What to do?

Back in Christchurch and said goodbye to my fellow trampers as they head off in their own directions - most back to work, one to continue tramping and another to skydive, canyon, white water raft and all that other fun and adrenalin filled stuff that you can do here in New Zealand. So what shall I do and where shall I head? I am now in 'free' mode and from this point on I have nothing booked or planned other than my flights to different countries, though I always have a few thoughts knocking around in my head - usually too many thoughts but I am getting better at that! As I am well into my NZ budget I need to consider costs as well as what and where I want to go. After a day trolling the internet and visitng the Christchurch tourist information I opt for car hire, a map, a tent and a picnic cool bag. The cheapest camper van I could find was $102 per day whereas the cheapest car was $30 so considering I would still need to pay for fuel and campsites on both I opted for the car. Having been in NZ for a little while now I also decided the car gave me a little more freedom as I could choose between camping and staying in Backpacker hostels (dorm ~ $25) - both of which are usually fully equiped with big kitchens and cooking equipment, and if I needed a little extra luxury I could book into a motel for a night. The Backpackers are also a little more sociable than being in a campervan as there are usually people milling around and willing to talk about their adventures. The destination would be the north of the south island, east and west, but no real plan - and I am off again!
