"The ultimate aim is to have less tragedies on our roads," Rotorua District Council road safety co-ordinator Jodie Lawson said.
"I guess if it's harder it's making sure that those getting on to the roads are better for it."
Figures also showed about 8900 motorists in New Zealand had their exams cut short because of critical errors, such as being involved in a collision, driving at excessive speed and ignoring instructions.
About 200 people were from the Rotorua district.
Ms Lawson said people had to put more practice in if they wanted to succeed under the new test.
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."
But Mr Knackstedt said the pass rate was expected to climb gradually as people recognised the need to put in more preparation and latest figures suggested that was happening. The pass rate has risen from 38 per cent in March to 52 per cent last month.
Controversy around the current test flared after an internal NZ Driver Licensing memo was leaked to the media last month.
Written by national operations manager Gerard Clark, the memo said the pass rate for the current 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 denied the existence of set rates. "There is no target for pass or fail rates and there is no quota. There is however, an expectation that the test will be applied with a degree of consistency around the country.
"The fact of the matter is that more than 50 per cent of applicants are now passing restricted licence tests," he said.
"People are getting the message that this is a harder test [and] they are putting in more preparation."
