Additionally, 117 warnings were issued for missing P endorsements lastyear but only one was handed out after the law change.
This was a reduction on 2016, when 139 warnings were given out.
Uber did not previously require its drivers to hold a P endorsement, but agreed to change company policy, bringing it into line with the Land Transport Amendment Bill 2017 changes.
The bill was passed in October, after which the number of prohibition notices issued by the NZTA dropped to zero and stayed there.
An Uber spokeswoman said all the company's drivers were now required to have a P endorsement, and the company had obtained the appropriate Small Passenger Service Licence needed to operate a small passenger service.
The endorsement included a police check, evidence drivers were completing log books, complying with work time and had a current warrant of fitness for their vehicle.
"We have been pleased to work with the NZTA on reforms to modernise personalised transport for the benefit of Kiwi consumers and drivers," the spokeswoman said.

'We believe the new framework will benefit both riders and drivers because it makes it faster and more affordable for drivers to get on the road, while prioritising safety."
NZTA spokesman Andrew Knackstedt said "things had moved on considerably" since November 2016, when the Herald first ran a story about Uber flouting the law.
"The NZ Transport Agency is actively working with Uber, as we are with other operators, to ensure that they understand and comply with the new rules for small passenger services, which came into force on October 1."
NZTA was happy with the company's compliance, he said.
