You can rent cars, mini vans or 4WD vehicles at the main towns in Otago – Queenstown, Alexandra and Dunedin. Some accommodation hosts will also rent you a vehicle so that you can explore their neighbourhood.
Having your own 'wheels' gives you more freedom to explore Central Otago. Those who like doing their own 4WD adventures have plenty of country out there to explore.
Some rental companies have restrictions on driving on gravel roads (this is more likely to result in accidents) so check your agreement for insurance purposes.
