Getting your licence in New Zealand is a three-step process.
You must get your learner licence before turning a wheel on the road, and the minimum age is 16.
You must be 16 and a half (or more) and have held your learner licence for at least six months you can take a practical test.
Again, you can choose a practical test or a CBTA route for obtaining your full licence.
If you choose the practical test you need to be at least 18 and have held your restricted licence for 18 months or more before you can apply for your full licence, then take the test.
Taking training before your CBTA assessment will give you feedback on your riding and make you more confident on the day. A Ride Forever course is ideal and your trainer is almost certain to be a CBTA assessor.
