In New Zealand we drive on the left hand side of the road - the opposite to Europe, USA, Canada etc. If you have not driven on the left hand side before there are a variety of helpful videos to prepare you and your consultant can advise. The best advice though is to take it easy at first and have your passenger as a co-driver to remind and help you become accustomed to driving this way.
Or get in touch with the team if you have a specific question.
