Learner licence theory test

The learner licence theory test is a computer-based, 35-question, multi-choice test that assesses your knowledge of road rules and safe driving practices. You will need to get at least 32 questions right to pass.

Everything you need to pass the test is in The official New Zealand road code. You can buy the road code at most bookstores and driver licensing agents, or it’s available online.

Once you have passed your theory test, the agent will give you a temporary learner licence so you can start practising your driving. Your photo driver licence will be posted to you.
