After some great advice on here I have put together this itinerary for our campervan self drive around the island. We are flying in from Sydney at midnight and collecting our van the following morning. If you know of anywhere to visit that we dont have in (particularly on the drive days it would be super!)
Day 1: Collect camper in Christchurch

Day 3: Mt Cook-Queenstown pm explore
Day 4: Dart River Jet Boat and Funyaks experience
Day 5: Milford Sound Nature Cruise (coach-cruise-fly)
Day 6: Hot air balloon (weather permitting) Drive on to Lake Wanaka (possible skydive)
Day 7: Drive Haast Pass to Franz Josef
Day 8: Franz Josel heli hike pm drive to Punakaiki
Day 9: Explore Punakaiki in the am. Drive pm to Motueka
Day 10: Abel Tasman: Tonga Island seals kayak/walk/cruise
Day 11: We want to do a good wine tour here in the Nelson/Marlborough area!! Recommendations needed please!
Day 12: Drive to Kaikoura
Day 13: Dolphin watching tour (very early am) Maori Tour perhaps in pm

Its pretty hectic but I think it's achievable! Let me know if we need to tweak!
