Figures also showed about 8900 motorists in New Zealand had their exams cut short due to critical errors such as being involved in a collision, driving at excessive speed and ignoring instructions. About 140 were from the Far North.
Mrs Waitohi said working with a qualified driving instructor before a test would help many motorists. The 2011 national pass rate for the previous restricted test was 81 per cent.
NZTA spokesman Andrew Knackstedt said the new test was designed to better prepare novice drivers and the organisation made no apology for that.
"New Zealand has one of the highest rates of teen road deaths in the OECD. We have made it very clear from the beginning that this is a more challenging test and we encourage people to ensure they are adequately prepared before sitting it."
Controversy around the current test flared after an internal NZ Driver Licensing memo was leaked to the media last month saying the pass rate for the new exam should be about 40 per cent. In March - a month after the test was introduced - the pass rate plummeted to 38 per cent.
Mr Knackstedt said there is no quota. "The fact of the matter is that more than 50 per cent of applicants are now passing restricted licence tests.
"People are getting the message that this is a harder test (and) they are putting in more preparation," he said.
