My partner and I are driving from Christchurch to Auckland starting Feb 24 afternoon Christchurch airport, finishing Feb 26 Auckland airport. It's a big self-contained RV. Will stay 2 nights at free campsites. Can take up to 4 more people for any section of the trip (chip in for fuel). Plenty of space for luggage. Taking the morning ferry Feb 25.
