fly into Christchurch (not much there - so don't feel like you need to spend long there!)
- Hamner Springs for the hot pools,
- Hamner to Kaikoura for Whale Watching
- Back to Christchurch to meet with family
- Scenic drive to Akaroa for Dolphin Swim
- Head west to Franz Joseph driving through the Southern Alps. The drive through the mountains was stunning! We did a few short walks to break up the journey.
- Franz Joseph we did a 1/2 day glacier hike and helicopter ride (I'd highly recommend the helicopter!)
- From Franz Joseph we head west to the coast and then south down the coast to the Mount Aspiring National Park. Mt Aspiring National Park was STUNNING. There are litterally so many photo oppertunities with 2m from the road.
- We then headed to the lake district and stayed in Wanaka and Queenstown, both of which have some amazing walk and photography locations.
- From Queenstown we went to Te Anau and did a boat trip to Doubtfull Sound, and we did the drive to Milford Sound. Both the Sound's are stunning and I can recommend doing either, but don't feel like you need to see both. Milford Soun is more touristy, but the drive there is out of this world!
- We then head back to Queenstown for a few more day and then on to Lake Tekapo to do a star gazing tour.
Here is a link to some of the photos I took, I only had the DSLR for a couple of months. But you get an idea of the locations I visited.

For budget car rental look at Rent-a-dent. They provide budget cars and were a 1/3 of the price of Europcar etc.
