Rewarding good driving through "merit points" has received a thumbs up from motorist groups, although an academic has dismissed the idea.
Merit points could come under scrutiny as part of research commissioned by transport authorities into NZ's demerit system, where drivers rack up points for offences such as speeding and using a cellphone.
Drivers who get 100 points within two years can lose their licence for three months.
The research, which the NZ Transport Agency has put a tender out for, could look at other countries' systems, including those that reward clean driving records. It could also examine the idea of imposing demerits for offending caught by fixed speed cameras.
Mike Noon of the NZ Automobile Association said the AA would support merit points if they worked like an example he recently heard about from a driver in Australia.
